What is your definition of "species"?
Also, is "species" an attribute of an individual entity?
I was using the generic "produces fertile offspring" definition.
Also, is "species" an attribute of an individual entity?
Heck no -- individuals are members of a species, which is almost by definition a group thing.
It does bring up an interesting question, though: if species are separated by an inability produce fertile offspring, is it possible to be "the first of a new species?" If so, then it's not clear to me how that new species could possibly propagate beyond the first member.....
