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

2019-04-23 23:57:44 UTC  

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.

2019-04-23 23:58:19 UTC  

yeah or apparently some animals do it for practice

2019-04-23 23:59:00 UTC  

a dominance display can be a sexual preference too

2019-04-23 23:59:10 UTC  

thats not an argument just a comment sorry

2019-04-24 00:00:56 UTC  

also "doing it for practice"

2019-04-24 00:01:06 UTC  

we all know you're gay jannet

2019-04-24 00:02:59 UTC  

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.

2019-04-24 00:03:13 UTC  

That's how they reproduce.

2019-04-24 00:04:12 UTC  

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

2019-04-24 00:06:17 UTC  

other animals run tho

2019-04-24 00:07:10 UTC  

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

2019-04-24 00:07:35 UTC  

what about the bipedal dinosaurs

2019-04-24 00:08:25 UTC  

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

2019-04-24 00:09:05 UTC  

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....

2019-04-24 00:09:54 UTC  

doesn't seem all that different

2019-04-24 00:10:04 UTC  

plus all animals would be falling mid stride

2019-04-24 00:10:17 UTC  

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.

2019-04-24 00:10:31 UTC  

Humans dominate long distance running

2019-04-24 00:10:38 UTC  

Short distance not at all

2019-04-24 00:10:41 UTC  

And yes, galloping and running both involves airborne period.

2019-04-24 00:10:50 UTC  

Humans absolutely lose sprinting.

2019-04-24 00:11:00 UTC  

Yeah we actually outpace quadrupeds for distance.

2019-04-24 00:11:05 UTC  

But horses do real well at long distance.

2019-04-24 00:11:43 UTC  

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

2019-04-24 00:12:16 UTC  

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.

2019-04-24 00:12:36 UTC  

i don't think exhaustion hunting was really that big

2019-04-24 00:12:51 UTC  

waste of energy

2019-04-24 00:12:55 UTC  

Oh it was huge.

2019-04-24 00:13:02 UTC  

humans on a tight energy budget as is with our brains

2019-04-24 00:13:09 UTC  

no need to waste it running long distances at max

2019-04-24 00:13:17 UTC  

Cooking solved the energy budget problem.

2019-04-24 00:13:49 UTC  

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.

2019-04-24 00:14:15 UTC  

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

2019-04-24 00:16:47 UTC  

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.....

2019-04-24 00:31:14 UTC  

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

2019-04-24 00:31:58 UTC  

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

2019-04-24 00:36:50 UTC  

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

2019-04-24 00:36:59 UTC  

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.

2019-04-24 00:38:42 UTC  

and i bet they were actually pretty accurate with those spears
