Between 1927 and 1937, paleontologists excavated fossils from about 40 members of the species that today we call Homo erectus from a site in China known as Dragon Bone Hill. And then World War II broke out and the fossils were lost. In this episode, we trace their path as far as the historical record will take us and explore what might’ve happened to them after their last sighting in early December, 1941.
