Polygenism is a theory of human origins which posits the view that the humans are of different origins (polygenesis). This view is opposite to the idea of monogenism, which posits a single origin of humanity. Modern scientific views find little merit in any polygenic model due to an increased understanding of speciation in a human context, with the monogenic "Out of Africa" hypothesis and its variants being the most widely accepted models for human origins.[1] Polygenism has historically been heavily used in service of white supremacist ideas and practices, denying a common origin between European and non-European peoples.[2][3] It can be distinguished between Biblical polygenism, describing a Pre-Adamite or Co-Adamite origin of certain races in the context of the Genesis narrative of Adam and Eve, and scientific polygenism, attempting to find a taxonomic basis for ideas of racial science.
