These groups form branches that form smaller branches in a process called cladogenesis.
These groups form branches that form smaller branches in a process called cladogenesis. The "ring" type of these groups is formed by their interbreeding, and natural selection may cause some of them to be reproductively isolated according to the Wallace effect. The process that forms these groups occurs in (*) sympatric, peripatric, and allopatric forms. Humans are considered part of the sapiens one. Name this taxonomic rank below genus, the lowest major taxonomic group.
