The lists are commonly used in economics literature to compare the levels of ethnic, cultural, linguistic and religious fractionalization in different countries. [1] [2] Fractionalization is the probability that two individuals drawn randomly from the country's groups are not from the same group (ethnic, religious, or whatever the criterion is).
While some countries make classifications based on broad ancestry groups or characteristics such as skin color (e.g., the white ethnic category in the United States and some other countries), other countries use various ethnic, cultural, linguistic, or religious factors for classification. Ethnic groups may be subdivided into subgroups, which ...
South Asia, located on the crossroads of Western Eurasia and Eastern Eurasia, accounts for about 39.49% of Asia's population, [1] and over 24% of the world's population. [2] It is home to a vast array of people who belong to diverse ethnic groups, who migrated to the region during different periods of time. [3]
The natural world has several ways of preserving or increasing genetic diversity. Among oceanic plankton, viruses aid in the genetic shifting process. Ocean viruses, which infect the plankton, carry genes of other organisms in addition to their own. When a virus containing the genes of one cell infects another, the genetic makeup of the latter ...
Henn et al. (2011) found that the ǂKhomani San, as well as the Sandawe and Hadza peoples of Tanzania, were the most genetically diverse of any living humans studied. This high degree of genetic diversity hints at the origin of anatomically modern humans. [25] [26]
The Human Genome Diversity Project (HGDP) was started by Stanford University's Morrison Institute in 1990s along with collaboration of scientists around the world. [1] It is the result of many years of work by Luigi Cavalli-Sforza, one of the most cited scientists in the world, who has published extensively in the use of genetics to understand human migration and evolution.
A graphical representation of the typical human karyotype The human mitochondrial DNA. Human genetic variation is the genetic differences in and among populations.There may be multiple variants of any given gene in the human population (), a situation called polymorphism.
Genetic studies on Arabs refers to the analyses of the genetics of ethnic Arab people in the Middle East and North Africa.Arabs are genetically diverse as a result of their intermarriage and mixing with indigenous people of the pre-Islamic Middle East and North Africa following the Arab and Islamic expansion.
