Hate to break it to you, Calvin, but the lead geneticist at Cornell wrote a book on how our genes are failing at the rate of 150 to 500 errors in our genetic codes every generation. (That is one thing that sci-fi like SG1 got right, with an older race literally dying out from cumulative genetic errors. They tried cloning, but it only worked to a certain point.) The cumulative deletarious mutations alone would disprove the notion of evolution— we are devolving at a quantifiable rate. About 15,000 errors have been catalogued and every human has a bunch of them. Only one genetic error that we know of— and it causes sickle-cell anemia— could be thought to be partially beneficial, because it gives some protection from malaria. The only good thing I know of out of the HCERA and PPACA was the elimination of the feeding frenzy on “pre-existing conditions.” It was getting to the point of doing genetic tests to determine who had what “pre-existing condition”, which is like wasting $1000 to save $10 since everyone has them.
