Explanation:
Jim Crow laws were state and local laws that enforced racial segregation in the Southern United States.[1] These laws were enacted in the late 19th and early 20th centuries by white Southern Democrat-dominated state legislatures to disenfranchise and remove political and economic gains made by black people during the Reconstruction period.[2] The Jim Crow laws were enforced until 1965.[3]
In practice, Jim Crow laws mandated racial segregation in all public facilities in the states of the former Confederate States of America and in some others, beginning in the 1870s. Jim Crow laws were upheld in 1896 in the case of Plessy vs. Ferguson, in which the U.S. Supreme Court laid out its "separate but equal" legal doctrine for facilities for African Americans. Moreover, public education had essentially been segregated since its establishment in most of the South after the Civil War in 1861–65.
The legal principle of "separate but equal" racial segregation was extended to public facilities and transportation, including the coaches of interstate trains and buses. Facilities for African Americans were consistently inferior and underfunded compared to facilities for white Americans; sometimes, there were no facilities for the black community.[4][5] As a body of law, Jim Crow institutionalized economic, educational, and social disadvantages for African Americans living in the South.

Explanation:
In human genetics, the Mitochondrial Eve (also mt-Eve, mt-MRCA) is the matrilineal most recent common ancestor (MRCA) of all living humans, i.e., the most recent woman from whom all living humans descend in an unbroken line purely through their mothers and through the mothers of those mothers, back until all lines converge on one woman.
In terms of mitochondrial haplogroups, the mt-MRCA is situated at the divergence of macro-haplogroup L into L0 and L1–6. As of 2013, estimates on the age of this split ranged at around 150,000 years ago,[note 3] consistent with a date later than the speciation of Homo sapiens but earlier than the recent out-of-Africa dispersal.[4][1][5]
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. 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[6][7][8] (with an estimated age of between 120,000 and 156,000 years ago, roughly consistent with the estimate for mt-MRCA.).[2][9]
The name "Mitochondrial Eve" alludes to biblical Eve, which has 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 mitochondrial DNA (mtDNA) 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".[note 4]
