A cool science moment (aren't they all?)

Today in WaPo was a really interesting article about how a bunch of scientists are reconstructing the genome of the woolly mammoth using samples from 20,000-year-old and 65,000-year-old specimens. They are 2/3s done & it seems that this genome varies from modern elephants on by 0.6%, which is approximately half of the genetic difference between humans & chimpanzees. This is a fascinating concept because although mammoths lived in very cold climates, elephants live in very warm climates. So...what were the adaptations to enable this switch? Anyhoo, it's nice to hear of these findings because they raise further inquiry/research & potentially, render profound discoveries that advance our knowledge of life.
