Early H. erectus had smaller, more primitive teeth, a smaller overall size and thinner, less robust skulls compared to later specimens. The species also had a large face compared to modern humans. Like Neanderthals, their skull was long and low, rather than rounded like our own, and their lower jaw lacked a chin.
From about 1.2 million years ago to less than 100,000 years ago, archaic humans, including archaic Homo sapiens, were dark-skinned.
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.
Another skeleton from the same cave gave us Neanderthal DNA from 120,000 years ago. But all of this DNA has something in common: Almost all of it comes from Europe and Asia. The oldest DNA from sub-Saharan Africa—the place where the whole human story began—dates back to less than 10,000 years ago.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
Researchers agree that our early australopithecine ancestors in Africa probably had light skin beneath hairy pelts.
A new genetic study suggests all modern humans trace our ancestry to a single spot in southern Africa 200,000 years ago.
A study on the genomes of Anatolian Neolithic farmers in West Eurasia (6500–300 BC), who are probably the source population of the first European farmers, suggests that the light skin color has been evolved since at least 6500–4000 years ago [98].
The genetic evidence suggests that black skin became the norm in Africa some 1.2 million years ago, around the time that early humans were colonizing the savanna and had lost most of their body hair.
As populations migrated away from the tropics into areas of low UV radiation, they developed light skin pigmentation as an evolutionary selection acting against vitamin D depletion.
From his research, he's found that people from Senegal and the islands of Micronesia have some of the darkest skin tones in the world. That's typical in countries close the equator, where the dark pigment melanin protects against UV damage from the sun's rays.
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.
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
The last “sympatric” humans we know of were Neanderthals, who became extinct only about 30,000 years ago. Since stable separation of parts of the species is the key factor for the formation of new species, we can say that a new split of our species is impossible under current circumstances.
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.
Many scientists have believed that lighter skin gradually arose in Europeans starting around 40,000 years ago, soon after people left tropical Africa for Europe's higher latitudes.
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.
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.
Humans and monkeys are both primates. But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago.
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. The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago.
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".
blue eyes descend from a single genetic mutation means that every single person on the planet with blue eyes descended from one common ancestor. In fact, a team of geneticists at the University of Copenhagen actually traced that mutation all the way back to a single Danish family.
Humans left Africa and began dispersing throughout the world at least 120,000 years ago, but the genetic isopoint occurred much more recently—somewhere between 5300 and 2200 B.C., according to Rohde's calculations.
Health experts advise everyone, regardless of skin color, to use sunscreen with an SPF of at least 30. Although dark-skinned people won't get sunburned as quickly, they will still burn and are still susceptible to sun-induced damage—such as sun spots and wrinkles—and cancer .
Humans with dark skin have skin naturally rich in melanin (especially eumelanin), and have more melanosomes which provide superior protection against the deleterious effects of ultraviolet radiation. This helps the body to retain its folate reserves and protects against damage to DNA.
