I don’t think there’s a consensus belief that we deliberately selected for the non-shattering trait. Many think it was more of an accidental process. In a wild field full of shattering plants, harvest is done by threshing the right there in the field and discarding the stalk. Ergo those seeds with the non-shattering property are left on the ground and their numbers are concentrated in the population of the field over time.
Absolutely mind-blowing period. The successive back to africa migrations leading to north east african agriculture, civilisations and trade through that bidirectional route is remarkable.
Wonderful lecture! Loved your balance and pacing of the story. I suppose this means i have to read another crushing volume of prehistory. OMG!! Still, thank you so much. Really enjoyed it.
Thanks Terry, very kind of you say that. I try to get some of Durant's ideas across as well as some of things we’ve discovered since the books were published. Thanks again.
I'm going to speculate that agriculture evolved along side human social organizational capabilities. And that we've been practicing agriculture for much longer than the period we have evidence for, as people were cultivating wild plants. And that the emergence of agriculture is really just emergence of evolved plant species that humans farm.
Given that sedentism predates agriculture, I think it likely that agriculture developed in order to maintain sedentism. A sedentary community can only get so big before the distance to unexploited hunting and gathering areas becomes too far to reach easily.
Yeah it is interesting, I wondered the same thing when I was making the Conditions of Civilization video. I assume that it is because of the geographical spread of the human population at that time.
A leading theory among um .. me and my cat.. as to why other hominids died out was their discovery of Lamarckian evolution, leaving ample room for early homo sapiens to eventually give birth to Darwin and exploit their unfortunate folly.
Love your cat! Your discussion of these chapters is superb and very enjoyable, too!
Thanks willowmcg, very kind of you to say.
thank you for another great video
Superb lecture, Thank you!
Thank you for another great video.

Humans discovered and exploited the driver of evolution -selection.
thanks, very good video.
Love those kitties !

One of the most fascinating things to me, is that the agricultural development started in this interglacial and not Eemian (the previous one)

Is it possible that previous interglacials did not last long enough for human agricultural development?
@@andywomack3414 I think that probably men's evolution has not reached the stage being capable of agriculture
As good as the books!!
Could civilization owe it's existence to the human discovery of evolution?
