> Do explorers survive better than people who migrate to new locations with their families, or something?
No, they die far more often. Because they enter unknown risky situations.
Humans explore in search of new lands and resources, and in search of safe paths.
When they take the more vulnerable members of the tribe, they generally have a better idea of where they're going, what the path is, and what risks are involved.
If a path is too dangerous then they don't tend to take pregnant women and small children.
So because it is primarily adult or adolescent males that go on the more risky adventures, they're the ones that have the costly adaptations required to maximise the likelihood of survival.
