I hate to admit it, but you do have a point here. In
fact, it's worse than you make it out to be...

One COMMON argument against Neanderthal/Modern
interbreeding was that they were two different species,
and different species can't interbreed...

It was a seriously dumb argument even before all the
evidence for interbreeding, but there's an even more
comical example:  The Triceratops Dinosaur!

Presently, the popular belief is that what was at one
time thought of as three separate species are actually
all members of the same species -- only at different
life stages!

And I have used the dog argument myself, many times.
It is undeniably true that, had all our current breeds
of dogs lived 50 million years ago instead of today,
"Scientist" would be claiming that they were all different
species...  and just think of what they would have made
of our mutts!
