Synopsis by Mark Deming
This documentary examines the phenomenon of extinction, where creatures that once roamed the planet in large numbers suddenly cease to exist. Leading scientific minds explain their theories on this step in the evolutionary ladder -- why certain animals become extinct, how their disappearance comes about, and how their absence impacts the environment.
