Johan Gunnar Andersson
Paleontologists who believed humans originated in Asia also include Johan Gunnar Andersson, Otto Zdansky and Walter W. Granger. All three of these scientists were known for visiting China and for their work and discoveries by excavating the sites at Zhoukoudian that yielded remains of so-called Peking man ("Homo erectus pekinensis"). Further funding for the excavations was carried out by Davidson Black a key proponent of the out of Asia theory. Because of the finds in Zhoukoudian, such as Peking Man, the focus of paleoanthropological research moved entirely to Asia, up until 1930.
