Mammoth hair offers new style of research
Study reveals valuable store of ancient DNA in museum samples.
Geneticists have pieced together gene sequences from ten Siberian mammoths, using tiny samples of their hair found preserved in the Russian tundra. The result uses some of the oldest DNA ever pieced together — one of the mammoths had lain in the frozen ground for some 50,000 years.
Comments
Its an indeed good attempt to procure DNA form hairs. But i have a conceptual doubt over it. Hairs are dead parts and grow from the hair follicles. They dont have any living cells in them. I don't understand how can the group of scientists can procure DNA from these dead parts.

Following publication of this interesting result in popular media we can expect that anti-science creationists will insist that this "proves" that the earth is actually young.
This has been our experience following the publication of other projects recovering organic remnants form ancient sources. For a discussion and refutations of creationist misrepresentation of this sort of work see Ancient Molecules Modern Myths, or Dino Blood Redux.
I recommend that all researchers in molecular paleontology become familiar with creationist abuse of their work, and be prepared to debunk anti-science claims.

hey what is the proof that it is not the DNA of any other organism attched or same DNA srech...we have to be emore cautious taking these reoprts very seriously.

Gary Hurd may be right in that such findings will delight creationists and strengthen their beliefs. I, for one, find it incomprehensible why biological findings keep contradicting scientific, i.e. evolutionary, dogmas and expectations. Of course, the researchers may doubt the theoretical models of DNA decay, but isn't that similar to what creationists do when they doubt long-age models?
The data as they are presented to us over the past 5-10 years are not in line with chemical and fysical expectation. Either chemistry and fysics are wrong or the dating techniques. Or both?

Although it sounds really interesting, I couldn't read the full story, unfortunately.

How can they do it. I have never understood it and I will never understand...

i agree with him . "I don't understand how can the group of scientists can procure DNA from these dead parts."
