Re: Evolution in action

This is again some poor examples of "evolution happening", but when there are no actual examples, I guess you have to cling to whatever you can find, right?

Environmental influence changing size and musculature of animals is common enough. This is hardly evolution but environmental influence. Show me a case of an environmental situation causing a significant structural change and we have something.

And as for butterflies... talk about chasing butterflies! Playing fast and loose with the definition of a species is the only reason you have a "different species" through "hybridization". If a species arises because members that share certain characteristics are reluctant to interbreed with members of another "species" with different characteristics (but are otherwise completely genetically compatible), then we might as well argue that Koreans, the Japanese, and the Chinese are "different species", and that social taboos that they share in common against procreating with one another are "genetic".
