Eve dating white men

Using molecular clock methods in the late 1970s, Allan Wilson, Mark Stoneking, Rebecca L. Brown found that mutation in human mt DNA was unexpectedly fast.It exhibited 0.02 substitution per base (1%) in a million years, which is 5–10 times faster than in nuclear DNA.As of 2013, estimates for the age Y-MRCA are subject to substantial uncertainty, with a wide range of times from 180,000 to 580,000 years ago).The name "Mitochondrial Eve" alludes to biblical Eve.As of 2018 The male analog to the "Mitochondrial Eve" is the "Y-chromosomal Adam" (or Y-MRCA), the individual from whom all living humans are patrilineally descended.As the identity of both matrilineal and patrilineal MRCAs is dependent on genealogical history (pedigree collapse), they need not have lived at the same time.Through random drift or selection the female-lineage will trace back to a single female, such as Mitochondrial Eve.

One common misconception surrounding mitochondrial Eve is that since all women alive today descended in a direct unbroken female line from her, she must have been the only woman alive at the time.Major branches are said to define a haplogroup (e.g.CRS belongs to haplogroup H), and large branches containing several haplogroups are called "macro-haplogroups".This led to repeated misrepresentations or misconceptions in journalistic accounts on the topic.Popular science presentations of the topic usually point out such possible misconceptions by emphasizing the fact that the position of mt-MRCA is neither fixed in time (as the position of mt-MRCA moves forward in time as mt DNA lineages become extinct), nor does it refer to a "first woman", nor the only living female of her time, nor the first member of a "new species".
