A maternal ancestor to all living humans called mitochondrial Eve likely lived about 200,000 years ago, at roughly the same time anatomically modern humans are believed to have emerged, a new review study confirms.
Mitochondrial Eve is a female biological ancestor of humans, aptly named the mother of all humans. It might seem very unusual or even impossible, but the DNA inside the mitochondria explains everything.
'Mitochondrial Eve': Mother of all humans lived 200,000 years ago. Summary: The most robust statistical examination to date of our species' genetic links to "mitochondrial Eve" -- the maternal ancestor of all living humans -- confirms that she lived about 200,000 years ago.
This woman, known as “mitochondrial Eve”, lived between 100,000 and 200,000 years ago in southern Africa.
Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind".
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.
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means 'upright man' in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.
From about 1.2 million years ago to less than 100,000 years ago, archaic humans, including archaic Homo sapiens, were dark-skinned.
Basic math tells us that all humans share ancestors, but it's amazing how recently those shared ancestors lived. Thanks to genetic data in the 21st century, scientists are discovering that we really are all descended from one mother.
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. Most scientists currently recognize some 15 to 20 different species of early humans.
Overview. Homo sapiens, the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago.
Ardipithicines. Ardipithecus is the earliest known genus of the human lineage and the likely ancestor of Australopithecus, a group closely related to and often considered ancestral to modern human beings. Ardipithecus lived between 5.8 million and 4.4 million years ago.
Our species likely arose in many places around Africa, not just around the Kalahari Desert, critics say. A new genetic study suggests all modern humans trace our ancestry to a single spot in southern Africa 200,000 years ago.
It is important to note that mitochondria have their own DNA that carry this particular 'Eve'/L0 genome. This more commonly termed as mitochondrial DNA (mtDNA). It is thus nicknamed the 'Eve Gene' as it is an inherited gene, paying reference to the story of creation in Genesis, the first chapter of the Bible.
Widely believed to be the “cradle of humankind,” Africa is the only continent with fossil evidence of human beings (Homo sapiens) and their ancestors through each key stage of their evolution.
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.
Blue-eyed? Thank a genetic switch that turns off your body's ability to make brown pigment in your peepers. Researchers have finally located the mutation that causes blue eyes, and the findings suggest that all blue-eyed humans share a single common ancestor born 6000 to 10,000 years ago.
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.

A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
Genetic studies have demonstrated that humans are still evolving. To investigate which genes are undergoing natural selection, researchers looked into the data produced by the International HapMap Project and the 1000 Genomes Project.
Humans lost their body hair, they say, to free themselves of external parasites that infest fur -- blood-sucking lice, fleas and ticks and the diseases they spread. Once hairlessness had evolved through natural selection, Dr. Pagel and Dr.
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.
Evidence still suggests that all modern humans are descended from an African population of Homo sapiens that spread out of Africa about 60,000 years ago but also shows that they interbred quite extensively with local archaic populations as they did so (Neanderthal and Denisovan genes are found in all living non-Africa ...
They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago. A comparable analysis of the same men's mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago1.
