Either the species benefits in "isolated breeding pools"
OR
"genetic diversity is key for the survival of any species."
There is no contradiction, only your own ignorance.
Perhaps you need a primer in evolutionary biology?

Care to answer the questions presented?
Or is it safe to conclude that you are a genocidal racist?
It is safe to conclude that you are illogical
How is genetic diversity possible in "isolated breeding pools?"
