Q

what did darwin think of this

and what was his hypothesis

A

Darwin reasoned that if people could alter the appearance and behaviour of
species, then the environment could have a similar selective effect on wild
species.

Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor.
