As I have pointed out on numerous occasions, the natural selection component of TENS is a logical and philosophical hypothesis, not a scientific one. Even Richard Dawkins has reluctantly admitted in his latest book that it is entirely plausible natural selection is not the mechanism by which evolution operates, and since after 150 years there is still no significant scientific evidence that Darwinian natural selection takes place, I expect that it will not be too terribly long before Darwinism takes its rightful place with phrenology, astrology, and other pseudo-sciences. And in the meantime, it is always amusing to see not-very-bright biologists shrieking about how their intellectual superiors don't understand the tremendously complicated concepts to which they are so emotionally attached.
