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 Skyes), 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. In his latest project, Sykes is doing DNA testing of suspected Yeti and Bigfoot hair samples in tandem with the University of Lausanne in Switzerland. So far, some of the samples have turned out to be from bears. If the results indicate an unknown species, he said could compare DNA sequences and place the species somewhere on the evolutionary tree, such as between chimps and humans. Recent evidence has shown that in addition to Neanderthals, there were other human-type species living concurrently with homo sapiens, and Sykes posited that Bigfoot and Yeti might be "small relic populations of these other human species."
