That second article was a real eye-opener, Mr. T.

She and co-author Doug Axe tested in the lab an easier case of evolutionary transition, from one similar but functionally distinct bacterial protein to another -- "evolutionary cousins" of a humbler type. This very minor revolution would require seven coordinated mutations if not more, which in a population of bacteria would need something like 10^27 years.

To put that in some perspective, remember that the universe is only about 10^10 years old. It can't have happened.

The problem of accomplishing the revolution that transforms a chimp-like ancestor into a member of the genus Homo is, of course, worlds and worlds and worlds more difficult. Dr. Gauger cites Dennis Bramble and Daniel Lieberman, writing in Nature and describing the immensity of difference in anatomical features -- the unique gifts that make their first appearance in Homo erectus and Homo sapiens.

Remember we're not talking about what are arguably called spiritual endowments -- the ability to speak, write, do math, do art, appreciate lofty moral and aesthetic ideals, and the rest that science can't even describe much less account for in evolutionary terms. We're just talking about the anatomy.

Bramble and Lieberman count 16 such revolutionary changes and Gauger points out that the transition from our last presumed common ancestor with chimps is allotted only six million years by the standard timetable. This itself produces a defeater for any Darwinian narrative of human evolution:

Each of these new features probably required multiple mutations. Getting a feature that requires six neutral mutations is the limit of what bacteria can produce. For primates (e.g., monkeys, apes and humans) the limit is much more severe. Because of much smaller effective population sizes (an estimated ten thousand for humans instead of a billion for bacteria) and long generation times (fifteen to twenty years per generation for humans vs. a thousand generations per year for bacteria), it would take a very long time for even a single beneficial mutation to appear and become fixed in a human population.

Gauger concludes:

Our uniquely human attributes constitute a quantum leap, not just an innovation, a leap that cannot have arisen without guidance. We are not souped-up apes.


My, oh my, how fascinating.

I think it is really cute when Ann, Doug, and Casey get together and pretend to do science, don't you?

Let's start by fudging a number based on an asexual organism (but no HGT allowed!) and then apply it to a sexually reproducing organism! Wow, evilution is teh disproved!!1!
