Call it examples of species in transition.

Try crossing a donkey with an antelope.

Given all the stuff they can each crossbreed with it's hardly unlikely.

Say, Harry, was it survival pressures or sexual selection? I imagine it was the latter because I've been led to believe gene drift happens a lot on Barbadian beaches, especially in high tourist season. Or is it one of those other fancy Greek-rooted concepts you guys are big on?

Speaking of gene drift, are there any dourists in Barbados? Or tourbras? Now that would make an interesting story.

Let them call it a Zonkey. Calling it a Deebra would undercut a century-old adolescent joke by rendering it plausible.

Moo, moo, I love you, I know you're a cow but anything will doooooo.............

"Call it further disproof."

Of what?

It's even worse than Orrin imagines. Occasionally, but not usually, mules prove interfertile with either a horse or a donkey.

It's a continuum, you see.

Sort of like choirs of angels.

It's a species.

You're cute when you're stubborn.

I'm just here in case some non-dogmatist lurkers are around to remind everyone that you are unable to attack evolution (say, rather, biology) on the observations and theories it presents, so you have to torture words.

If you think families are species, you are wise to adhere to the time zone rule, becuase there are places in America where treating all snakes as being the same as garter snakes could prove harmful to your health.

Well, if y'all have given up on the idea of species then we can all get along. I agree there are families.

OJ:

Are Robins and Finches members of the same family?

How about species?

Yes

How do you know?

there's a finbin at our feeder now.

Somehow, I doubt it.
