Is race a valid biologically meaningful concept?
No, race is not an appropriate, valid, or biologically meaningful concept. Traits assumed to be racial (e.g. skin color, cranial form, genetic polymorphisms) do not correlate in their distribution, which means that they are inherited independent of one another and are thus non-concordant.
What is the race concept?
race, the idea that the human species is divided into distinct groups on the basis of inherited physical and behavioral differences.
What does DNA tell us about race?
Using AIMs, scientists can determine a person’s ancestral continent of origin based solely on their DNA. AIMs can also be used to determine someone’s admixture proportions. The more individuals studied, the easier it becomes to detect distinct clusters (statistical noise is reduced).
Which race is the most genetically diverse?
Africans
New study confirms that Africans are the most genetically diverse people on Earth. And it claims to pinpoint our center of origin. Geneticists have known for some time that Africans are highly genetically diverse.
Is ancestry DNA accurate?
Reading your DNA is a first step in generating your AncestryDNA results. Accuracy is very high when it comes to reading each of the hundreds of thousands of positions (or markers) in your DNA. With current technology, AncestryDNA has, on average, an accuracy rate of over 99 percent for each marker tested.
Are humans a race or species?
Today, all humans are classified as belonging to the species Homo sapiens. However, this is not the first species of homininae: the first species of genus Homo, Homo habilis, evolved in East Africa at least 2 million years ago, and members of this species populated different parts of Africa in a relatively short time.
What race is the least genetically diverse?
Native Americans had the least genetic diversity of all, indicating that part of the world was settled last.
