"If two creatures can mate and deliver fertile offspring aren’t they the same species?"

I believe that there is a problem in describing "species." I know that horses and donkeys can produce a sturdy work animal called a mule. Mules aren't supposed to be able to reproduce but, from time to time, they do reproduce.

But, in the case of traditional humans and Neanderthals, I believe that one would have to be very drunk to tie up with one of those.

That is something I did not know.

Do you have a link to back the up (I’m not doubting you, I really am curious)

Within the last several days an article stating that Neanderthal/Homo Sapien matings gave contemporary humans especially effective immune systems. So beer gogles may be at work, or it is more complicated than that, if these genetic markers prove out.
