Okay ... so crabs that have shells that look like a warrior are more likely to survive. But they're still crabs! Shouldn't they be something different by now?Dr. Sagan says that viruses have about 10,000 bits of information, bacteria have about 1 million bits, and humans have about 5 billion bits. If the guesses on evolution and the earth's age are right, then it took about 2 billion years to get from bacteria to humans.Evolution is not a linear process, but an exponential one. Take the first bit of evolutionary information as happening in Year 0. So, using the three points (0, 1), (2 billion, 1 million), and (4 billion, 5 billion) and an equation of the form y = e^(bx), a curve that fits well in our era has b ~ 5.58 E-9.The warrior battle was about 1,000 years ago, or x = 3,999,999,000 years after the first bit came into bit-existence. Y = e^(bx) ~ 4,999,972,000. Subtract that from ~ 5 billion human bits and you get about 28,000 predicted bit changes in crabs - and all species, if evolution is still going on - between the Japanese warrior battles and today, or changes about 3x more than in an average virus. Such a change is easily detectable and find-able.Yet the crabs are still ... well ... crabs, and not super-virus-crabs or whatever. Same with everything else. Flies that develop an immunity to poison are still flies and not super-virus-flies (or whatever).Why are the crabs still crabs? Natural selection exists, but there's been no crab-evolution - no crab-advance to something higher or even crab-change. Sure, my base might be off, but e is a very low base, about 2.7, and real evolutionary velocity could easily have something much greater - 4 or 10 or 2,000 - which would only make the non-advance harder to explain.
