Mitochondrial Eve is the most recent common matrilineal ancestor for all modern humans. Whenever one of the two most ancient branch lines dies out (by producing only non-matrilinear descendants at that time), the MRCA will move to a more recent female ancestor, always the most recent mother to have more than one daughter with living maternal ...
All modern humans share the same origin from this single ancestral population. Modern polygenists do not accept either theological or scientific monogenism. They believe that the variation among human racial types cannot be accounted for by monogenism or by evolutionary processes occurring since the proposed recent African origin of modern humans .
In 1970, Black women held about 3% [17] of leadership roles. By 1990, this figure had risen to 19%. In 1890, 7% of black women in Protestant churches were given full clergy rights, but 100 years later 50% had these same rights. Often, women do not receive the higher level or more visible roles.

Monogenism or sometimes monogenesis is the theory of human origins which posits a common descent for all humans. The negation of monogenism is polygenism.This issue was hotly debated in the Western world in the nineteenth century, as the assumptions of scientific racism came under scrutiny both from religious groups and in the light of developments in the life sciences and human science.

The one-drop rule was a legal principle of racial classification that was prominent in the 20th-century United States. It asserted that any person with even one ancestor of African ancestry ("one drop" of "black blood") [1] [2] is considered black (Negro or colored in historical terms).
All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA. A new study suggests that this organism likely lived on Earth only 400 million years after its formation.
