A second definition defines races as distinct evolutionary lineages within a species . An evolutionary lineage is a population of organisms characterized by a continuous line of descent such that the individuals in the population at any given time are connected by ancestor/descendent relationships.
What is the origin of the races?
The idea of “race” began to evolve in the late 17th century , after the beginning of European exploration and colonization, as a folk ideology about human differences associated with the different populations—Europeans, Amerindians, and Africans—brought together in the New World.

What is the role of evolution in the history of human race?
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.
How did human races evolve?
Anthropologists support the idea that anatomically modern humans (Homo sapiens) evolved in North or East Africa from an archaic human species such as H. heidelbergensis and then migrated out of Africa , mixing with and replacing H. heidelbergensis and H. neanderthalensis populations throughout Europe and Asia, and H. ...
What are the 5 races of humans?

When 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.
