During the Beagle journey, Darwin visited islands, allowing him to
compare island species with continental species. In terms of framing
his theory of evolution, why was this significant? - ANSWER -Because
the island species had both similarities to their continental ancestors
and unique adaptations to their island environments.

offspring would be considered to be a species according to the
