Bryan Sykes, Professor of Human Genetics at the University of Oxford, is one of the world's leading geneticists. After undertaking medical research into the causes of inherited bone disease, he discovered DNA could survive in ancient bones, and he was the first to report on the recovery of ancient DNA from archaeological bones in the journal, Nature, in 1989. Since then, Professor Sykes has been called in as the leading international authority to examine several high-profile cases, such as the Ice Man, Cheddar Man, and the many individuals claiming to be members of the Russian royal family. Prof. Sykes and his research team have, over the last decade, compiled the most complete DNA family tree of our species yet available. They are the founders of Oxford Ancestors Ltd., the world's leading provider of DNA-based services for use in personal ancestry research. (http://www.oxfordancestors.com/) (Show date: 07-9-12) Professor of Human Genetics at the University of Oxford since 1997, Bryan Sykes, discussed some of his fascinating DNA research findings, including his study of American genetics. The United States' population contains a convergence of DNA from a number of continents, with interesting crossovers such as some African Americans having European genes. According to earlier research (not done by Sykes), Native Americans actually originated from Siberia, China, and even Europe, but the DNA blood testing that yielded these results was done without their consent, and thus raised controversy and ire, he detailed. Interestingly, some people from Britain have been found to have Native American genes, he added. Sykes described his work on the "Seven Daughters of Eve." Astonishingly, almost everyone in Europe has mitochondrial (maternal) DNA they inherited from one of seven actual women who lived between 10,000 and 45,000 years ago. Additionally, there are "36 maternal ancestors spread throughout the world," he noted. It's suspected that Genghis Khan also established a legacy, with his particular Y chromosome shared among some 15 million males in Asia. The Y (male) chromosome in general has been subject to more degeneration and mutation than the X (female) chromosome, and if this continues males might eventually become extinct, he warned.
