OK, they can't interbred, but they're the same species?

The article didn't say that they couldn't interbreed. It said that they had "changes in courtship behavior."

I suspect that if you lock any species in a jar for 49 generations there will be some who tend to exhibit some deviant sexual attitudes.

Okay, I'll rephrase it....


Is there a creationist tree of life, or list or table, etc., that defines all the species ('kinds') that cannot ever become other species ('kinds')?

The article didn't say that they couldn't interbreed. It said that they had "changes in courtship behavior."

It also said that "positive assortative mating"^* was observed.

You're correct, the two varieties did occasionally interbreed.

So the speciation was only partial.

Maybe we can get the DI to perform the same experiment over 400 generations instead of 40.

Any predictions?

After 4000 generations?

...deviant sexual attitudes...

I don't think it's proper to talk about flies having attitudes. They're not smart enough, at least IMO.

^*A situation in which like phenotypes mate more commonly than expected by chance.

HMMmmm....

This doesn't look GOOD for folks who spend so much time on these threads; either!
