Mammoth blood

I thought this was an interesting story about researchers who used Woolly Mammoth gene sequences to recreate their blood proteins - finding out that they had a variant form of protein in their blood enabling their blood to carry oxygen at much lower temperatures than living creatures today.

a quote from the article:

"It has been remarkable to bring a complex protein from an extinct species back to life and discover important changes not found in any living species," said co-author Alan Cooper, director of the Australian Centre for Ancient DNA at the University of Adelaide.
