A normal adult human skeleton consists of 206 named bones (or 213 if each of the nine fused vertebrae of the sacrum and coccyx are counted as independent bones). The individual bones of the skeleton are connected by three types of joints, which differ in the type and amount of movement they allow. The human skeleton is divided functionally into an axial skeleton that supports the main body axis and an appendicular skeleton that supports the arms and legs.

Haplogroup A (M91) is found in Africa (especially the Khoisan, Ethiopians, and Nilotes). In human genetics, Haplogroup A is the lineage of most human males. No mutations define Haplogroup A, but since this nomenclature only deals with Homo sapiens, the hypothetical "Y-chromosomal Adam" can be considered its founder.
