The origins of Atlantic and Asian Creoles (monogenetic hypothesis)
In the modern creolistics there exist diverse hypotheses or theories on the origin and formation of pidgins and Creole languages. Two of them appear to be the most fundamental and most discussed ones among researchers in this field. The first classical theory, called polygenetic, is based on a hypothesis of the parallel processes of structural simplification of the donor language. The other theory, shared by many researchers and called monogenetic, postulates a common derivation of all Creole languages in Africa, America and Asia from one proto-Creole, identified with a Portuguese Creole developed along the West Coast of Africa in the 15th century.
