Should We Clone Neanderthals ?

In summary: I wouldn't bet on it.Interesting article - technically and ethically. I don't think it's ethical but should we do it? Heck yes! I'm curious. If we clone Neanderthals, it's likely that there will be errors in the sequence. So the ethical question is, would it be ok to clone something (that we should consider a human being for the most part), that we know probably has errors in the sequence and it would be unkown how those errors might manifest themselves?

Interesting article - technically and ethically

We should be able to clone both homo sapiens and neanderthals.

I'm wondering how do they know that they have 100% Neanderthal DNA and that it's even 100% in the correct sequence. Just because it was 'painstakingly' sequenced doesn't mean it's the correct sequence.

It would be worth it just to watch the ACLU, Congress, The Supreme Court and churches fight for turf. :yuck:

I don't get it. When I watch TV I have a feeling they are all around, so what is the fuss about?

With no actual Neanderthal reference genome sequence, there are bound to be a number of errors in this sequence. So the ethical question IMO is, would it be ok to clone something (that we should consider a human being for the most part), that we know probably has errors in the sequence and it would be unkown how those errors might manifest themselves?


On another note, this part made no sense to me:
Although most of the Neanderthal genome sequencing is now being done by the San Diego-based company Illumina, the Max Planck Institute initially chose 454 because it had come up with a way to read hundreds of thousands of DNA sequences at a time.
...because the Illumina sequencers get tens of millions of sequence reads per sample and over 100 million per run. More likely they chose 454 for the longer read-lengths.
It must have just been a confused reporter that really didn't understand. :smile:

I wonder how well something separated by 30,000 years of evolution would fare in the modern world. Would modern viruses just eat it alive? Or would they be completely ineffective because they didn't co-evolve? Is 30,000 just not long enough for it to matter?

You need a lot less separation than that - ask native Americans vs smallpox.

Making Neanderthals - so easy a caveman can do it! :tongue:

Yes, very interesting!

Both the technical details and the ethical implications are beyond what I would be comforable commenting on.

I will say that this could be the basis for a great science fiction book - maybe even a trilogy that spans centuries. I can imagine the scenario where homo sapiens recreate the race of Neanderthals, but underestimate their intelligence and their aggressiveness. The Neanderthals learn the evolutionary history which has homo-sapiens surviving their ancestors. They then resolve to "set things right". The struggles lasts for centuries, with the ironic conclusion of the final book establishing Neanderthals as the master race and homo-sapiens as an extinct species.

Speculating on a biological/evolutionary note. It seems to me that the human invention of cloning (if perfected, that is) has implications in the subject of Natural Selection. Long dead species which now somehow become curiosities to living humans, have an evolutionary second chance, so to speak. A species that offers human benefits of some type (medical, chemical, learning potential) or those that just seem interesting (cute or exotic) may have found a shortcut around the environmental changes that "did them in". Species no longer need to survive through the eons, provided some of their DNA remains intact and some intelligent species evolves and learns how (and finds them interesting enough) to clone them.

Last night, I saw that the Truman Show was on TBS. For some reason, it reminded me of this thread. If we cloned Neanderthals, would we put them into a synthetic environment and let the world watch?

If you want to see people who are 30,000 years away from you, look no further than aboriginal Australians or Polynesians. (Except for residents of Easter Island: those are probably descended from South Americans and therefore they are a bit closer.)

True Neanderthals are likely separated from us by a period of time that's at least an order of magnitude larger.

Of course, no one really knows for sure if the genome that was sequenced by MPI/454 is that of a true Neanderthal. Since it's 30,000 years old and it is from an area that was already populated by Cro-Magnons at the time, it's entirely possible that there are some traces of Cro-Magnon DNA in there too.

Thanks mgb-phys.:smile: I love archaeology, and I've located an excellent video that explains indepth some of the information that the neanderthal article touched upon.

The Neanderthal Genome Project - Svante Pääbo of the Max Planck Institute joins Cold SpringHarbor Laboratory's Dave Micklos to discuss the Neanderthal genome project.

Science/AAAS also has published a Special Feature: The Neandertal Genome

In the 7 May 2010 issue of Science, Green et al. report a draft sequence of the Neandertal genome composed of over 3 billion nucleotides from three individuals, and compare it with the genomes of five modern humans. A companion paper by Burbano et al. describes a method for sequencing target regions of Neandertal DNA. A News Focus , podcast segment, and special online presentation featuring video commentary, text, and a timeline of Neandertal-related discoveries provide additional context for their findings.

[Note: The papers by Green et al. and Burbano et al., as well as the special presentation and podcast, are free to all site visitors.]

Also please take note from one of the articles:
Paleogenetics:
Cloned Neandertals Still in the Realm of Sci-Fi
Elizabeth Pennisi

Science-fiction writers have been resurrecting Neandertals in novels for decades, imagining what it would be like to see and communicate (not to mention mate) with another species of human. So since the idea of sequencing the Neandertal genome became more than a glimmer in a paleogeneticist's eye, some have asked, "Could we, should we, would we, bring this extinct human species back to life?" After all, biologists are trying to bring back the woolly mammoth by cloning. But for both technical and ethical reasons, experts say, bringing back a Neandertal is a pipe dream.

What would we really learn anyways? We have their bones, we know what they looked like...

Sure, we could try to learn how intelligent they were, but is that worth the huge ethical issues we'd create? I think probably not.

What is cloning and how does it work?

Cloning is the process of creating an identical copy of an organism by using its DNA. This is achieved by taking the DNA from a single cell and inserting it into an egg cell that has had its own DNA removed. The egg is then implanted into a surrogate mother where it will develop and grow into a genetically identical organism.

Why are scientists considering cloning Neanderthals?

Scientists are interested in cloning Neanderthals because it would give us the opportunity to study and learn more about our evolutionary history. By cloning Neanderthals, we could potentially answer questions about their behavior, physical characteristics, and how they interacted with other human species.

What are the ethical concerns surrounding cloning Neanderthals?

There are several ethical concerns surrounding cloning Neanderthals, including the potential exploitation of a vulnerable species, the possibility of creating a being that is not accepted by society, and the impact on the environment and existing species. There are also concerns about the potential physical and psychological well-being of the cloned Neanderthal.

What are the scientific challenges of cloning Neanderthals?

One of the main challenges of cloning Neanderthals is the lack of complete DNA samples. While scientists have been able to extract some DNA from Neanderthal fossils, it is not enough to create a complete genome. There are also technical challenges in the cloning process itself, including finding a suitable surrogate mother and ensuring the cloned Neanderthal develops and survives.

What are the potential benefits of cloning Neanderthals?

If successful, cloning Neanderthals could provide us with valuable insights into our evolutionary history and the behavior and biology of this extinct species. It could also have medical applications, such as studying genetic diseases that are unique to Neanderthals and potentially finding cures for them.
