Humans are probably some of the weakest animals in history - no claws, no poison, slow, babies take too long to become not helpless. But because of this weakness, they mastered tools.
Wait what is this i don't even
I'm pretty sure that they started mastering tools as their brains got bigger, and then as they no longer needed a lot of stuff because of the tools, certain genes didn't become as important in reproduction (body fur, strong muscles) and others become more important (even bigger brains, which is what actually causes babies to be useless for so long... since they need to be ejected before their heads get too big, unlike animals who are born completely functional).
Why is this still being discussed? It's not as if we know enough about it to begin with, and things are already being ugly.
Translation: why are you guys here instead of one of the dozens of threads I've created?
the most basic hunting method for a human being is walking after a prey animal for a day or two, not letting it sleep or eat, then throwing rocks at it when it passes out;.
That probably evolved into
this.
Wait, what? Humans are nowhere near the top speed bracket in the African savannah. I thought the advantage of bipedalism is that it's more energy efficient. If there's one thing that's useful on short distances it's our manoeuvrability, being able to jump sideway like we can is great for dodging.
"Short distances" were the key words (50m or less). Humans can accelerate faster than most other animals even if the top speed is lower.
That still doesn't look right to me. Big cats, being ambush predators, are all about acceleration. And big cats are what you really need to outrun in our native environment, so the prey animals would be optimized for acceleration as well.
Bipeds have better acceleration *when starting from a complete stop*.
They're also better at like, turning. What good that did against larger predators I'm not sure, maybe we can be evasive that way or in case of us hunting, we can annoy our prey more? Just wanted to clear that up, it's not that we have better acceleration, period. It's just that we can go from zero to... 5? in about zero seconds, while it takes a couple of seconds for a quadruped to get there.
Has anyone considered that our ancestors were better than us in every way? Yes. Even intellectually. We have a larger knowledge base to build new advances upon, and a large pool of varied humanity from which to recruit a shockingly small sliver of truly effective researchers. (Most research is self-indulgent trash.) Having access to the breakthroughs of the past, and access to a few people unlike the rest of us, is not the same as having accomplished everything around us ourselves. Right now, we think we're smarter on average than ever before in mankind simply because we can type broken english into our iPhones. Pushing buttons designed to mask far more complicated systems isn't very hard, actually, and it's what most of us excel at.
Actually, the myth that currently people are dumber because it's easier for them to access information / do operations / use calculators has been debunked several times. What this does, actually, is free more time to invent new things, instead of spending effort on how to find the nth decimal of Pi every time we need it, or spending long hours at a library trying to find a tidbit of info we want.
It's the same logic that says that kids these days are dumber because they use their smartphones all day instead of reading books.
