A 1.1 differential is a 15 to 18 point difference in IQ" Hmmmm ... that's an interesting statistic. One wonders how that came about, or from whence it originated. And that origin is especially intriguing when one considers the ongoing work that has been carried out under the Genographic Project for well over a decade by Dr. Spencer Wells, a National Geographic Explorer-in-Residence. The Genographic Project is a multi-year research initiative led by National Geographic Explorer-in-Residence Dr. Spencer Wells. Dr. Wells and a team of renowned international scientists are using cutting-edge genetic and computational technologies to analyze historical patterns in DNA from participants around the world to better understand our human genetic roots. The three components of the project are: •To gather and analyze research data in collaboration with indigenous and traditional peoples around the world •To invite the general public to join this real-time scientific project and to learn about their own deep ancestry by purchasing a Genographic Project Participation and DNA Ancestry Kit. •To use a portion of the proceeds from Genographic kit sales to further research and the Genographic Legacy Fund, which in turn supports community-led indigenous conservation and revitalization projects. Here are two links that one may find of interest ....genographic.nationalgeographic.com voices.nationalgeographic.com For ten years, Genographic Project scientists have explored and explained how patterns in our DNA show evidence of migration and expansion routes of our ancient ancestors across the globe. DNA has shown that genetically modern humans arose in Africa some 150,000 years ago, and around 60,000 years ago left Africa and went east into Asia, north into Europe, and south into Australia. Genographic Project scientists Drs. Ramasamy Pitchappan and GaneshPrasad ArunKumar from Tamil Nadu, India, analyzed the Y-chromosome (paternally-inherited) DNA from more than 10,000 men from southern Asia. Apparently there is a Y-Chromosome factor within males that can "mutate" over time. And these scientists have found that they can trace ancestry, and thereby movement of homo sapiens, based on younger and younger mutations of that original male chromosome. As a result of all those thousands and thousands of male DNA samples that they have taken or obtained, it has apparently become apparent that the earliest origin and movement of homo sapiens took place from Central Africa .... as in the following basic "route map" .... So, bearing in mind, that much of the ancestry of North America came about with the migrations from various parts of Europe, etc.., it seems that the Caucasian origins of North America all began, as it did with numerous other European and Eastern Asian nations, with that original negroid(?) migration from Africa. In fact there exists a tribe, today, in central Africa where the males still show the earliest "mutation" of that male chromosome. So if, many, many generations ago, there was apparently no genetic difference that could have existed within those earliest ancestors that "migrated" out of Central Africa, one has to wonder what, over time, could have caused that "1.1 differential is a 15 to 18 point difference in IQ" that you referred to ??
