People on Earth share a common source?

According to Professor Joseph Chang of Yale University (USA), everyone living on Earth today has common ancestors from people who lived about 3,500 years ago, which can start in Asia.

Mr. Chang has developed a detailed mathematical model of human migration process by performing various computer simulations on history, tracing and cross-breeding ability of all children. The ancient people combined elements such as geographical obstacles to the migration process and world events to estimate the lifespan of the most recent common ancestor of humankind.

Professor Chang concluded that everyone could be cousins ​​of the 100th or more generations. Joseph Chang stated: ' The most recent common ancestor time to live in 1415 BC in a place in East Asia and this starting point may have allowed later generations to quickly migrate to Europe and Europe. America and the Pacific Islands.

These were the ancient humans who had known domesticated horses on the prairies of Ukraine, used to build the ancient pyramids of Khufu in Egypt or used to hunt loris - slow moving mammals - North and South America '.
