Things You Learned in School That Are No Longer True (Part 2)

Some of the facts you learned in school didn't age well. In Part 2 of Things You Learned in School That Are No Longer True, we count down ten classroom "facts" that turned out to be myths, mistakes or outdated science, and explain what we actually know now. Find out why Viking horns came from an opera costume department, why the tongue map was built on a misread graph, and how Cold War bomb tests helped show that your adult brain may still be growing new neurons. Along the way: feathered dinosaurs, a collapsing food pyramid, and an astronaut who couldn't find the Great Wall. Missed Part 1? Pluto, Brontosaurus and your Neanderthal DNA are waiting there.
