thats not an argument just a comment sorry

also "doing it for practice"

we all know you're gay jannet

It's a specifically different behavior. Like a chimp that mounts another male as a dominance display will otherwise behave in a heterosexual manner. Our species is weird in that individuals will continue to engage in that behavior exclusive to reproductive sexual expression. Other primates do not do this. Even non-primates like those "lesbian" birds? They cheat with male birds.

That's how they reproduce.

This is, on the whole, not the strangest thing about humans. Like running is really really unusual....

other animals run tho

No, they really don't. Running is different than galloping.

what about the bipedal dinosaurs

Well they're the same general principle just with bipedal versus quadripedal locomotion.

Like you basically are leaning forward then, while falling, pushing yourself against the ground for propulsion. Dinosaurs had essentially avian physiology it's a different thing. There's a great CARTA lecture on this let me see if I can find it....

doesn't seem all that different

plus all animals would be falling mid stride

There is also a lean for quadripedal locomotion for galloping. It's natural to account for the applied force. They're just not as pronounced as bipedal human running.

Think this is it:

Humans dominate long distance running

Short distance not at all

And yes, galloping and running both involves airborne period.

Humans absolutely lose sprinting.

Yeah we actually outpace quadrupeds for distance.

But horses do real well at long distance.

However for most quadrupeds humans do have superiority in long-distance stamina.

Not as well as humans after a certain distance. We think that was a large part of early hunting. That while short-term we could not outpace herbivores over a longer stretch hominid groups could run them down.

i don't think exhaustion hunting was really that big

waste of energy

Oh it was huge.

humans on a tight energy budget as is with our brains

no need to waste it running long distances at max

Cooking solved the energy budget problem.

Like native American Bison hunting was pretty much all just endurance hunting. There's a large upfront cost in KCals but thee payoff is huge.

Yes, a Bison would provide a massive caloric payoff. Tasty, too.

Our digestive system is adapted to running. Like the differences in our intestines from other primates. Cooking is a huge part f that. This is something we have data on. Women who take on the raw-food diet do not have estrus half the time because without cooking we cannot digest enough energy to reproduce. We are some weird weird monkeys.....

still am not sure how much humans would have relied on exhaustion hunting in particular, since even aboriginals developed ranged weapons, as did every other group of humans

obviously though long distance running would have been helpful for long distance migration and so on

whoop he actually mentions that, that people stopped really doing it after inventing projectile weapons

Ranged weapons are good but we're talking about flint tip spears here not a modern compound bow or even a recurve that can one-shot a deer. So even on a good hit you're going to have to track the game as it bleeds out. Now if you have a whole tribe of hunters and you can run down a whole herd of prey the payoff in calories gained for the investment is much higher.

and i bet they were actually pretty accurate with those spears

This also contributes to human eusociality. There is no way for a hunter to eat an elk or a bison before it goes bad. Even with his extended family. But if you store the meat in the stomachs of other families who might return the favor it does not go bad and it contributes to your survival.

And yeah I am going back a few millennia here. Even the Sentinel Island tribe who broke off, what? a few thousand years ago? Still have non-recurve bows. A much higher tech than most of human history.

you don't need bows though even

lot of people had spear throwers, abos used curved smoothed knotted throwing clubs
