The_Universe said:I have to disagree with the last statement here. Humans and elves cannot be seperate species, because (in D&D, at least) they can produce fertile offspring.
In the real world, we know that horses and donkeys are seperate species because although they can produce offspring together (mules), that offspring is in fact always sterile. In a world without genetic evaluation, that's really the only way to tell.
In contrast, we know that dogs are in fact all one species, even though there are hundreds of racial differences (even variance in longevity). Since any two dogs could produce fertile offspring, they are all one species. Humans and elves can produce fertile offspring (Half-elves), so despite racial differences, they are one species, as well.
One problem. Dogs and wolves are classified as different species. However, they can create fertile offspring. Therefore elves, orcs, and humans can still be different species and still produce fertile offspring. There is precedent.
