Is there more genetic variation within or between races?

In 2003, Phase 1 of the Human Genome Project (HGP) demonstrated that humans populating the earth today are on average 99.9% identical at the DNA level, there is no genetic basis for race, and there is more genetic variation within a race than between them [2].

Can race be determined biologically?

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).

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. …

Who has the best genetics in the world?

Iceland’s record of low immigration and its genealogical records going back 1,000 years make it a paradise for geneticists. A third or more of the population has already donated a DNA sample – but a new push to increase that figure is meeting some resistance.

Which race is closest to Neanderthal?

Together with an Asian people known as Denisovans, Neanderthals are our closest ancient human relatives. Scientific evidence suggests our two species shared a common ancestor. Current evidence from both fossils and DNA suggests that Neanderthal and modern human lineages separated at least 500,000 years ago.

Which race has the strongest bones?

What are the 3 human races?

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. Genetic distance data indicate that Caucasoid and Mongoloid are somewhat closer to each other than to Negroid.

What is my race if I am Hispanic born in America?
