Alan Templeton

In 2002, Templeton published a genetic analysis showing that some gene variants that are present in modern populations existed already in Asia hundreds of thousands of years ago. This meant that even if our male line (Y chromosome) and our female line (mitochondrial DNA) came out of Africa in the last 100,000 years or so, we have inherited other genes from populations that were already outside of Africa. Since this study other studies have been done using much more data (see Phylogeography). According to Templeton's research, perceived differences in races are more related to cultural perceptions and biases than any underlying genetic reality. For example, Templeton's statistical analysis of the human genome shows that much greater genetic diversity exists between populations of chimpanzees than humans from different parts of the world. ==References==
