You mean like farmers saving the best looking seeds from this years crop to plant next year? Isn’t that just quicker natural selection? I’m hoping the white tail deer evolve into a species that learns how to avoid getting hit by vehicles.
No, it’s more like saving the seeds from the best plants, most prolific, largest, tastiest, whatever metric the farmer is seeking to cultivate and then planting those seeds together in their own plot and keeping that seed, and so on.
There is an unfortunate bias that farmers are ignorant and that previous civilizations were also. Thinking that our forbears that somehow managed to survive without the technology we enjoy were less intelligent is so arrogant. How many of today’s elite could survive without it? It’s just so much BS because frankly, agriculture is what supports any and all civilization of any type, whether simple or complex.
And generally speaking, the forces that destroy civilizations stem from the urban follies of the non farming classes more often than they stem from agricultural failure.
