From Future Pundit:
10000 to 7600 year old woolly mammoth DNA was found frozen in Alaska tundra. So this begs the obvious question: Is the DNA good enough to sequence and use some day to bring back the woolly mammoth?
The work of U of A Earth and Atmospheric Sciences professor Duane Froese and his colleagues counters an important extinction theory, based on radiocarbon dating of bones and teeth. That analysis concluded that more than half of the large mammals in North America (the 'megafauna') disappeared about 13,000 years ago.
