"Of the 7,000 estimated non-native species present in North America, approximately 1,000 are invasive. Clearly, invasive species are in the minority, but their small numbers don't keep them from causing billions of dollars in economic and ecological harm each year. Policymakers and ecologists continue to try to figure out which species might be harmful, which invasive species are doing the most damage, and which of these might respond best to eradication...

Contents include: "Principles Of Sexual Selection",...

This episode interweaves the drama in key moments of Darwin's life with documentary sequences of current research, linking past to present and introducing major concepts of evolutionary theory. It explores why Darwin's "dangerous idea" might matter even more today than it did in his own time, and reveals how science might be used to explain the past and predict the future of life on earth.
