Oh brother. If there was ever such thing as a non-story, this would be it. I mean come on....do these scientists really think we're that stupid? This is no different than observing that Africans, for instance, have developed darker skin because of their sunny location near the equator. Lots of Germans nowdays have blonde hair and blue eyes because of Hitler's perceived notion of beauty. The Danes are all tall and white. The japanese are all short. Koreans do well in school. Mexicans digest pig intestines better than us white people do. What's the freaking point? Obviously humans have changed characteristics over the generations!...otherwise we'd all be clones. Heck, now they're even saying that there's some new mysterious "gay gene" floating around. This story is not worth the webpage it was created on. It's amazing what these atheist scientists will come up with to somehow back up and propagate their personal agendas. This honestly is the stupidest story I've read in a long time....and Karlin, you soaked it up like a sponge.
