How do you like dive in to try and, you know, analyze that study or analyze that kind of behavior?
And you can't really do it with humans because you can't really ethically put humans in in like unsafe situations.
You can't say let's put a human in an unsafe situation and study what they do.
Right.
Right, exactly, right?
So you wouldn't ethically be allowed to put a chimpanzee in an unsafe situation, but you can watch them climb trees and jump from tree to tree.
And so that's what they did here is they looked at 100 individual chimpanzees aged 2 to 65 and watched them –
climbing around and taking the risks of jumping.
Like sometimes when they're climbing, they do it really methodically and slow.
And sometimes when they jump from place to place, they'll literally like let go completely and just aim for another branch.
And they found, what they found is that the youngest ones do the most risky things.
So what they concluded was that – so for in humans, it peaks in teenage years.
That's when we're doing the most riskiest things.
But in the chimps, it peaks the youngest.
The youngest ones are doing the most risky stuff, and it slowly goes down over age.
And they think the reason for that is –
chimpanzee parents are just less able to, once the chimpanzees get old enough to start climbing on their own, then they just, the parents just sort of lose ability to protect them.
And so right away they start doing really risky stuff and they slowly learn and get better.
Whereas in the human world, we like helicopter parent our kids all the way up until teenage.
And then at the teenage years, they go to high school and they really, the supervision drops way down and they're starting able to just be out in the world by themselves and they start doing stuff.
