Imagine it’s 1935, and you’re a Soviet agronomist.

00:04

Not just any agronomist, though. You’re the founder and head of the Lenin All-Union Academy of Agricultural Sciences.

00:11

And among your many accomplishments, your research had led you to  propose that certain crops… like the rye that helped  feed your fellow comrades… were basically an accident.  Humans didn’t domesticate them.

00:24

Thanks to evolution, they domesticated themselves.

00:26

Oh, and your reward for all your hard  work? You just lost your job.

00:38

00:45

But decades after your death, scientists totally got your  back, and proved you were right.

01:09

He did a lot of research trying to find where important crops were first domesticated, and what happened as they spread  to other parts of the world.

01:18

He also basically invented  the concept of a seed bank, and there is a great story about  the one he founded in Leningrad.

01:24

But we don’t have time to get to that, today.
