What is speciation?
The formation of new species from an existing species.
How can separated populations accumulate inherited differences over generations?
They exchange few or no alleles, and differences accumulate, including through natural selection in different environments.
How may the phenotypes of separated populations change as inherited differences accumulate?
Their phenotypes may become increasingly different.
When are two populations regarded as distinct species?
When they can no longer interbreed to produce fertile offspring.
