Species is defined not by appearance, but by ability to breed and produce viable offspring with the ability to reproduce. You are in fact totally incorrect on that point as well as the bone marrow point lol
Multiracial patients often have an incredibly hard time finding life-saving marrow matches.
You are incorrect on both claims. Fertile offspring is ONE of the criteria for speciation. Coyotes and wolves can produce fertile offspring. As can all breeds of chimpanzee. And tigers. Yet these all have multiple species.
Another differentiation is overlapping habitats. Well, when you artificially move one species in with another, does that make them magically the same species?
The only difference is a matter of transportation. So if we put all tigers from different places into the same zoo, by your logic they are the same species.
