Subject: RE: BS: Evolution as Heresy?
Well, actually new species are popping up all the time. I read that a few decades ago, a huge flock of arctic terns had reached some sort of critical mass and split up. One group migrated east around the northern edges of the continents, the other group migrated west. A sufficient enough number of alterations (random mutations, miscellaneous mixtures, etc.) had taken place in their DNA while they were apart that when they met up again, they could mate, but their mating produced no offspring. Also, some of their markings were slightly different. For mating to take place between substantial numbers of the two different flocks without producing offspring is one of the characteristics that indicated they have evolved into closely related but different species.

In the world's oceans, marine biologists are noting the emergence of new species all the time. Evolution is still going on. But it takes awhile for it to become noticeable by those other than the scientists who are keeping close track.

'Tain't that I'm so smart, I just watch a lot of science programs on television and read a fair amount. I'm sort of a science nut. Always have been.
