The racial diversity of Asia 's peoples, Nordisk familjebok Groups of humans have always identified themselves as distinct from neighboring groups, but such differences have not always been understood to be natural, immutable and global. They claim that "the molecular and biochemical proponents of this model explicitly use racial categories in their initial grouping of samples". The review included: 1 organizing a workshop to address the issues by the National Academy of Sciences, 2 convening four public hearings, and 3 appointing an Interagency Committee for the Review of Racial and Ethnic Standards, which later developed a research agenda and conducted several research studies. But those variations cannot be tracked to distinct biological categories. A clade is a taxonomic group of organisms consisting of a single common ancestor and all the descendants of that ancestor a monophyletic group. Brutal conflicts between ethnic groups have existed throughout history and across the world. In this way the idea of race as we understand it today came about during the historical process of exploration and conquest which brought Europeans into contact with groups from different continents, and of the ideology of classification and typology found in the natural sciences.

Generally, when it is used it is effectively a synonym of subspecies. Race and ethnicity don't show up at the genetic level, but the concept of race still forms the human experience. For instance, African-American English is a language spoken by many African Americansespecially in areas of the United States where racial segregation exists.

Another observation is that traits or alleles that vary from one group to another do not vary at the same rate. Every creature produced by sexual reproduction has two immediate lineages, one maternal and one paternal.
