2)Of these races, which traits make someone a part of such race? In otherwords, which traits make you black, etc.

 

[with.buddha]

6.2 billion races - nearly all are different from each other.

all of the races tend to have similar traits based on common ancestors, the further you go back the more common traits between all 6.2 billion races.

[Another God]

Thanks to technology, leading to rapid transport means, all previously segregated potential sub-species of the Human race have been allowed to interbreed, ending the progression down that path.

How many races? Well, 1 really, because there wasn't enough time for the isolation to kick in...

 

[russ_watters]

But to answer the question, races are defined strictly by skin color or ethnicity. Thats not a scientific definition though.

There are a few other traits that go along with race, such as the extra flap of skin on asian eyelids, but these differences are extremely minor. There aren't any important traits that are different between the races.

Some people have tried to prove differences in the races for the purpose of justifying their racism ("The Bell Curve"). Such attempts have had no scientific validity.

A. I do not think there is a biological concept of race. Rather, biology recognises that populations vary intraspecifically, and some of this can be related to the geographic location they came from. There is no dividing line between races. Rather, the concept of race is generally a political or religion issue. And this is dependent on government.

B: There are no, to my knowledge at least, internationally recognised listing of races. So, there is no set number. The definitions of these also vary.

race

Hi GlamGein:
If you would like more on this subject, an obviously controversial one, check out the following:
http://isteve.com lots of stuff there, also plenty of links, and his definition of a race.
also this one http://www.racearchives.com/archived/

If you are of a mind that race is merely a social construct, with no underlying genetic basis, I would recommend that you not check out these links.

 

[GlamGein]

I want to thank you for answering my questions in a sincere manner.
But I posted this in order for us to all think about the question, because someone posted a question about race and intelligence/superiority, and many posted as to saying that they believed there was a correllation between race and intelligence. Any reputable biologist will tell you that race is merely a social construct. There is no biological basis for race.
And thanks for adding those links, they proved useful in my research.

 

[FZ+]

amos behavin: why would I not check out these links? We don't all want to self delude...

But I point out the key here is "biodiversity". There are differences within species. But to imply a clearly defined line of race - ie. this person is one, this another is a naive and unscientific manner. Clustering does exist in some rather arbitary attributes by fortunes of history mostly, but there is no dividing line scientifically speaking.

race

Hi FZ+:
Thank you for the well thought out response. I agree with you that not all individuals can be, by any set of criteria, assigned to one race or the other. but I disagree that that problem means that races do not exist. If one considers Biological species, using Mayr's Biological Species Concept, or the Morphological Species Concept, both widely used by Biologists, one also finds that clear lines of distinction are not present between species. But, species do exist.
And consider the Ecologist recognizing that a forest is covering one geographical area, and a grassland is on an adjacent tract of land. Generally there is an area between the two where one cannot logically draw a line of clear demarcation between the two. Yet, a forest and a grassland are clearly different. To borrow an example from Steve Sailer, mountains and plains are distinct, different geological features, also with no clear cut line of demarcation between.
This is an obviously emotionally charged issue for a lot of folks. I don't want to touch on this so called superior/inferior business. My comment about "don't check it out etc." was clearly, I can see, not intended for you.
As you surely know, a scientist must consider all evidence, and approach a problem with as much objectivity as humanly possible. One cannot ignore particular bits of evidence because one does not like the effect that said bits of evidence will have on the conclusions.
A previous message here is from a person who claims that he/she was conducting research on this topic. For those readers who are presently students intending to pursue a career in science, that was an example for you of how NOT to conduct research. Consider all of the available evidence. Test your hypotheses fairly and objectively.
I have been reading for some time articles in which the authors state, as one poster here did, that race is purely a social construct. I see such a great deal of irony in that the Medical community increasingly is recognizing that the race of the patient often dictates what treatment should be administered to effectively treat the malady.
Again, thank you for the response.
Amos

 

[GlamGein]

Amos:
I have some issues with what you posted.
First, you said that despite the biological species concept, et. al, showing no clear demarcation between species, there ARE species. How do you figure? Where is the evidence?
Second, you mentioned something to the effect that scientists are treating race related diseases. Well, are these diseases based on GENES or ENVIRONMENT? Often people of certain races belong to distinct social classes, which is a determinant in infectious disease due to sanitation, access to medicine, nutrition, etc.
Why is it such a bad thing to believe that there is no biological race? I have faced a lot of resistance to this FACT.

 

[amos behavin]

Hi Glamgein:
A quick example that Biological species do exist, especially if one invokes Mayr's definition (being able to interbreed, they are the same species). A mouse and an elephant cannot cross and produce fertile offspring I'm sure you will agree.
The medical community is treating various disorders with treatments tailored to a person's race in some cases. Perhaps spend a little time looking at the articles on the second website I listed in my response to your post. There is one recent article there about the differential effectiveness of a particular AIDS vaccine. It's a little late for me here tonight, but I'll find you some more tomorrow if you don't encounter some yourself in the meantime. Maybe you can try a Google search.
As far as it being "bad" to recognize that there are or are not races, you're putting a value judgement where none need exist. One could easily ask, I suppose, "Why is it bad to recognize the existence of races?" Science, when dealing with a topic such as this that can be determined to some extent with some objectivity, should avoid these types of value judgements in my opinion.
Stepping out of the Biological realm for a moment, and looking at this issue judgementally, I think that the research that shows that there are differences in the effects of medicines, vaccines, treatments, etc. for people of different races, is valuable. I believe that it would indeed be bad if this research was ignored or suppressed because it recognized that people can be classified as to race. People dying because of someone's insistence that race doesn't exist would be considered bad by any right thinking person, don't you agree?

 

[GlamGein]

Amos,
I would love some more articles that shed light on your point of view.
I understand the concept of species, and the biological species concept. I believe that there is a human species, but I do NOT believe there are human sub-species, as proponents of biological race would claim.
As per medical advances for races, which advances are these? Are they genetically based? What makes a black person more susceptible to certain diseases or whatnot, than a white person? Is it race? Or is it socio-economic factors?

[amos behavin]

Hi Glamgein: To see some articles about this, go to the "Human Races, Archives, Evolution" website previously cited. Find, on the left, a column headed "Debates". Click on "Full Listing". You will find about 7-8 articles just right there. Also, check out the archives on the other site. Steve Sailer also has a category, on the top of his page, called "Race". If you click there you should also find some articles. Also, a Google search, using "'race and medicine" treatments"' will produce some articles. You are correct that the environment in which a person has developed and now lives is important. But, if you will look at some of this research, you will see that those studying this are well aware of that. You should also find, allowing for environmental conditions, that the research is indeed finding that there are important genetic differences that correlate strongly with race. Now, I say this with no malice whatsoever, but I am surprised that you had not ever encountered any of this information if you were indeed conducting research on the Biological aspects of race.
You stated earlier that "any reputable biologist will tell you that race is merely a social construct". Anyone reading this who takes a little time to do some reading on this topic will see that your statement is clearly inaccurate.
Also, stating that something is "FACT" using capitol letters does not add any weight to your argument. Please provide some support for why it is "FACT".
Thank you,

Actually there are two separate reasons: One is heredetary (things like sickle cell and heart disease). The other is exposure. The flu killed millions of indians not because they had a genetic predisposition to it, but simply because they had never been exposed to it before.

 

[amos behavin]

Hi Russ:
I don't think that you are looking at that correctly. But, then again perhaps I'm not understanding what you are trying to say. The Indians (I assume you are referring to Amerindians) suffered such high mortality rates from the flu, and other infectious diseases, because there was less resistance for genetic reasons. The Europeans had been subjected for generations to selection forces that eliminated most of those who had no resistance, because of the presence or lack of particular alleles that conferred resistance. Severe outbreaks of a disease like the flu would cause the formation of a genetic bottlenecks with each occurrence.
I think maybe where you are coming from is this: During the first epidemic of something like the flu, virtually all members were infected with the virus. The survivors, mostly those who possessed in their genomes some alleles that conferred some degree of resistance to the effects of the virus, would not be nearly as severely affected by a return of the same strain of the virus at a later date. This is due to the secondary immune response. So, you are correct that one would expect that a lower percentage overall would be affected the second time around. But, the children born after the first outbreak, at least the ones who did not have some genetic based resistance, would be affected more or less at the same frequency as before.
This example you propose is Darwin's natural selection model clearly illustrated in my opinion. Here is how it appears to have played out in your example. The first outbreak of the disease eliminates most of those in the population who have no genetic based resistance. The survivors pass on to their children their alleles for resistance. Thus, the frequencies of these adaptive alleles increase. With each introduction of the virus into the population, those members who possesses in their genomes these adaptive alleles survive in higher percentages, and those that lack those alleles die, reducing the frequencies of the non-adaptive alleles. With each disease event, fewer members of the population die because more members possesses in their gemomes the alleles for resistance.
The flu, measles, and some other diseases presently have a much less severe impact on these populations today. That is because the living members of these populations are the descendants of those who survived; they possesses the adaptive alleles for resistance. I suppose, although I certainly don't know for sure, that these adaptive alleles may be approaching fixation in these populations.
I appreciate any feedback. Thanks Russ.

Is that really what happened? Thats not the way I understood it. I certainly could be wrong.

Genetics aside though, resistance to disease does depend a lot on whether or not you (or your group) have been exposed to it before. Thats what an immunization does - it gives artifical exposure to create a resistance. That works for individuals and for groups.

 

[GlamGein]

Amos:
The reason I posted on this forum was to get away from "academic" studies, which, as we all know, can be highly biased and innacurate. As for my statement that biological race is invalid, it is, indeed, a FACT, in capitals. The area that lacks scientific "weight" is your argument FOR biological race. Name one characteristic, allele, whatever that says that one person is of a certain race. Its impossible. Dark skin doesn't make you black. Sickle-cell trait doesn't make you black. I said that any reputable scientist will tell you the same thing, the key word being reputable.
If you believe in definitive race, please describe definitive racial alleles and traits. I am merely trying to understand how you came to your point of view.
As I have stated before, of all human variation, 85% of it can be found WITHIN populations. Race is based on the few characteristics we can see and account for, which should not be weighed heavier than the other variation that is less obvious.
For example, it was found that indonesian pygmies were more closely related to the indiginous (stereotypical) indonesian population, than they were to african pygmies, despite the fact that the layperson would have put them in the category of pygmy. What race are they?

 

[GlamGein]

Russ

Let me clear up the "Amerindian dillema".
The indiginous people of North America sufferred from pandemic smallpox, and other infectious diseases, that some scientists believe wiped out 90-95% of the indiginous population. While I don't believe the numbers are that high, but it was enough to irreparablly damage many cultures. It was smallpox that was most deadly. They died for both genetic AND simply because they hadn't the chance to build up a resistance to the disease.
An interesting aspect about genetic resistance to smallpox has to do with the ABO blood group. WELL, type O provides some resistance to the smallpox disease. I don't believe it is a coincidence that over 85% of modern Native Americans have type O blood.

 

[amos behavin]

Hi Glamgein:
The part about the Indians dying because of genetic reasons and because they had not had a chance to build up resistance is exactly right. That is to what I was referring when I mentioned that the survivors of an exposure would rely on the secondary immune response, the build up of memory B lymphocytes etc. So, I really don't think there is any disagreement between us on that matter.
As far as the other issue, I have only seen one reason that you have given thus far that race is a meaningless concept in Biology. That is that somebody might claim that one race is "superior". I think that you and I are probably basically in agreement that the terms "superior" and "inferior" could not really be logically applied to races.
Please do this. I will be away from a computer the next few days for the most part. If you have the opportunity, please read at least the following articles:
"The Straw Man Of Race" by Jon Entine
"Seven Dumb Ideas About Race" by Steve Sailer
Perhaps next week, you and I, and anybody else who cares to, can discuss these articles. Pick out particular passages and tell us why the author is mistaken, and then provide some support for your argument.
Also, as far as reputable and not reputable Biologists, please if you can, list some of these not reputable Biologists for me and the readers to look at.
Back to the part where you select specific loci and ask if the particular alleles at those loci confirm a person's race. Do a little homework on haplogroups, groups of genes rather than individual loci, that seem to be very good indicators of these categories we call "race". Perhaps then you can comment on the accuracy of forensic pathologists who can determine race by various quick methods, so that they are able to do so with remarkable accuracy based on a small sample of blood or semen or tissue, even looking at the gross anatomy of a skeleton.. Try going to Google and searching for "haplogroups, race". You will find plenty to look at.
Have a nice weekend,
Amos

Hi Russ: The resistance that comes from a previous exposure is the secondary immune response, the buildup in a persons's lymph tissue of memory cells for that specific antigen. Maybe I misunderstood you, because I detected some sort of Lamarckian inheritance that your message seemed to imply. Glamgein's response about the smallpox seems to indicate to me that she is also invoking some kind of Lamarckian inheritance of acquired characteristics. The immunity built up in a person due to proliferation of memory cells is not, to my knowledge, passed on to the offspring. Therefore a second exposure of a population to the same strain of pathogen should result in the previously exposed individuals suffering little ill effects. But, new members of the population, those born after the first exposure, would not have any built-in immunity as a result of their parents having been exposed. The only resistance they would have would be if they received alleles from their parents that conferred immunity. These alleles in the parents would not have been altered by the parents exposure to the antigen. If I misunderstood you I apologize.

I frankly don't know some of the terms you are throwing around there, but when I said it is possible to inherit a non-genetic immunity, I was talking about a baby sharing its mother's blood and drinking her milk.

Russ, this not inheritance. The baby does not share its mother blood, and the milk provides antibody that protect the guts and the baby acquires an immunity. What amos is talking about is a natural immunity such as the number of immunity type cell and how sensitive they are. People with a balance number of immunity type cell and with a balance sensitvity have an advantage vs. people with fewer or too many immunity type cell and hypo/hypersensivity. People with fewer immunity type cell and hyposensivity tend to be sick more often and longer. People with too many immunity type cell and hypersensivity tend to have allergies.

 

[FZ+]

Hmm... doesn't antibodies get into baby's bloodstream through through the placenta? That is sort of sharing of blood, and accounts for many inherited immunities.

As to allergy, there is some evidence of that being based on early exposure to bacteria from the environment.

Sharing component of the blood is not sharing blood to me. To share blood you would have to share the whole think. When you take about inherited immunity it is a the genetic level and its less secific. The antibodies that are share help to protect the baby because it does not produce antibodies yet. The antibodies share by the mother with her son will be lose sooner or later. Therefore the baby acquires an immunity and it also activates part of its memory cells. If it is was inherited the baby would not lose it.

The research your are taliking about explain that oversanitation created an aseptical environment and does not immologically challenge the infant. Therefore the infant becomes hypersensitive to any antigen. Bacteria and parasite in the environment immologically challenge the infant and the person reaches a balance sensivity.

What I was talking about is taht some people have higher cell count do to genetic and it has been links toa specific of white blood cell call the basophiles, and to a specific type of antibodies called IgE.
The environment could also play a role in the regulation of basophile and IgE. Therefore some allergies are link to the environment as an infant and other are links to our genetics.

 

[FZ+]

Back to the topic itself, I still say this ties in more with the fact of genetic variation among the human species, rather than the unscientific and undefinable notion of race. (Amos: Unlike race, species does have the advantage of a biological differentiation - no-interspecific mating) The reason you have x immunity is not because you are black or whatever, but because you have the x gene. It may be that x genes occur more frequently in black people, but it is not a genuine link. In an analogy, more rich people die of lung cancer. Car owners generally are more affluent than non-car owners. So, does owning a car cause you to have lung cancer? No, there is a statistical correlation, but the act of having a car has nothing to do with lung cancer. Hence race is useful for some generalised statistics, but is not reliable enough to base actions around. Not least in this new interconnected society.

 

[GlamGein]

FZ+
I think you hit the nail on the head! Thanks for articulating what I did not.

 

[amos behavin]

Hi FZ+:
I agree with Iansmith. There are immunoglobulins that pass through the placenta to the child, but these do not confer any long-term immunity to the child. Let's look at a common disease that affects most people when they are young. If a ten-year old girl contracts measles, a clone of lymphocytes will, in addition to producing antibodies for that specific measles antigen, also form memory cells that will provide for an amplified immune reponse should she ever be exposed to that measles antigen at some point in the future. But, if she has a child, that child at age ten will not have any better resistance to measles than if the mother had never been exposed.

As for the recognition of races being unscientific, please provide some support for that statement. The recognition of ecological races and ecotypes is all over the Biological literature. Check out all the the research done by Clausen, Keck, and Heisey beginning back in the 1940's. Then please consider the ecology and genetics and taxonomic journals that are full of articles in which researchers recognize races within species of birds, reptiles, amphibians, fish , mammals, angiosperms, ferns, Protists, Fungi etc. Please look over some of the methodologies that these researchers have used. Then, please explain why those methods, which virtually all Biologists seem to have no problem with when applied to all of these other organisms, are suddenly "unscientific" when applied to Homo sapiens.

Agreed. We were starting to argue over minutia (sp?) but that got us back to the point.

As for the recognition of races being unscientific, please provide some support for that statement.

Its easy when you talk about something like black vs. white. But what about English vs. German vs. Danish? In the US we lump together all whites under "caucasian." Serb vs. Croat? Korean vs. Japanese? Jewish (race, religion, ethnicity?)? These divisions are based largely on non-biological differences such as religion or geography. It could be called ethnicity, but its treated the same as race. The racial lines in humans are far more blurred than they are naturally occurring in the animal kingdom.

 

[damgo]

There's a fair bit of work on this related to language affinity and also ancient history. You can find a good tree here:
http://www.unc.edu/courses/soci011/hs5/hs5010.jpg

Like russ noted, this differences aren't what you might think they'd be based on the usual cultural/geographical notions. For example, European caucasians are virtually genetically identical to Middle-Easterners, and related rather closely to Indians; while there is a huge genetic split between north-eastern Asian populations (Japanese/Korean/Tibetan) and south-eastern ones (Chinese/Thai/Malaysian).

Hi Damgo

Great links. Nicholas Wade is a fine writer on human genetics.
And, this guy Sykes is a real character. I've read some about him before. He's apparently a tireless researcher, but he don't mind making a buck, too.
This is a field of study that really seems to be taking off. This is a way to piece together a lot of history that up until now there wasn't much of a way to do so.
Stuff like this: How many gene pools have contributed to the present gene pool of a place like , say, Germany? Or maybe Turkey.
Turkey contained at one time within it's boundaries a Hittite empire. I believe back about the time of the Patriarch Abraham. The people who wrote the Gilgamesh epic I believe preceded the Hittites. And there were undoubtedly other peoples there before that, maybe some of those early cultures (Bell Beaker etc.) that were in Europe way back. Then there were the Greeks and the Persians for a long time moving back and forth. And also Medes, Assyrians, Parthians, Kurds, Armenians and lots of others. About 300 BC a bunch of Celts showed up and became the Galatians. And still others: Romans and Scythians and Goths and Phrygians and Cappodocians, and Pontians, and Lycians, and Jews ( the Apostle Paul was from Cilicia I think, in southeast Turkey). Later on, the Arabs, then Turks, and Mongols, and European Crusaders. One wonders whether genes from the Vandals might be in there also. A Byzantine Emperor, in the sixth century I think, got fed up with them and went to North Africa and sold the women and children into slavery. I read that he split up the men into small groups and mixed them into military units, most of which were in Turkey and Greece. Can anybody add anymore? Again, thanks for the links.

[selfAdjoint]

Back to the topic again. Is race real?

If race is a social construct then so is species. Several posters on this thread have set forth the criterion "If they can interbreed, then they are in the same species". But it's not so simple. Consider North American canids (dogs, wolves. coyotes, etc.). There is a small but definite gene flow among all of them. There is no guarantee that some wolf doesn't have one or more poodle alleles in its genome and vice versa. One species, the Red Wolf, seems to be nothing but a grey wolf-coyote cross, but some zoologists refuse to admit this.

Or what about the cases, described in biology textbooks, where a number of populations are strung out in a long pattern (in one striking case, it's birds strung around the arctic circle). Each population interbreeds with its neighbors, and looks like them too. But if you take populations far apart in the string they don't look alike and if brought together they won't interbreed. Is there one species or many? If many, then how many? Where do you split up the populations?

So "species" is just a tradition from prescientific times (Linnaeus - 18th century), not a well defined scientific category. Maybe we should just confine ourselves to talking about stable populations, and leave the generic words for the ignorant.

And talking about stable populations, the intermarriage rate of Blacks and Whites has been stable for decades, about one half of one percent of all marriages in the two populations. That's a small enough gene flow that some zoologists would say "species".

 

[amos behavin]

Yes, but

There is considerable gene flow between populations of different species, either through direct interbreeding or introgression. You cite some excellent examples for why it is often very difficult to draw a line of demarcation between species. Nature has a way of resisting human efforts at pigeonholing. But, I still maintain that species do exist. I cite my previous example, one that I first heard when it was uttered by a professor in a graduate ecology class, in response to this same problem; A mouse cannot cross with an elephant. So, I propose that species do exist, it's just awfully confounding sometimes when one tries to recognize the boundaries between them. Thanks for the excellent contribution.

[The_oMeGa]

I know this is an old subject now, but i don't think there is a term "race" in biology. Race in the common trane of thinking is a group of Genetic traits in the biological world. If races intertwine, (or mating of 2 different races) then the genetic pool is mixed, forming its own unique race.

 

[amos behavin]

hi The_oMega

I typed in on Google "race biology" and got 480,000 hits. Not all were race in this context, but most that I perused were.
Here is an interesting article on this controversial topic:

[GlamGein]

amos:
I appreciate the links. This last one didn't convince me of anything, though. Again, its just "I think one way" vs "I think the other way", which is the main reason that biological race is an argument in the first place. Some people just can't accept facts.

Hi Glamgein:
I think you are being a little hard on yourself. You did finally accept that species do exist, didn't you? So, I think you are making a little progress.

[Another God]

Species exist..races exist... meh, whatever. UNder the evolution paradigm, if you are to be true to reality, then you have to accept that Species is an artificially placed line, just as races are on humans.

If you look at Nature in its full 4 dimensional splendour, then you will see that we are all one organism. How can u divide it up, and claim to be objectively correct in your divisions?

 

[amos behavin]

All one organism? Please explain. It seems that your premise is that no distinctions can be made between one type of organism and another. So, if one is walking in the woods, encountering a mouse and encountering a grizzly bear should elicit the same response?
No lines can be drawn, so the whole exercise of assigning categories is futile. You do that all the time (in the real world). According to your logic, one should not distinguish between red and blue because there is a color called purple. There then is no distinction between the ocean and dry land, because there is no clear line of demarcation on the beach. If you actually, really, truly believed what you wrote, it is, in my opinion, a miracle that you are still alive. You should have walked into the ocean (or what others recognize as the ocean) or stepped in front of a speeding car (there is no "fast" or "slow" because speed varies continuously). But, what the hell, if the grizzly bear eats you that's no problem because you and it are the same organism.

 

[Monique]

Well, I wouldn't say one organism, but AG refers to that we are all made up of the same four letter code ACGT. All genetic diversity is based on the sequence of only those four letters. If you look at a mycoplasm or an elephant, both have the same foundation.

 

[amos behavin]

Same DNA components, yes

Hi Monique: Perhaps that is what he meant. But, please consider this definition of an organism:
"A living entity that has (or can develop) the ability to act or function independently."

I propose that being made of the same kinds of molecules doesn't mean that two entities are the same organism. Two dogs are two different organisms out in the real, tangible world. Likewise two, say, loblolly pines. Both are composed of identical molecules, yet they are not the same organism.
Perhaps on some abstract plane it is somehow true that all living things are the same organism. But, we must live our lives out here in the real world, where categorizing creatures and other entities is important.
Another example: There is more variation within the species Canis familiaris, than there is between it and the Timber Wolf, Canis lupus.
Now, if one encounters a growling Canid baring it's fangs, should one make no distinction, and therefore take the exact same action, whether it be a Chihuahua or a Timber Wolf?
Thank you,
Amos Behavin

I'm thinking that was bad grammar. He didn't mean we were all one single individual organism, but one TYPE of organism. That is what the discussion was about - TYPES (groups, classifications, etc) of organisms.

Maybe on some level we all are the same type of organism. But, please consider the example of the Chihuahua and the Timber Wolf. If one encounters a snarling, hungry Timber Wolf, should one say "Oh well, that organism is fundamentally no different from a Chihuahua"?

Species do in fact exist.

Species do in fact exist. Members of the same species are capable of interbreeding and producing fertile offspring. Where's the confusion?

Scroll back a couple of pages. Not all animals in the same species can breed and some not in the same species can breed.

 

[O Great One]

Any examples?

If two animals can't interbreed, why would you conclude that they're members of the same species? Conversly, If two animals can interbreed why would you conclude that they're members of different species? Can you give a specific example?

I will agree that a species concept is useful, and can be justified, bioligically, ecologically, etc.
My previous statement merely said that the article posted proved absolutely nothing. Of course there is debate in the scientific field about "race", but those that vie for biological race are wrong. Thats my opinion, which is based on observable biological facts.

amos: please answer...

What would make me white. biologically. You have neglected to give hard answers about what makes a person "white" and what makes them "black", if those are two of the main races there are...
also, if I am a white american, shouldn't that make me genetically closer to a german, than to an african american?
thanks!

Or even better, it hardly matters because its all made from protons neutrons and electrons. Nothings changed right?

You don't get it though. Have you thought about the biological tree of evolution in its four dimensional aspect? Just take that moment to think about it. And you will notice that IT is a creature growing (in some aspect).
It is true, that there is no distinct line between blue and red, but that doesn't mean I can't generally tell the difference between them. It is also true that there is no distinct line between the ocean and the beach. But that doesn't mean I can't generally tell the difference between the ocean and the beach. There is no distinct line anywhere in biology, but that doesn't mean we can't recognise things as being different.

This is all important to remember because people get so damn caught up all the time in trying to distinguish where we should draw line x. As if its a vitally important line to be drawn. Maybe it is important...but asking where it lies, as if it actually exists, is simply a mistake of understanding. Lines to not exist in nature. Lines are created by humans to make our lives easier.

There is no distinct line between being a human and being an ape ancestor...Sure, you can tell them apart, but at no point can you say 'Ah huh. Thats where they seperate.' Because such a point can only ever be created by humans, for our own wishes...not because it actually exists.
