There is a great deal of scientific controversy surrounding whether:​

A) ​Neandertals existed outside of modern-day Europe
B) ​anatomically modern humans are related to Neandertals
C) ​there is a genetic relationship between Homo erectus and Neandertals
D) ​genetic ancestry between Homo habilis and anatomically modern humans exists

Anatomically Modern Humans

Neandertals
