Two populations, P and Q, live in different habitats. Their offspring retain different body shapes when raised in identical conditions. Crosses between P and Q produce fertile offspring.
A researcher concludes that the populations have inherited differences and are already different species.
Which evaluation best fits both results?
The first conclusion is supported by persistent differences; the second is contradicted by fertile offspring.
The first conclusion is contradicted by identical conditions; the second is supported by persistent differences.
