Patagonia In the Footsteps of Charles Darwin 3D 2012 This documentary retraces Darwin’s legendary journey through Patagonia. Viewers see penguins, glaciers, endless pampas, and herds of guanacos. Whales appear off the Valdez Peninsula. Ancient beech forests seem to jump out of the screen. The film explains how these ecosystems inspired the theory of evolution. The 3D format creates the feeling of icy Andean wind and seabird cries.
