Did primitive humans have an under-bite?

Primitive humans likely exhibited a range of dental traits, including variations in jaw structure like underbites, due to evolutionary adaptations to their diets and environmental factors. Their diets, which included tougher foods, may have influenced jaw development over time. Additionally, the prevalence of dental issues, including underbites, can vary based on genetics and lifestyle, meaning some individuals may have had an underbite while others did not. Overall, while some primitive humans may have had underbites, it was not a universal characteristic.
