The Red Queen
(7/10) Matt Ridley, author of
Genome, continues his explanation of genetics and genetic theories. The book is split roughly into two parts. In the first, Ridley explains the concept of the “Red Queen” hypothesis in evolution and describes some of the biological debates where it has contributed. In this first half, his focus is largely on non-human animals; birds, bugs, and non-human apes are major players. In the second half, he turns to humans, discussing what the Red Queen theory may imply or explain about human behavior and (especially) human psychology.
In keeping with this bipartite structure, he espouses two major conclusions, though he is very careful to present many different sides and arguments in each debate he examines. The first is that the major reason that many species have two (rather than one, or thirteen, for example) sexes is that sex is a response to a Red Queen race between parasites and hosts. The major point of the second half is that human intelligence may be the result of a similar race – but among humans. The implication is that intelligence is an elaborate, sexually selected fashion.
While these are the core ideas, he looks at a number of different viewpoints to come to them, and he admits freely that they may be either wholly or partially incorrect. Nevertheless, they’re fascinating ideas. This, along with his scrupulous coverage of varying perspectives, saves the book from at times unbearable cutesiness. He may be trying to make genetics more interesting for non-scientists, but I found many of his tangents far less interesting than the actual information.
