The paper Hominin occupation of the Chinese Loess Plateau since about 2.1 million years ago by Zhaoyu Zhu et al, published today in Nature, is very interesting as it pushes back the date of an early hominin migration into Asia well beyond the Dmanisi hominins found in Georgia:
The abstract states:
"Considerable attention has been paid to dating the earliest appearance of hominins outside Africa. The earliest skeletal and artefactual evidence for the genus Homo in Asia currently comes from Dmanisi, Georgia, and is dated to approximately 1.77–1.85 million years ago (Ma). Two incisors that may belong to Homo erectus come from Yuanmou, south China, and are dated to 1.7 Ma; the next-oldest evidence is an H. erectus cranium from Lantian (Gongwangling)—which has recently been dated to 1.63 Ma—and the earliest hominin fossils from the Sangiran dome in Java, which are dated to about 1.5–1.6 Ma. Artefacts from Majuangou III5 and Shangshazui6 in the Nihewan basin, north China, have also been dated to 1.6–1.7 Ma. Here we report an Early Pleistocene and largely continuous artefact sequence from Shangchen, which is a newly discovered Palaeolithic locality of the southern Chinese Loess Plateau, near Gongwangling in Lantian county. The site contains 17 artefact layers that extend from palaeosol S15—dated to approximately 1.26 Ma—to loess L28, which we date to about 2.12 Ma. This discovery implies that hominins left Africa earlier than indicated by the evidence from Dmanisi."
And this is in China, surely the hominins who made those tools reached western Eurasia far earlier than the 2.12 My age assigned to those tools. Which may imply that they were not Homo erectus, maybe Homo habilis or even an australopithecine species! (maybe the ancestors of the primitive Flores island "Hobbit").
Maybe there are older tools at the site. The ones found are cobbles similar to those found in Africa with a similar age.
