> Conquering new land is deeply embedded into our psyches for evolutionary reasons. The species that's not afraid to do that will probably be more successful in the long run. Conquest of more land is generally correlated with better survival chances.

Overwhelming majority of people stay where they are. Generally humans need huge practical motivation to conquer lands.

Plus, interpreting climbing as conquering lands is super odd. It has more to do with any other sport achievemt then anything else.
