ca" hypothesis suggests a single origin in Africa followed by several dispersal’s. The "multiregional" hypothesis, in contrast, proposes parallel origins of Homo in different regions ofEurope, Africa, and Asia. But the Chinese believe in the "Asian Hypothesis", or Asian origins of the genus.Both sides agree that plate tectonic movements caused climatic changes from East Africa to East Asia. Theweather tended to be more "[…] seasonal and arid", instigating arboreal apes to move onto the savannahand evolve into upright hominins (Ciochon 15).A large fissure in Anhui Province has yielded 3,000 bones of animals of 60 species. Some animalsincluded a tapir and a mastodon. Another one of the species included is the monkey Procynocephalus,determining that that area was open to the environment about 2.5 million years ago. Also found were 50stones and bones cut to be used as choppers, similar to those found in Africa. Most East Asian toolsfound tend to be flakes with one side removed, called choppers. The only problem is that sometimes thesetools can be confused with rocks formed asymmetrically from wear and tear, including rain, snow ,and yearsof movement and erosion. These tools were used for digging, cutting wood, capturing animals, cleaningand cutting meat, and scraping hides. Early hominins could have gone into the fissure and butchered theanimals for food after they had fallen into the hole. Evidence for this is provided by the findings of the tapirseemingly to be laid out for butchering and the mastodon skeletons piled on one of the side walls. Procynocephalus skeletons as well as similar monkeys and H. erectus fossils have been foundtogether both in East Africa and Asia. In Longgupo, a mandible fragment found had two worn out molarsfrom the Procynocephalus monkey. Western scientists believe these “[...] teeth share features with earliestHomo in East Africa-leading us to suggest a direct link, a “dispers...
