Million-year-old DNA sheds light on the genomic history of mammoths

Million year old DNA sequenced. Impressive.


Iā€™m really impressed the the computational methods have come so far to be able to do this sort of reconstruction.

Yep, same. And the million year preservation of DNA too.

It might not remain the record for long though. It seems Mary Schweitzer and colleagues have found evidence for DNA fragments in dinosaur bones.

So did I until I read that paper. Short of sequencing the evidence they present seems pretty solid to me. Question is how intact it is, if it really is DNA.
