In the 4th century BC the Greek philosopher Aristotle traveled to Lesvos, an island in the Aegean teeming, then as now, with wildlife.
His fascination with what he found there, and his painstaking study of it, led to the birth of a new science - biology.

A film that examines Aristotle's discoveries about nature on the island of Lesvos and how they influenced his views on human biology.
