Is there anything that's favored evolutionarily? Can we say, well, it would be better if a species only had monogamous relationships, long-term relationships, or what would you say? (laughs) A- a large number of two-second relationships?

(laughs) They're all favored evolutionarily, which is why they exist, but it- it- the kind of boring ecological answer is that it depends on the distribution of food, and it depends how many females can live in a group.

And how many females can live in a group determines how many males can be added to that group.

So if there's enough food for just one animal, then a female has to live on her own.

She might- or she'll have her kid with her, but no one else.

If anyone else tries to join her, make a group, then there wouldn't be enough food.

It does get more complicated than this, but that's the basic.
