judging a book by its cover: maybe african origins.

dr. livingstone, i presume.
the most interesting thing is the diary of dr. david livingstone. he relates his explorations of africa. the first foreigner from the western civilization to the interior of africa; he found that the slavers who originated the african slave trade were arabian muslims. they were reported to commit horrendous acts against the africans, murdering many, and selling the rest in slavery to the americas, cuba, and the east indies, and brittan.

Timeline of human origins revised: New synthesis of research links changing environment with Homo's evolutionary adaptability

Summary:
Many traits unique to humans were long thought to have originated in the genus Homo between 2.4 and 1.8 million years ago in Africa. Although scientists have recognized these characteristics for decades, they are reconsidering the true evolutionary factors that drove them::::::::::::::::

The in-Laws Through History
Mixed genes: Interactive world map of human genetic history reveals likely genetic impacts of historical events
Date:
February 13, 2014
-----'science'--------
Admixture, the result of previously distant populations meeting and breeding, leaves a genetic signal within the descendants' genomes. However, over time the signal decays and can be hard to trace. Hellenthal et al. (p. 747) describe a method, using a technique called chromosome painting, to follow the genetic traces of admixture back to the nearest extant population. The approach revealed details of worldwide human admixture history over the past 4000 years.

A Genetic Atlas of Human Admixture History
Modern genetic data combined with appropriate statistical methods have the potential to contribute substantially to our understanding of human history. We have developed an approach that exploits the genomic structure of admixed populations to date and characterize historical mixture events at fine scales. We used this to produce an atlas of worldwide human admixture history, constructed by using genetic data alone and encompassing over 100 events occurring over the past 4000 years. We identified events whose dates and participants suggest they describe genetic impacts of the Mongol empire, Arab slave trade, Bantu expansion, first millennium CE migrations in Eastern Europe, and European colonialism, as well as unrecorded events, revealing admixture to be an almost universal force shaping human populations.
