But for the "intelligent nudge" theory to really work, wouldn't we need to see the advent happen throughout the globe at a similar time?
Much of Africa still lived as hunter-gatherers, except for the areas near to the Fertile Crescent and in the far South, and it took Asia another two
millenia to catch up to the Europeans and Fertile Crescent farmers in agriculture (if this article is acurate).
It seems likely that two basic conditions of agriculture had not been met: either the environment wasn't conducive to farming or the culture wasn't.
This doesn't discount your theory though! It could have been "planned" that humans wouldn't start large scale farming until these time periods.
There's quite a few possible factors involved here. We know the human brain has continued to evolve through time and that even now that natural
selection doesn't play near the role it used to in our lives, our brains continue to process information faster and faster with every generation. We
know that even though some ideas seem so basic and so necessary that they'd be obvious to anyone, sometimes those ideas never come to life because
we're so wrapped in our current environment that we don't think outside the box (Duh, Newton! Of course what goes up must come down!).
And we know that agriculture is heavily dependent on a suitable environment and a stable culture.
It could be that there was sudden divine intervention into humanity at that time, or it could be that fate hadn't been on our side for the last
400,000 years.
Then one day, someone got bored in the tribe, planted a seed in the ground, and watched it grow. And they thought, "Hmm...let's plant some more!"
Viola!
