What BBN said about it

Chip Darnell · U.S. News AnchorScientists in Siberia have identified a brand new Ice Age mammal, closely related to modern yaks, from bone fragments too small to even show its shape.

Kenji Moonfield · Internet & Trends CorrespondentThey pulled twenty ancient genomes out of those scraps, and that's how they proved it was its own species. They're calling it Yak X.

Chip Darnell · U.S. News AnchorSomebody looked at a pile of crumbs nobody could identify and said, I believe in you. I'm sorry, I'm fine.

Kenji Moonfield · Internet & Trends CorrespondentTwo hundred fifty thousand years to twenty-seven thousand. That's a long run for an account with zero followers.

Chip Darnell · U.S. News AnchorAnd it came from Denisova Cave, where the first Denisovan finger bone turned up in two thousand eight.

Kenji Moonfield · Internet & Trends CorrespondentOne of the researchers, Love Dalén, says it seems reasonable that Yak X was on the Denisovan menu.

Chip Darnell · U.S. News AnchorAw, so it had a purpose.

Kenji Moonfield · Internet & Trends CorrespondentTwenty genomes from crumbs too small to show a shape, and I can't find one charger on my own desk.
