This is a question about evidence for evolution. It's off topic, but
you guys seem pretty smart about all things biological, and I'm sure
this question would get lost on an evoltuion news group. I think the
main objection to evolution is that, while variation within species
has been observed, no one has ever observed a species changing to
another species. I was wondering if anyone here knew of any studies,
perhaps with drosophila, in which the researchers subjected a
population to a certain environment, which then changed that
population of organisms so that they could no longer inter-bred with
the species they came from. This would be proof of evolution by
natural selection according to the definition of species as
potentially inter-breeding.
