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 ...
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.
Scientists are sure that Homo sapiens first evolved in Africa, and we know that every person alive today can trace their genetic ancestry to there. It has long been thought that we began in one single east or south African population, which eventually spread into Asia and Europe.
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.
We are now the only living members of what many zoologists refer to as the human tribe, Hominini, but there is abundant fossil evidence to indicate that we were preceded for millions of years by other hominins, such as Ardipithecus, Australopithecus, and other species of Homo, and that our species also lived for a time ...
The first organized automobile competition, a reliability test in 1894 from Paris to Rouen, France, a distance of about 80 km (50 mi), was won with an average speed of 16.4 kph (10.2 mph). In 1895 the first true race was held, from Paris to Bordeaux, France, and back, a distance of 1,178 km.
Abstract. Using gene frequency data for 62 protein loci and 23 blood group loci, we studied the genetic relationship of the three major races of man, Caucasoid, Negroid, and Mongoloid.
The myth that Adam and Eve were the first man and women on Earth may have been proved true — as all humans are descendants of a single couple, scientists say.
Homo erectus characteristics
erectus is the oldest known species to have a human-like body, with relatively elongated legs and shorter arms in comparison to its torso.
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.
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.
Answer and Explanation: Yes, the first humans were almost certainly black. The human species evolved in East Africa about 200,000 years ago. Black skin was necessary for survival in this hot and sunny climate.
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.
Researchers discovered the ancient pink pigments in 1.1-billion-year-old rocks deep beneath the Sahara Desert in the Taoudeni Basin of Mauritania, West Africa, making them the oldest colors in the geological record.
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.
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.
When I drew up a family tree covering the last one million years of human evolution in 2003, it contained only four species: Homo sapiens (us, modern humans), H. neanderthalensis (the Neanderthals), H. heidelbergensis (a supposedly ancestral species), and H. erectus (an even more ancient and primitive species).
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.
Some experts believe that practically everyone alive with British ancestry will have a connection with this king. So statistically, there is a good chance that you are descended from royalty. This may not be from the direct, legitimate line so you may be at some remove from the throne.

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.
Biologists estimate that any two people on Earth share 999 out of every 1,000 DNA bases, the “letters” of the genetic code. Within the human population, all genetic variations—the inheritable differences in our physical appearance, health, and personality—add up to just 0.1 percent of about 3 billion bases.
Australoid race was a word for the aboriginal people of Australia, Melanesia, and parts of Southeast Asia. In former times, many people divided human beings into four races. These races were called Australoid, Mongoloid, Caucasoid, and Negroid.
OMB requires five minimum categories (White, Black or African American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander) for race. OMB permits the Census Bureau to also use a sixth category - Some Other Race. Respondents may report more than one race.
