What evolutionary concept does the creation of a zorse demonstrate in action?
Answer
A microcosm of reproductive isolation preventing speciation.
The cross between a zebra and a horse, despite their close relation within the *Equus* genus, perfectly illustrates the concept of reproductive isolation. This is the biological barrier that keeps distinct species separate over evolutionary time. Because the chromosomal mismatch inhibits successful meiosis in the hybrid, it demonstrates the incompatibility that exists at the point *just before* full speciation occurs. Observing the sterile zorse provides an accessible, real-world example of the mechanisms that naturally drive the separation and diversification of species over millions of years.
