The "Eve" in question was actually the most recent common ancestor through matrilineal descent of all humans living today. That is, all people alive today can trace some of their genetic heritage through their mothers back to this one woman.
In human genetics, the Mitochondrial Eve (also mt-Eve, mt-MRCA) is the matrilineal most recent common ancestor (MRCA) of all living humans.
Well, this makes it possible for us to trace these chromosomes back into the distant past. In fact, we can trace the mtDNA back to a woman from about 150,000 or 200,000 years ago that everyone on the planet is related to. And the Y chromosome to a man we're all related to from 60,000 or so years ago.
All humans share a common direct maternal ancestor known as Mitochondrial Eve. Mitochondrial DNA found in our cells is the genetic signature that passes from mother to child. Mitochondrial Eve was a woman who lived 200,000 years ago who had enough daughters in a continuous chain that her Mitochondrial DNA survived.
All humans, regardless of race (which is a social construct) can trace their ancestry to a Black woman from southern Africa who walked this earth over 100,000 years ago. Today, scientist call her Mitochondrial Eve and her DNA can be found in Black women today.
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa.
The First Humans
One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
Subsequently, Eve is created from one of Adam's ribs to be his companion. They are innocent and unembarrassed about their nakedness.
We are, in fact, remarkably similar. The DNA of all human beings living today is 99.9% alike. We all have roots extending back 300,000 years to the emergence of the first modern humans in Africa, and back more than 6 million years to the evolution of the earliest human species in Africa.
Chimpanzees are the closest living relatives of humans. The divergence between human and chimpanzee ancestors dates to approximately 6,5–7,5 million years ago.
Finding mitochondrial ancestors
Even though everyone on Earth living today has inherited his or her mtDNA from one person who lived long ago, our mtDNA is not exactly alike. Random mutations have altered the genetic code over the millennia. But these mutations are organized, in a way.
Until recently, scientists could not look at someone's DNA and figure out how old they were. Now you can, but it isn't always super accurate. Scientists noticed in 2013 that as people age, they build up the same set of specific DNA changes at the same times.
The molecule of life has a lifespan of its own. A study of DNA extracted from the leg bones of extinct moa birds in New Zealand found that the half-life of DNA is 521 years. So every 1,000 years, 75 per cent of the genetic information is lost. After 6.8 million years, every single base pair is gone.
In a technical feat, researchers sequenced the oldest human DNA yet, retrieving an almost complete mitochondrial genome from a 300,000- to 400,000-year-old sliver of human bone found in Spain's Atapuerca Mountains. To their surprise, this proto-Neandertal yielded ancestral Denisovan DNA.
The even-skipped (eve) pair-rule gene plays a key role in the establishment of the anterior-posterior segmental pattern of the Drosophila embryo. The continuously changing pattern of eve expression can be resolved into two phases.
The oldest known evidence for anatomically modern humans are fossils found at Jebel Irhoud, Morocco, which date back some 360,000 years ago.
The God gene hypothesis proposes that human spirituality is influenced by heredity and that a specific gene, called vesicular monoamine transporter 2 (VMAT2), predisposes humans towards spiritual or mystic experiences.
Several years ago, the Almanac carried an article on the length of one's family tree. In brief, this is what it said: According to the leading geneticists, no human being of any race can be less closely related to any other human than approximately fiftieth cousin, and most of us are a lot closer.
If you're ever feeling lonely, remember this statistic: You're related to every human being on the planet. And you don't need to go back that far to find where your lineages intersect. Every person alive today shares a common ancestor who lived a mere 3000 years ago.
The Adamic language, according to Jewish tradition (as recorded in the midrashim) and some Christians, is the language spoken by Adam (and possibly Eve) in the Garden of Eden.
Their own particular ethnicity is not even mentioned, for the Bible seems to stress that they are the mother and father of all peoples of all ethnicities. Adam and Eve are presented as non-ethnic and non-national because they represent all people of all ethnicities.
The location of Eden is described in the Book of Genesis as the source of four tributaries. Various suggestions have been made for its location: at the head of the Persian Gulf, in southern Mesopotamia where the Tigris and Euphrates rivers run into the sea; and in Armenia.
The oldest human remains in Australia were found at Lake Mungo in south-west New South Wales, part of the Willandra Lakes system. This site has been occupied by Aboriginal people from at least 47,000 years ago to the present.
Co-lead researcher Shimona Kealy said these people probably travelled through Indonesia's northern islands, into New Guinea and then Australia, which were part of a single continent between 50,000 and 70,000 years ago, when sea levels were 25-50 metres below the current level.
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
