Races are not something specifically human; races occur in a large percentage of species of animals. You can read in every textbook on evolution that geographic races of animals, when isolated from other races of their species, may in due time become new species.
Races may be genetically distinct populations of individuals within the same species, or they may be defined in other ways, e.g. geographically, or physiologically. Genetic isolation between races is not complete, but genetic differences may have accumulated that are not (yet) sufficient to separate species.
What is the difference between Race and Species? Race is a system of classification of human beings only, whereas species is the most refined division of all life forms. Race has no biological basis whereas organisms that can mate and produce offspring are classified under the same species category.
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.
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.
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 ...
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.
The world population can be divided into 4 major races, namely white/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid.
In many works of modern fantasy, elves are depicted as a race or species of pointy-eared humanoid beings.
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.
Homo bodoensis will now be used for most of the Middle Pleistocene humans from Africa and a few from southeast Europe. Most humans originating from Europe will remain classified as Neanderthals. The name “bodoensis” comes from a skull recovered in Bodo D'ar, Ethiopia.
A race or subspecies requires a degree of genetic differentiation that is well above the level of genetic differences that exist among local populations.
When two different species successfully mate, the resulting offspring is called a hybrid. Hybrids are often, but not always, sterile (think of mules). Hybrids aren't necessarily good news for a rare or threatened species.
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.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
The world's largest ethnic group is Han Chinese, constituting over 19% of the global population in 2011. In terms of the largest number of native speakers, Mandarin is the world's most spoken language.
The people of India are predominantly Caucasoid. Their features, hair texture, hairiness, the shape of the nose, mouth, and so on, are all distinctly Caucasoid. It is only in some of the far, out-of-the-way places of India, as in this country, that you find certain traces of other races.
Five Races Under One Union (Chinese: 五族協和, Japanese: 五族協和) was used as a national motto in Manchukuo, for the five ethnic groups of the Manchus, the Japanese, the Han Chinese, the Mongols and the Koreans.
Race refers to the concept of dividing people into groups on the basis of various sets of physical characteristics and the process of ascribing social meaning to those groups. Ethnicity describes the culture of people in a given geographic region, including their language, heritage, religion and customs.
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.
The first humans to leave Africa 40,000 years ago are believed to have had dark skin, which would have been advantageous in sunny climates. But humans did not uniformly develop light skin when they reached the colder regions of Europe.
All living people share exactly the same set of ancestors before the Identical Ancestors Point, all the way to the very first single-celled organism. However, people will vary widely in how much ancestry and genes they inherit from each ancestor, which will cause them to have very different genotypes and phenotypes.
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].
