IN THE year of Charles Darwin’s double anniversary—200 years since his birth and 150 since the publication of his masterwork, “On the Origin of Species”—taking a potshot in print at Richard Dawkins must have looked like an irresistible idea. Darwin’s champion in his lifetime, Thomas Huxley, was known to many as his bulldog. Mr Dawkins, his modern champion, has been dubbed his rottweiler, a reflection of his uncompromising defence of both evolutionary theory and the atheism he thinks is a necessary consequence of it. What better way to sell a few books, then, than to attack the man whom many see as Darwin’s representative on earth?Mr Dawkins famously draws fire from religious fundamentalists, and also from less than fundamentalist critics who, nevertheless, seem to resent a scientist daring to question revealed belief on the basis of empirical data. But he also has his critics within biology, and Fern Elsdon-Baker presents herself as one of these—a true believer in evolution who, nevertheless, thinks Mr Dawkins has got the details wrong—or, at least, only half right.She spends the first part of her book trying to set up her argument with an exhaustive history of evolutionary thought, both pre- and post-Darwin. This is interesting in as much as it shows how such thinking has changed over the years, but her real purpose seems to be to create doubt in the reader’s mind about whether selection at the level of the gene is the only mechanism of evolution, which is what Mr Dawkins and his fellow selfish-geners believe.
