It happens.
It’s why there’s a different flu vaccine each year.
It’s how corn came to exist.
It’s why antibiotic resistant bacteria exist.
It’s how these little lizards came to be quite different little lizards in roughly 35 years.
It’s why syphilis no longer has symptoms including “Boils that stood out like Acorns, from whence issued such filthy stinking Matter, that whosoever came within the Scent, believed himself infected. The Colour of these was of a dark Green and the very Aspect as shocking as the pain itself, which yet was as if the Sick had laid upon a fire.” I think the author of the news item put it well: “First, it contrasts markedly with modern experiences with the disease…. Second, it is reasonable to suppose that a sufferer of [these] symptoms… would be unlikely to get a lot of dates.”
How and why evolution happens? Yes that’s a theory. But to ignore evolution altogether is to ignore a law of nature.
In closing: dying for lack of insurance; the recession diet as endorsed by TheStreet.com (way to get to that hard hitting economics and market news there, Jim Cramer must be sooooo proud); OPEC tells the truth, that high oil prices are at least partly because of the weak dollar (which is in turn because of certain Bush Administration policies); young voters more likely to be Democrats; it turns out that of the 53 teenage girls taken from the FDLS compound, 31 were moms or moms-to-be (I think that’s grounds enough to keep the 53 girls away from that place permanently); it turns out that all that hands-on math teaching with “manipulatives” and lots of word problems may be making it harder to learn math; “fat but fit” turns out to be largely untrue after all; and renovated robot rides again.
