From Karen Rosenberg, University of Delaware, Newark
Your article on human origins dealt with the two leading models, the
“multiregional model” and “out of Africa”
(14 April, p 26). I write to correct
an impression created by the diagram accompanying the article. It suggests that
separate and isolated populations of Homo erectus evolved independently
into modern Homo sapiens, which is a biological impossibility. Such a
model in no way represents the multiregional model, which emphasises gene flow
between regions.
