If an organism was reproducing asexually, what’s the theory/reasoning behind why they’d develop different sexual organs to reproduce sexually?

While we’re in the ballpark. . .What are some of the best examples of creatures who are presently in the middle of transitioning between species?

Because sex is not only a first rate reproductive strategy that has asexual reproduction beat by a mile as far as the genetic diversity of offspring - it is ALSO a lot more fun.

Bonobo chimps and Pan chimps are in the process of becoming separate species. It is exactly what one would expect if a river changed course a long time ago and ran through the middle of the chimp range. Chimps do not swim so the river was a reproductive barrier - and as is INEVITABLE - differences accumulated in separate populations - with the bonobo being smaller and much more sex crazed than its “cousins” across the river.
