Why do we have different races?
Each adaptive trait in humans has its own geographical distribution that reflects the distribution of the underlying environmental factor for which it is adaptive. The discordance in the distributions of adaptive traits in humans means that different adaptive traits will define different ecotypes/”races”.
How did humans split into races?
Genetic distance estimates suggest that among the three major races of man the first divergence occurred about 120,000 years ago between Negroid and a group of Caucasoid and Mongoloid and then the latter group split into Caucasoid and Mongoloid around 60,000 years ago.
Where did race originally come from?

What are the original races?
Some scientists spoke of three races of mankind: The Caucasian race living in Europe, North Africa and West Asia, the Mongoloid race living in East Asia, Australia, and the Americas, and the Negroid race living in Africa south of the Sahara. Other scientists had different ideas and spoke of four or five races.
Is race a biological construct?
As with other race-related questions, the answer is multi-dimensional and may well depend on whom you ask. In the biological and social sciences, the consensus is clear: race is a social construct, not a biological attribute. Today, scientists prefer to use the term “ancestry” to describe human diversity (Figure 3).
Who is the oldest race in the world?
An unprecedented DNA study has found evidence of a single human migration out of Africa and confirmed that Aboriginal Australians are the world’s oldest civilization.

What was the first race ever?
In 1895 the first true race was held, from Paris to Bordeaux, France, and back, a distance of 1,178 km. The winner made an average speed of 24.15 kph.
What was the first human race?
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. The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago.
Where did Caucasian come from?
The use of Caucasian to mean white was popularized in the late 18th century by Johann Friedrich Blumenbach, a German anthropologist, who decreed that it encompassed Europeans and the inhabitants of a region reaching from the Obi River in Russia to the Ganges to the Caspian Sea, plus northern Africans.
