Evolution: Why Sex?

Program Overview

|
|
In evolutionary terms, sex is more important than life
itself—without progeny, we are evolutionary losers. Sex fuels
evolutionary change, by adding variation to the gene pool and
eliminating unsatisfactory traits. This program looks at the endless
variety of sexual expression and the powerful hold sex exerts over
almost all living things. And it explores how the need to pass on
our genes has shaped our own bodies, minds, and lives. Some
scientists believe that art, literature, music—in fact all of
human culture—may be the ultimate result of our sexual drives.
