Actually, it is falsifiable. Try reading The Darwinian Revolution : Science Red in Tooth and Claw by Michael Ruse. It does a great job of explaining how Darwin came up with his theory in the face of great opposition. It's succeeded because observations support it. Note that a number of other large complex systems are described by science, considered fact, and yet are not reproducible by experiment. For instance, the fact that stars exist through fusion, galaxies are scattered uniformly through the universe, and that the universe is expanding. No experiment reproduces these theories, but they're generally accepted as fact because all observations support the theories that describe them.
