Does Reproductive Isolation Lead to Speciation

New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups.

How does reproductive isolation affect speciation?

Reproductive isolation represents a breakdown in the ability to reproduce successfully with sexual partners of another type of organism, and speciation requires a build up of reproductive isolation between diverging types of organism until gene flow is sufficiently rare or ineffective that the entities are considered ‘ …

How does reproductive isolation lead to new species?

Reproductive isolation occurs when a population splits into two groups and the two populations no longer interbreed. When populations become reproductively isolated, they can evolve into two separate species.
