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 ...
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.
Dark skin. All modern humans share a common ancestor who lived around 200,000 years ago in Africa. Comparisons between known skin pigmentation genes in chimpanzees and modern Africans show that dark skin evolved along with the loss of body hair about 1.2 million years ago and that this common ancestor had dark skin.
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.
300,000 Years Ago: Fossils Found of Oldest Homo sapiens.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
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.

The likely "first human", she says, was Homo erectus. These short, stocky humans were a real stayer in human evolutionary history. Estimates vary, but they're thought to have lived from around 2 million to 100,000 years ago, and were the first humans to walk out of Africa and push into Europe and Asia.
Homo erectus became the first direct human ancestor to leave Africa, and the first to display evidence of using fire. Homo habilis was likely driven to extinction more than a million years ago, as was the last Australopithecus.
The evolution of dark skin is believed to have begun around 1.2 million years ago, in light-skinned early hominid species after they moved from the equatorial rainforest to the sunny savannas.
Around 90 million years ago, our primitive mammalian ancestors were nocturnal and had UV-sensitive and red-sensitive color, giving them a bi-chromatic view of the world.
It's over one billion years old, and colored bright pink. Researchers discovered the color in cyanobacteria fossils preserved in rocks in the Sahara Desert. When scientists extracted pigment from the bacteria, they found dark red and deep purple spots in concentrated form. Distilled, it turned bright pink.
All living people share exactly the same set of ancestors before the Identical Ancestors Point, all the way to the very first single-celled organism. However, people will vary widely in how much ancestry and genes they inherit from each ancestor, which will cause them to have very different genotypes and phenotypes.
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.
According to the Bible (Genesis 2:7), this is how humanity began: "The Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul." God then called the man Adam, and later created Eve from Adam's rib.
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.
These stories were widely believed in Europe until early modern times. Regarding the real existence of the progenitors – as of other narratives contained in Genesis – the Catholic Church teaches that Adam and Eve were historical humans, personally responsible for the original sin.
Common Questions about Mitochondrial Eve
Mitochondrial Eve is the female ancestor of all human beings. The reason is that the mitochondrial DNA passes on only though mothers to children, and the father has no role in it.
The real Garden Of Eden has been traced to the African nation of Botswana, according to a major study of DNA. Scientists believe our ancestral homeland is south of the Zambezi River in the country's north.
This may even be a region that you had no idea about, such as the Cameroon region. With each generation, your DNA divides. So, for a 1% DNA result, you would be looking at around seven generations.
The islands were settled by different seafaring Melanesian cultures such as the Torres Strait Islanders over 2500 years ago, and cultural interactions continued via this route with the Aboriginal people of northeast Australia.
It is generally held that Australian Aboriginal peoples originally came from Asia via insular Southeast Asia (now Malaysia, Singapore, Brunei, East Timor, Indonesia, and the Philippines) and have been in Australia for at least 45,000–50,000 years.
Australia is made up of many different and distinct Aboriginal and Torres Strait Islander groups, each with their own culture, language, beliefs and practices. Aboriginal and Torres Strait Islander peoples are the first peoples of Australia, meaning they were here for thousands of years prior to colonisation.
