It contains only 16569 base pairs, encoding 37 genes, accounting for only a very small part of the human genome, about one hundred thousand of the whole genome. The most significant feature of mitochondrial DNA is maternal inheritance, because in the process of fertilization, sperm mitochondria are usually located in the tail, after fertilization is degraded or excluded, does not participate in the subsequent embryonic development. Therefore, it can be argued that our mitochondrial DNA only comes from the mother, is passed on from the mother to the child, and can only continue to pass down through the daughter.\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/tree_24.25.27/1761527379432_Mitochondrial_DNA-copy2.jpg\" alt=\"Mitochondrial_DNA\" width=\"70%\"/>\n\u003Cspan>\nImage source: \u003Ca href=\"https://en.wikipedia.org/wiki/Mitochondrial_DNA\" target=\"_blank\">wikipedia\u003C/a>\n\u003C/span>\n\u003Cp class=\"description\">Mitochondrial DNA is a circular DNA molecule present within the mitochondria. As an organelle, mitochondria are found in most eukaryotic cells and are the energy factories of cells. Mitochondria and mitochondrial DNA are passed from mother to offspring primarily through the egg cell.\n\u003C/p>\n\u003C/div>\n\nBecause the mitochondrial DNA sequence is shorter, it is easier for scientists to analyze. The way to find this maternal co-ancestor relies mainly on tracking the mutation differences in mitochondrial DNA. In 1987, Allan Wilson of the University of California, Berkeley, and his colleagues analyzed hundreds of mitochondrial DNA sequences from different populations around the world, similar to the way water waves spread back to the point where a stone falls: there are sequence differences in the mitochondrial DNA of different populations, just as there are differences in ripples at different locations in a pond.\n\nThrough this indicative law, scientists not only reconstructed the human maternal lineage tree, but also found that no matter where in the world these mitochondria came from, they can eventually be traced back to the same female ancestor living in Africa.\n\nThe discovery caused a stir at the time, with the media figuratively calling the female ancestor \"Mitochondrial Eve\" (Mitochondrial Eve). A more precise definition of this concept is: \"**Considering only the matrilineal lineage, the woman**who is closest to us in the most recent common ancestor of all humans today.\"\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/tree_24.25.27/1761529551544_mtdna-mrca-generations-evolution.png\" alt=\"线粒体夏娃示意图\" width=\"80%\"/>\n\u003Cspan>\nPhoto by \u003Ca href=\"https://mujeresconciencia.com/2015/11/23/rebecca-cann-al-rescate-de-la-eva-mitocondrial-en-el-tunel-del-tiempo/631px-mtdna-mrca-generations-evolution-svg/\" target=\"_blank\">mujeresconciencia.com\u003C/a>\n\u003C/span>\n\u003Cp class=\"description\">because each of us has only one type of mitochondrial DNA(mtDNA) that cannot be exchanged with other people and can only be passed on through the mother; if a woman does not have daughters, her mitochondrial DNA will be cut off. Therefore, some mtDNA may be extinct in each generation, as shown in the non-black maternal branch. But the continuation of human beings to this day also means that if you trace back up the mother's lineage, you will definitely reach a woman who carries mtDNA that is the most recent common ancestor of mtDNA (Most Recent Common Ancestor,MRCA) of all modern people today. The mitochondrial lineages of other women that existed at the same time in the era she lived in were later completely interrupted for various reasons. This woman is the famous \"Mitochondrial Eve\", the black female individual at the top of the picture.\u003C/p>\n\u003C/div>\n\n## The Age of Mitochondrial Eve\n\nAccording to a multidisciplinary analysis of evidence, Mitochondrial Eve came from Africa, but at what age did she live?\n\nAccording to the best current estimates, Mitochondrial Eve lived about 160000 years ago (there are many versions of this era, and Big History Online uses data given in David Reich's \"The Story of Human Origins\"). However, it should be noted that this era was deduced through genetics, mainly based on the assumption that the rhythm of gene mutations occurs at a certain rate and meets the \"molecular clock\" condition. However, this date is not accurate, mainly because there is still some controversy about the true mutation rate of human DNA.\n\nMitochondrial Eve and her age is not static, but a dynamic process, determined by all people today.**She is not everyone's\" recent common ancestor \"**, but can only be traced through the \"maternal\" this clue results. Because there are many other paths to confirm the \"recent common ancestor\", such as mother-father-father-mother, or mother-mother-father-father, etc., to name a few. Each independent genetic pathway corresponds to a different recent common ancestor. The most recent common ancestor of these different paths, which together link all mankind as a whole, most of them lived far later than Mitochondrial Eve (or Y-chromosome Adam).\n\nMoreover, the title of Mitochondrial Eve will continue to change hands: for example, if the last member of a remote tribe suddenly died, the title of \"Mitochondrial Eve\" would be suddenly pushed forward for many years.\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/tree_24.25.27/1761529657182_Mitochondrial_Eve2.jpg\" alt=\"线粒体夏娃变化示意图\" width=\"80%\"/>\n\u003Cspan>\nImage source: \u003Ca href=\"https://en.wikipedia.org/wiki/Mitochondrial_Eve\" target=\"_blank\">wikipedia\u003C/a>\n\u003C/span>\n\u003Cp class=\"description\">the title of Mitochondrial Eve is always changing, for example, assuming that the black lineage in the picture fails to continue, the title of Mitochondrial Eve (mtDNA MRCA) will shift to the next woman with at least two daughters. Obviously, \"having two daughters\" is one of the necessary conditions for mitochondrial Eve, because if there is only one daughter, the title will be worn on the head of the daughter.\u003C/p>\n\u003C/div>\n\n## The Meaning of Mitochondrial Eve\n\n**Mitochondrial Eve has nothing to do with the\" first woman \"in religion or mythology**. She is a woman inferred through genetic methods and has actually existed in history. Her existence reveals the common origin of all modern humans in the maternal line. But she was not the only woman at that time, let alone the \"first woman\" in human history, and there was no contemporaneous or spousal relationship with \"Y chromosome Adam\". The probability that the two were once husband and wife was almost zero.\n\nThe confirmation of mitochondrial Eve reveals two facts: first, modern human mitochondrial diversification occurred within 200000 years; second, modern human origins in Africa. This poses a strong challenge to the \"multi-regional independent origin hypothesis\", because according to this hypothesis, the ancestors of modern humans did not all come from the same late Homo sapiens group in Africa, but in Africa, Asia, Europe and other regions. Homo (such as Homo erectus) evolved independently.\n\n\u003Cdiv class=\"img-container-article\">\n\u003Cimg src=\"https://image.big-history.online/tree_24.25.27/1761529800714_Early_human_migrations2.jpg\" alt=\"追踪线粒体DNA\" width=\"80%\"/>\n\u003Cspan>\nImage source: \u003Ca href=\"https://en.wikipedia.org/wiki/Early_human_migrations\" target=\"_blank\">wikipedia\u003C/a>\n\u003C/span>\n\u003Cp class=\"description\">modern migration model constructed by tracking the differentiation of mitochondrial DNA, the color indicates the age from the present, and the unit is millennia.
