It’s a good thesis, worth investigating, so one wonders why he buries it.
(Discourse on natural selection does serve the purpose of arguing with vicious evangelical fundie chauvinist pig types, which atheist apologists love to do. When they gain converts, the converts are pre-trained in the techniques! See, for instance, John Loftus – who, by the way, is much more readable than Dawkins, whose turgid writing I can barely scan through before tossing it aside.)
