Neanderthal
Artist's rendering of Homo neanderthalensis, who ranged from western Europe to Central Asia for some 100,000 years before dying out approximately 30,000 years ago.
No, Neanderthals did not have chins like modern humans. While modern humans (Homo sapiens) are characterized by a distinct mental trigone, or chin, the lower jaw of a Neanderthal was robustly built and displayed a receding chin.12
This feature is one of the morphological traits used to distinguish Neanderthal fossils from those of early modern humans. In contrast, the development of a clearly defined chin is considered a uniquely human trait that emerged as the face receded beneath the forehead during the course of human evolution.3
