Polygenism

Wikipedia's first sentence called it “biblical theory of human origins positing that the human races are of different lineages”. Today it says “theory of human origins which posits the view that humans are of different origins”. The one-line description Wikipedia serves to search engines and AI systems read “Theory of human origins”. It now reads “Theory of plural human origins”.

The opening as it read in 2005

Polygenism is a biblical theory of human origins positing that the human races are of different lineages.1 This is opposite to the idea of monogenism , which posits a single origin of humanity (i.e. Adam and Eve ) Polygenism is an uncommon Biblical interpretation . Until the mid- 1800s it was largely considered heretical . It was first raised by Isaac La Peyrère, a Dutch polymath seeking to reconcile the limited number of generations between Adam and Eve and modern day by positing "pre-adamites". It was not believed that the number of races could not have developed within the commonly accepted biblical timeframe. Voltaire even brought the subject up in Essay on the Manner and Spirit of Nations and on the Principal Occurences in History in 1756 (which was an early work of comparative history), although Voltaire made no attempt to solve the problem. Polygenism came into mainstream scientific and religious thought due to the work of Samuel George Morton and more prominently Louis Agassiz in the United States . The issue of race was polemical, and slave owners attempted to justify their treatment of slaves using empirical science .2 This group was more closely attached to Morton's work, who believe that other races were a different species mentally inferior to caucasians .3 Agassiz believed that each race was unique, but could still be classified as the same species. Contemporary geological discoveries descibed the earth as far older than the standard interpretation of Genesis allows, and among the more progressive thinkers, polygenism was a way to reconcile the new discoveries with their faith. In the race debates of the 1860s and 1870s, Charles Darwin and his supporters argued for a monogenism of the species — seeing the common origin of all humans as essential for evolutionary theory .4 This is called the single-origin hypothesis , although it is no longer acknowledged as crucial to evolution by the scientific community .5 In the late 20th century, the work of the paleoanthropologist Carleton Coon was the closest to what can be perhaps considered a "modern" polygenism by positing that the individual races of the earth separately evolved into modern homo sapiens . This hypothesis, called the multiregional hypothesis , was not very popular when it was presented in the mid-1960s.6
