Transcript

all right we're gonna take it back to the ancient times now this next researcher works on fossilized mastodons see hmm this next speaker is like straight at Jurassic Park she collects woolly mammoth parts and she grinds their bones to make her bread cuz she's looking for those ancient DNA threads oh not to clone a mammoth no one panic she's trying ...
