The theory of development is backed up by dodos of the ‘Peking man’ found in China during the early 20th century. The current human species is believed to be the descendent of the Homo erectus. our predecessor species with a smaller encephalon and unsloped stature ; the Peking adult male is a races of this group and the corresponding dodo remains were estimated to be about 550. 000 old ages old.

However. recent Chinese dodo findings conducted by Nanjing Normal University in 2008 suggest the age of a Peking adult male skull to be at least 750. 000 old ages old. The Homo erectus species is believed to hold migrated from Africa about 2 Million old ages ago to Asia. The new estimated age of the Peking adult male fossils puts frontward the possibility of two different races holding settled in different parts of Asia during the same timeline. The Homo erectus species had inhabited China and other parts of Southeast Asia for over half a million old ages.

Harmonizing to University of Iowa’s Russell Ciochon. the Peking adult male is likely to hold coexisted with other Homo erectus races ; while one group of Homo erectus is assumed to hold settled down in semitropical countries of Zhoukoudian in China. the unfamiliar conditions could hold driven the other group Southeast which could hold evolved into what we today refer to as Peking adult male ( Handwerk 2009 ) . Ciochon uses the phrase “fork in the road” as an analogy to explicate this state of affairs ( Handwerk 2009 ) . This subspecies is assumed to hold possessed the ability to do tools out of rock and walk vertical.

Besides. its encephalon size being about 75 % the size of a Homo erectus makes it’s the closest descendent to human existences. The other group of Homo erectus settled in Zhoukoudian is believed to hold enjoyed a good supply of nutrient and familiar environment. giving rise to the races Homo erectus pekinensis. The earlier timeline would besides intend that this subspecies lived in a more pleasant clime in the grasslands. Furthermore. fossil grounds of carnal castanetss indicates that this group of Homo erectus settled in China consumed meat.

This ask foring proposition of nutrient and pleasant conditions could hold given raise to the early Homosexual sapiens to migrate from Africa to Asia. Homosexual sapiens are rather different from Homo erectus since they are marked by a more “rounded skull. divided forehead ridge. and chin” ( Platt 2008 ) . One school of idea spearheaded by Hou Ya-mei of Institute of Vertebrate Paleontology and Paleoanthropology points out the possibility of modern Homo sapiens coexisting. hybridization or even contending with Homo erectus. thereby detecting the theory of ‘survival of the fittest’ in action ( Platt 2008 ) .

The present human race is believed to hold originated out of Africa 60. 000 old ages ago. The differences in Homo erectus dodo forms in Asia and other parts of the universe had given rise to disagreement. which can be explained by a “secondary migration from Africa” ( University Of Cambridge ) . Even though this theory makes sense to an extent. Susan Anton of New York University is pessimistic about the back uping informations given to endorse up claims of two separate colonies of Homo erectus.

She merely mentions the possibility of any figure of migrations can be claimed. but those claims will go on to be void without strong back uping grounds. She furthers provinces that grounds such as the paths taken by the Homo erectus groups or a cardinal cohesive point of beginning in Africa would be needed to link the “Out of Africa” theory and these claimed migrations. However. Anton concludes by acknowledging that this theory and the alteration in the timeline would assist explicate why the Homo erectus had persisted longer in Continental Asia. Reference Handwerk.
