Do/did you hate your bio courses?

  1. Mar 9, 2012 #1
    I'm just curious. Have any of you been frustrated because of your biology courses? I take CP Biology because I may be going into medicine and one of the only reasonable gripes I've had was that to meet California standards creationists have to learn the theory of evolution. My teacher understands his class may feel differently about how humans came - I think he himself believes we were created by a god. My main argument is that students should have a Constitutional right to refuse to learn about anything that is contrary to their religious beliefs and still be able to get a good grade.

    That's my personal gripe. What's yours? That you had to learn plant biology? Just remember that while knowing plant biology won't necessarily help you unless you're thinking about being a gardener or a florist someday, our understanding of genetics was torpedoed by a few pea plant experiments.

    I greatly enjoyed my Biology class last semester. I took General (University) Biology and Honors Biology Lab. I'm glad that we didn't waste our time studying evolution or even a phylogenetic system. We had to rush just to get through all the cellular components that we covered. I got to extract and purify canine DNA, amplify it in a PCR machine, clone it in bacteria, then have it sent off for sequencing. I learned a little about how to use the NCBI's genome database. So, I got to do a lot of fun things. However, if we had covered evolutionary theory, I would have considered it the same as studying Greek mythology. I don't have to believe the system to learn or understand it.

    You shouldn't get a good grade in biology if you don't understand evolution. Evolutionary theory is the foundation of biology. Period. If you don't understand this then you haven't really learned biology and you shouldn't pass the class.

    Religious beliefs are just that, religious beliefs. They are not science, nor are they on the same footing as science for explaining our world. If you can't hack learning about evolution and passing biology then medicine probably isn't for you. If you think that isn't important for medicine then think again. The first year of medical school you spend countless hours dissecting human cadavers, on which you will find the thumbprint of evolution. Understanding that anatomy and where it comes from is important to understanding pathophysiological processes that occur in the human body.

    Yes we have a word for this; ignorance. Why is it, do you suppose, that the Taq polymerase you used could amplify canid DNA?.......
  6. Mar 10, 2012 #5
    I suppose we could use Taq Pol on canid DNA because DNA is DNA, whether in a bacterium or in a dog. Chemical compounds work similarly in similar environments. This is just basic chemistry.

    Even by your standards, that could only vaguely be true. You know that the phylogenetic tree is subject to revision at any time, as it has been several times even in the last few years. You know that new discoveries frequently change the depiction of evolution at all but the most abstract levels. It is only in this generalized form that evolutionary theory even has any application in medicine.
  8. Mar 10, 2012 #7
    But there isn't any reasonable reason to think that at the microscopic level, they are all fundamentally alike is there; unless you take evolution into consideration.
  9. Mar 10, 2012 #8
    I don't know or really want to know about your beliefs regarding the age of the earth or the origin of species. However, do you deny that evolution is occurring now and can be observed?
  10. Mar 10, 2012 #9
    Why would I think that adenine, guanine, cytosine and thymine would behave differently in one organism as in another? They *are* microscopically alike, because they are chemically alike. Evolution has nothing to do with it.
  11. Mar 10, 2012 #10
    Oh, sure, for some definition of the word, evolution is occurring and can be observed.
  12. Mar 10, 2012 #11
    I guess the argument will be what is the practical application of theory of evolution ?. I have heard several similar of these type of questions . I f an analogy is taken from physics, general theory of relativity has helped to increase the accuracy of GPS by factoring in for the time dilatation or understanding lasers helped to build lasers having a lot applications.

    And yet the very same organisms (bacteria or viruses ) have the ability to infect us. And don't tell me it was designed to infect us.
  14. Mar 10, 2012 #13
    Haha you're right. But that's because you already know that it is DNA which is the genetic material. But why is it only DNA and not any other macromolecule? It could reasonably expect to have different sorts of genetic material right?
  15. Mar 10, 2012 #14
    I don't understand what you are claiming. To the best of my knowledge, T. aquaticus is incapable of infecting us.
  16. Mar 10, 2012 #15
    For a few decades, many scientists expected that the carrier of genetic information would be found to be proteins. After all, pretty much everything else in all organisms revolves around proteins. Yet, we have never found any organism whose genetic information is carried that way. Some viruses do use RNA, though.
  17. Mar 10, 2012 #16
    And your point is?
  18. Mar 10, 2012 #17
    I was answering your question, though I don't understand the point you were trying to reach.

    Unbelievable, that is not how education works. Religion beliefs do not stand above scientific theories, in order to pass a scientific class one should learn the scientific theory.

    I once had a strongly religious student do an internship with me, his personal beliefs stood in his way in completing the biology internship. Because of that he had to quit his University education. How sad is that? The student had himself to blame and no-one else.

    If you think studying the phylogenetic system is a waste of time, then you really have a large blind spot in your knowledge. Even if you do not belief in evolution, the information on how related different organisms are is still important. Especially when studying medicine.

    "Relatedness" is in terms of best human judgement, not any purely objective measure. That's why a board has to review how the tree is arranged; the phylogenetic tree is a judgement call.
  21. Mar 10, 2012 #20
    What about genetics ? does genetics prove relatedness in your opinion.

    I was not talking about t aquaticus . I was talking about the basic building blocks of life are the same for most organisms (i.e. DNA, RNA, etc ). which favors strongly for common descent.
