Mary Posted February 23, 2008 Report Share Posted February 23, 2008 A new genetic analysis of people from around the world adds further confirmation to the African origin of humans. The study of genetic details from 938 individuals from 51 populations provides evidence of how people are related and different, researchers led by Richard M. Myers of Stanford University report in Friday's issue of the journal Science. The team looked at variations in 650,000 sections of each of the DNA samples, providing a view of the similarities and differences between people in greater detail than had been available previously. Scientists have long believed that modern humans first developed in Africa and spread from there to populate the rest of the world, a theory strongly supported by the new analysis, the researchers said. In addition, they noted that residents of the Middle East can trace their ancestry to both Africa and Europe, which they said is logical since the region formed a bridge for movement back and forth between the areas. Also, they noted, they found a close a relationship between the Yakut population of Siberia and native Americans, who are believed to have migrated from Siberia via a land bridge at a time of lower sea levels.

Mary Posted February 23, 2008 Author Report Share Posted February 23, 2008 I know you did Observer - but this is a newer version and is proving the theory you brought up dear. I think its quite interesting - with racism and classism run rampant - that we are all related after all! Quote Link to comment Share on other sites More sharing options...
observer Posted February 23, 2008 Report Share Posted February 23, 2008 Actually it strengthens the arguement behind less global mobilty; as it proves we are products of, and adapted to, our own enviroments: thus the adage "there are no Polar Bears at the Equator"!

tonymaillman Posted February 26, 2008 Report Share Posted February 26, 2008 Very true ....... all living things adapt over many years to their particular surroundings, same can be said of plants and foliage ....... some can survive in conditions that others couldn't .........

observer Posted February 26, 2008 Report Share Posted February 26, 2008 The estimated time period for a human to change their ethnic features by living at a different latitude is 20,000 years, that's without cross breeding. Quote Link to comment Share on other sites More sharing options...
