In other words, she is defined as the most recent woman from whom all living humans descend in an unbroken line purely ...
Rebecca L. Cann (born 1951) is a geneticist who made a scientific breakthrough on mitochondrial DNA variation and evolution in humans, popularly called Mitochondrial Eve.Her discovery that all living humans are genetically descended from a single African mother who lived <200,000 years ago became the foundation of the Out of Africa theory, the most widely accepted explanation of the origin of ...
The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

The Seven Daughters of Eve [1] is a 2001 semi-fictional book by Bryan Sykes that presents the science of human origin in Africa and their dispersion to a general audience. [2] Sykes explains the principles of genetics and human evolution , the particularities of mitochondrial DNA, and analyses of ancient DNA to genetically link modern humans to ...

Haplogroup A is the NRY (non-recombining Y) macrohaplogroup from which all modern paternal haplogroups descend.It is sparsely distributed in Africa, being concentrated among Khoisan populations in the southwest and Nilotic populations toward the northeast in the Nile Valley.
A heroin addict entering a rehab facility presents as severe a case as a would-be suicide entering a psych ward. The addiction involves genetic predisposition, corrupted brain chemistry, entrenched environmental factors and any number of potential mental-health disorders — it requires urgent medical intervention.
Meek may have not debunked the “Pizzagate” conspiracy theory himself, but plenty of reputable journalists have: Both the New York Times and Snopes reported in November 2016 that the conspiracy ...
