Every so often there is a very small harmless mutation which doesnt effect anything other than that scientists can read it; they can see the mutation. The origins of humanity can be traced back to Africa, with Homo sapiens found in Africa's Great Rift Valley about 200,000 years ago. Two hundred thousand years ago, perhaps it was home. This sounds like interesting science, but a film? Black American's genes reflect the hardships and realities - NBC News https://www.smithsonianmag.com/science-nature/no-mitochondrial-eve-not-first-female-species-180959593/. Can you explain this in laymans terms? The DNA held inside mitochondria can therefore reveal the maternal lineage to ancient 'Eve', who is believed to have lived in Africa between 99,000 and 148,000 years ago - almost the same time period during which the Y chromosome 'Adam' lived. ", There are sites in mtDNA (such as: 16129, 16223, 16311, 16362) that evolve more rapidly, have been noted to change within intragenerational timeframes , Last edited on 19 February 2023, at 17:13, human mitochondrial DNA (mtDNA) haplogroups, "Correcting for purifying selection: an improved human mitochondrial molecular clock", "Sequencing Y chromosomes resolves discrepancy in time to common ancestor of males versus females", "A revised timescale for human evolution based on ancient mitochondrial genomes", "New 'molecular clock' aids dating of human migration history", "An African American paternal lineage adds an extremely ancient root to the human Y chromosome phylogenetic tree", "The father of all men is 340,000 years old", "Low-pass DNA sequencing of 1200 Sardinians reconstructs European Y-chromosome phylogeny", "Rapid evolution of animal mitochondrial DNA", "Evolutionary tree for apes and humans based on cleavage maps of mitochondrial DNA", "Polymorphism in mitochondrial DNA of humans as revealed by restriction endonuclease analysis", "Length mutations in human mitochondrial DNA", "All about mitochondrial eve: an interview with Rebecca Cann. Well, because of the genetic tracing we know that everybody outside Africa carries a mitochondrial marker of one woman who must have been in a group of people who left Africa about 80,000 years ago. The Seven Daughters of Eve 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. The word "woman" means one female. Neanderthal genes found for first time in African populations This is called the "Eve Gene" and is ONLY found in black women." They even claim the black madonna as Eve. [] estimates the coalescence time of the mtDNA tree overall at ~160,000 kya [] We present a revised chronology using the complete mtDNA genome rate and an ML approach for the mtDNA tree in Figure 6, with full details of the age estimates and associated 95% confidence regions in Table S5. And then there was a native American who was a full-blooded Cree. "Scientifically, the black woman is the only organism that possesses the Mitochondrial DNA that has all the variations possible for every different kind of human being on this earth. 11 votes, 12 comments.
