protoTyporian

ProtoTyporian refers to an ancient, hypothetical species from which certain modern human groups may have evolved. This concept is part of the multiregionalism hypothesis in paleoanthropology. According to the hypothesis, various distinct populations that lived in different regions of the world, such as East Asia, Africa, Australia, and Europe, contributed to the modern human gene pool.

Proponents of this theory suggest that these early human populations interbred with anatomically modern humans, Homo sapiens, to create the diverse range of populations seen today. The multiregional hypothesis argues against the "out of Africa" theory, which posits that Homo sapiens originated in Africa around 200,000 years ago and then migrated to other parts of the world, replacing or interbreeding with existing populations.

Supporters of the multiregional hypothesis point to genetic and fossil evidence that suggests early human populations were present in various regions of the world, including Asia and Europe, millions of years ago. They also argue that the preservation of ancient genotypes and phenotypes in modern populations provides evidence for interbreeding between early human populations and modern humans.

However, not all researchers accept the multiregional hypothesis, with many arguing that the genetic and fossil evidence does not support the idea of significant interbreeding between archaic human populations and modern humans. The controversy over the origins of modern human populations continues to be a topic of debate in the scientific community.
