Concept of Race Biological concept: race as a biological concept may signify genetically divergent human populations that can be marked by common phenotype. Essentialist concept: a broad division of mankind characterized as a group, sharing certain combinations of features derived from their common descent and constitute a vague physical background. Taxonomic concept: race as a subspecies is an aggregate of phenotypically similar sub-populations of a species, inhabiting a geographic subdivision differing taxonomically from other populations of the species. Population concept: race as genetically distinct human populations, they may exhibit individuals who look alike physically and culturally. Genetical concept: a population which differs in the frequency of some gene or genes which actually exchanges genes among its members. Lineage concept: a subspecies is a distinct evolutionary lineage within a species. The subspecies is genetically differentiated due to barriers causing changes that have persisted for long periods. Criteria for racial classification: Phenotypic traits Physical characteristics which observable, but not necessarily inheritable. Racial Classification Measurable Traits: Color of skin, hair, etc. Definite: These traits can be measured with the help of instruments. E.g., Structure of head. Genotypical Traits: Some of the genetic traits that classify human races are blood groups, DNA, fingerprint. Racial Classification Caucasoid: This race is characterized by light skin color, medium built, found in Spain, British. Mongoloid: Yellow or light wheatish color skin, black hair, eyes, found in China, Japan. Negroid: Found in African. Australoid: Found in Australia.
