Question :

Why is the advent of reproductive isolation important from
an evolutionary point of view ?


Answer :

Reproductive isolation increases the mutation rate.
Reproductive isolation may slow reproduction.
When the organisms comprising two populations of a species can no longer interbreed, the flow of genetic material between them stops.
It is not important from an evolutionary point of view.

Mutation
Sterilisation
Fertilisation
Radiation
