Natural Selection & Sexual Selection: An Illustrated Introduction | Cornell / National Geographic

How does evolution happen? Through a gradual process called selection. Individuals that are better equipped to survive and reproduce pass those traits to their offspring. These “selected” changes accumulate over thousands of years. We tend to think of natural selection—”survival of the fittest”—but sexual selection works the same way and can be just as strong in shaping how species look and act. Filmed and photographed by Tim Laman and Ed Scholes.

There are currently seventy-two short films in the entire Birds-of-Paradise Project playlist, ranging from 26 seconds to 8:29. In the upcoming weeks, we will present some of our favorites.
