The book begins with an evolutionary account of sex itself, defending the theory that sex flourishes, despite its energetic costs, primarily because a sexually mixed heritage confers to offspring a defensive "head start" against parasites received from and originally adapted to the maternal host environment.
Toward the end of the book Ridley argues that human intelligence is largely a result of sexual selection. He argues that human intelligence far outstrips any survivalist demands that would have been placed on our hominid ancestors, and analogizes human intelligence to the peacock's tail, a trait widely believed to be the result of sexual selection. Human intelligence, he suggests, is used primarily to attract mates through prodigious displays of wit, charm, inventiveness, and individuality. This view of Intelligence is treated at length in Geoffrey Miller's The Mating Mind: How Sexual Choice Shaped the Evolution of Human Nature (2001)

Famous quotes containing the word contents:
“To be, contents his natural desire;
He asks no Angel’s wing, no Seraph’s fire;
But thinks, admitted to that equal sky,
His faithful dog shall bear him company.”
—Alexander Pope (1688–1744)
“Such as boxed
Their feelings properly, complete to tags
A box for dark men and a box for Other
Would often find the contents had been scrambled.”
—Gwendolyn Brooks (b. 1917)
“Yet to speak of the whole world as metaphor
Is still to stick to the contents of the mind
And the desire to believe in a metaphor.
It is to stick to the nicer knowledge of
Belief, that what it believes in is not true.”
—Wallace Stevens (1879–1955)
