:::::That's what I figured, actually. There are still some major differences between Crichton's anaology is a bit off still though. In the case of dysgenics, there never was anything based on science to truly use it as a word to describe the alterations at a genetic level, especially in human beings. But we have ice core samples and other data that extnd back hundreds of thousands of years, and by all evidence, the CO² levels today are as high as they were during the Jurrassic period. This carbon dioxide level has been increasing at a still not yet fully understood level due to fossil fuel use. IT may be anywhere from 1 to 30 percent. No doubt, humans are not the only reason the earth has been warming now for over 150 years, however, there are few if any scientists that can argue with the observable data, whereby, there was only bigotry to base dysgenics on. I don't disagree with Crichton completely, but think he could have come up with a better analogy than a comparison between global warming and dysgenics.
