Is it possible social / cultural organization by choice of each individual still remains the key factor in intelligence. Ashkenazi's in the most part seem to have been prostelized as a orgaized way of life...jewish, yet not wholly original by blood lines. After the Fall of the Temple in 70 AD, a new organization became comitted to prostelize. Seemingly there are closer genetic blood lines, within the Sephardic Jew communities.Not to mention not long ago wasn't it revealed, there are even closer gentic blood lines as the original hebrews in Africa.The Ashkenazi's held onto a tradition of organized communities, and only married within the community. Yes the Chinese, and many Aboriginal peoples, have continued to do so. The Kogi's in Columbia, have literally close there door to the rest of the world. The Elder Brother's, believe we are less evolved spiritually, and have passed down the stories to every generation for 1000 years. They were happy to meet some younger brother's, who seemed to not be like the stories of old, as they finally opened their doors to a select few. Read about the horrifying ways they were killed for their gold artifacts, including they were accused of homo sexual acts, because they lived separate from their wives.( just an excuse to kill)

It was short lived...they have been subjected to greed, deciet and murder, and prefer to keep to themselves. im not as articulate as the rest of you speaking to this subject, I often wonder, if the human race would be better equiped to fight disease, and live well spiritually.. if we married outside our community, and organizations....not less, so as to increase our power to Love one another more???. All the intelligence in the world, has continued to fall short......
