But at the time with Jane Goodall, she had provisioned the chimps so that they would get used to her.

So she had kind of like put bananas out so that they would get used to her presence.

And so there was a lot of criticism.

Oh, you caused all this aggression by putting this high value resource in the middle.

So there was some skepticism about whether this was like really natural.

But this is completely natural.

Why?

Just no one knows?

No one really knows, yeah.

What's really interesting and cool about gorillas is we've been able to show that it's not like that at all.

So we have families that fission, and when they come back together, they can be aggressive, particularly like if they're in their most prized part of their range.

But for the most part, they'll come together, they'll play, they'll interact with each other.

And this can be 10 years after a split.

So a lot of the composition has changed.

And so I think chimps are really interesting for looking at more of the warfare side of humans, and gorillas maybe more for this kind of multi-level society where you can maintain relationships

even if it's not in your core family group that you're with on a day-to-day basis.

Yeah.

If we don't see the genitalia of a baby gorilla right after it's born because they're so fuzzy, we generally oftentimes don't know until they reach 10 or 11 if it's a male.

Because males and females are the same exact size in gorillas until eight.

And then their growth charts really diverge.
