Sam Martinez9 said:Fair enough. But how then do you account for modern humans navigating a high-tech society so seamlessly? What is the actual mechanism at play here? Why is today's individual capable of this when our ancestors weren't?
I agree with you there. It’s the same reason smallpox was so devastating to Native Americans. However, my point is specifically about cognitive capacity—about the brain and our reasoning abilities. We have largely neglected that aspect of the evolution.
Well, who's saying they couldn't? It wasn't because they lacked the intellectual or physical capacity; it was simply because the technology didn't exist yet. 😁 If you took a baby born today and dropped them on a deserted island where they were raised by some imaginary "Peterson," how would that child ever learn to use technology from, say, modern USA? Would that question even make sense?
I suppose there is a valid point in asking how humans, living as hunter-gatherers for hundreds of thousands of years, developed the intellect necessary to build today's high-tech societies. That’s a fair question, and it's essentially what I was getting at in my first post. We're talking about hundreds of thousands of years across various Homo species, and maybe 100-150 thousand years for Homo sapiens, during which countless generations lived all over the world. Since they survived and spread globally, it's safe to assume they understood their environment incredibly well. However, I think we tend to use a modern bias when we define "understanding the world," assuming that only our current knowledge counts as advanced. We have engineering, medicine, and various sciences that allow us to build machines, communication networks, and transport systems. But a society from, say, 75,000 years ago probably possessed an equally vast knowledge of nature and survival. The challenges facing an average person back then might have been just as intellectually demanding as ours, especially since the average person today doesn't actually understand most of the tech they use. Most people can drive a car, but they don't really know what's happening under the hood. They know a plane flies and the pilot has a bunch of buttons, but they don't grasp the intricate details that make a commercial jet work. If you break down the daily routine of a typical modern person, the tasks aren't necessarily incredibly complex. They might not be much more difficult than the life of someone 75,000 years ago who had to physically survive through hunting and battling the elements every single day. I guess I'm trying to say that surviving back then was a much harder task than it is now, when we have an entire society and a massive technological safety net to catch us. Back then, natural selection was relentless; those who were more skillful, healthier, and better at providing food and protecting their group were the ones who made it. Intelligence played a huge role in that.
