all modern cows trace back to ONE single herd.

So apparently, after lots of fancy genetic testing

which I'm sure involves a lot of people in
stark white gowns holding Erlenmeyer Flasks

ALLLL COWS have been traced to
ONE SINGLE COW FAMJAM.

The Abraham of cows?!!

...Noah's Ark???

HEREEEE for more fancy Chem-geek mumbo-jumbo.
