Neanderthal dentition
Sep 13, 2023 · Key Points. Neanderthals lived between 200,000 and 30,000 years ago. Neanderthal teeth matured much faster than modern humans do. These ancient humans had large shovel-like front teeth. They had larger pulp chambers and tooth root. It was common to lose teeth throughout their lifetime. We used a Bayesian statistical approach to classifying individuals into ‘modern’ and ‘non-modern’ groups based on dental non-metric traits . The classification was based on dental trait frequencies for two ‘known’ samples of 109 Upper Paleolithic H. sapiens and 129 Neanderthal individuals. A cross-validation test of these ...

Question Using the 3-D models and list of cranial traits, describe the general cranial morphology for H. neanderthalensis. Be sure to describe at least three cranial traits of H. neanderthalensis (i.e., skull size/morphology, prognathism, occipital anatomy, forehead, or dentition). (Minimum of 2 complete sentences.) Expert SolutionMar 5, 2015 · Another interesting difference is that by studying neanderthal teeth, researchers have concluded that neanderthals mature much faster than humans, reaching maturity at 15 years old. They also had higher mortality rates and shorter life span than anatomically modern humans possibly due to physical stress. Studies of the wear patterns reveal that Neandertals wore down their front teeth more than their cheek teeth—indicating they used their incisors and canines as a third hand to grip and...
