On April 6, 1652 the first white people (Dutch) arrived in South Africa to establish a settlement at the Cape. Their purpose, initially, was not to colonize the area, but to s â¦ upply fresh food for the men on the Dutch ships sailing on the long route between Europe and India.
These findings might give some support to the claim that modern humans from Africa arrived at southern China about 100,000 years BP (Zhiren Cave, Zhirendong, Chongzuo City: 100,000 years BP; and the Liujiang hominid (Liujiang County): controversially dated at 139,000â111,000 years BP).he expansion of modern human population is thought to have begun 45,000 years ago, and may have taken 15,000-20,000 years for Europe to be colonized. During this time the Neanderthals were slowly being displaced.
