Selection determines who lives, who dies, and who passes traits on to the next generation. The process plays a critical role in our daily lives, yet it is one of the most overlooked -- and misunderstood -- concepts ever described.

The powerful urge to pass our genes on to the next generation has likely changed the face of human culture in ways we're only beginning to understand. A film for both Darwin Day and Valentine's Day!
