Can We Resurrect the Dinosaurs? Neanderthal Man?

YouTube Description:

Dr. Kaku answers the question of whether it is possible to resurrect the dinosaurs by "turning on" their ancient genes? Moreover, now that we have also sequenced the genes of the Neanderthal man, at some point in the future it may be possible to bring him back. And then of course, if a young Neanderthal boy is born then the question is where do you put the boy, in a zoo or at Harvard?

The range among modern human individuals is greater than the distance between modern humans and Neanderthals.

So resurrecting Neanderthals wouldn't tell us anything we don't already know about human behavior. (They'd like instinctual activities and not like to read etc.)

I have a bit of an issue with Dr.Naku and his musings about biology, especially after seeing him butcher and mangle the theory of evolution and say that humans have "by-and-large" stopped evolving. Which is bullshit. (http://bigthink.com/ideas/26647)

I'm sure Dr.Naku is an excellent theoretical physicist, but he has shown that he doesnt really master biology all that well. I have a feeling he does the same thing here. There are all sorts of problems that might not be solvable here. Animals are more, biologically speaking, than a DNA "recipe" that you can simply "put into an egg", there are all sorts of evo-devo that comes in to complicate this tremendously. It is not at all clear that simply sequencing a genome (assumming its a complete and 100% accurate sequencing, which I'm pretty sure it isnt for the neanderthal and mammoth) that comes into play here. In other words, the limitation might not be our technology. Its a bit like the zoom-in-and-enhance-it problem you have in Hollywood movies. it doesnt matter if you have a billion-dollar computer from the year 4350 if the original recording is an old VHS tape of a CCTV recording.

Science isn't 100% or nothing. Creating someone who is 95% neanderthal would still be scientifically useful.


Well, thats not really how genes, genomes and sequencing works. You can sequence a genome 100% , but the accuracy might not be perfect, then you can sequence bits and peices to determine familiarity etc and that might be close to 100% in accuracy. The point is that just because someone says "we have sequenced the Neanderthal genome" that doesnt have to mean that that sequencing is even remotely useable as a cloning template or whatever.

And you cant just make a "95% neanderthal" and expect it to be "almost neanderthal".

The devil, or neanderthal in this case, is in the details, and what we have to work with, regardless of future technology is degraded bits of DNA thats tens of thousands of years old. Again, think about it like a video in recorded in low quality, its not going to be HD just because you have a fancy computer.

I googled this stuff to see if my skepticism was warranted: Here is a quote from one of the people who actually did the sequencing (taken from Wikipedia):

In February 2009, the Max Planck Institute's team, led by geneticist Svante Pääbo, announced that they had completed the first draft of the Neanderthal genome[3] An early analysis of the data suggested in "the genome of Neanderthals, a human species driven to extinction" "no significant trace of Neanderthal genes in modern humans".[17] New results suggested that some adult Neanderthals were lactose intolerant.[14] On the question of potentially cloning a Neanderthal, Pääbo commented, "Starting from the DNA extracted from a fossil, it is and will remain impossible."

So there you have it. Naku is, once again, talking shit, and should stick to his own field of study.

That scientist gave his reason for the impossibility this way: "Paabo said because the Neanderthal DNA was scattered in imperfect fossils, the notion of cloning a Neanderthal was far-fetched." (Source.)


It sounds like he's talking about cloning one individual Neanderthal, rather than synthesizing a Neanderthal genome from many incomplete fossils.

Genomes are just a series of 4 letters... so future tech will only need the complete sequence of those 4 letters. Degradation like a video recorded in low quality doesn't apply... you either can determine which of the 4 letters is in that spot, or you have to get another fossil sample that has that location intact.


Yeah, Naku's value seems to be that he's a nice guy that the public can relate to.
