Better cross out Steyn :-)
No need. While Steyn makes a few simple-minded offhand mistatements about biology and evolutionists (even Steyn later admitted, "Not my bag, so I kept it short."), that hardly puts him in the same class as someone who would uncritically parrot wholesale large portions of long-discredited anti-science propaganda without doing his/her homework and due diligence, in a book which presents itself as a well-researched tome.
But in any case, yeah, Steyn would be a poor person to turn to for insights into modern biology. Then again, he admits that this is not his best area of knowledge.
