Question

In some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called ligers. Male ligers are sterile, but some female ligers are fertile. In the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. Furthermore, the solitary behaviour of tigers and the social organisations of lions create behavioural differences.

Applying the biological species concept, the production of ligers reveals that

a) a new species called ligers is forming

b) tigers and lions are actually the same species

c) tigers and lions are seperate species

d) lions are probably a subspecies of tigers.
