Yeah homosexuality is fairly normal and consistent in human behavior. **There** we do have solid data. While not entirely innate the frequency is at a level over a long enough timeline to warrant that.

i read an article by the bbc once a while ago actually about homos, and they said there is one other species which some of the males are exclusively attracted to other males even when ample female mates are available, and that is the domestic sheep

and the prevalence in said domestic sheep is about 10% (of the males)

Oh yeah we are pretty strange in that aspect. I mean most primates engage in homosexual behavior but we are the only species where individuals do so exclusively. Like when chomps bugger each other it's a dominance display not a sexual preference. Trivers did some really interesting work on this.

yeah or apparently some animals do it for practice

a dominance display can be a sexual preference too

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
