Re: Micro vs Macro
Nuggin, I got a couple of real stupid question.
We may consider fossils of three very phyiscally similiar birds to be the same species, even though, in practice, their feather coloration (which would not get preserved) prohibits them from interbreeding since the various types of females are simply not attracted to the different types of plummage.
Does this mean they can't or just refuse to interbreed?
If they just refuse to interbreed why would this be macroevolution?
