Analysis of H. heidelbergensis skeletons have led researchers to find that the jaw of the species featured new traits in the form of taurodont molars, a reduced M3 molar, and a large buccal cusp in the P3 premolar. [16] In general, when compared to humans, H. heidelbergensis shows a larger jaw and smaller teeth. [17]
The characteristics of the lower jaw are therefore the lack of a chin on the one hand and on the other it is the considerable size of the lower jaw bone, on which, behind the wisdom tooth a fourth premolar would easily have had space to develop.
The Jew's harp, also known as jaw harp, juice harp, or mouth harp, [nb 1] is a lamellophone instrument, consisting of a flexible metal or bamboo tongue or reed attached to a frame. Despite the colloquial name, the Jew's harp most likely originated in Siberia , specifically in or around the Altai Mountains , and is of Turkic origin.
The appearance of the early vertebrate jaw has been described as "a crucial innovation" [25] and "perhaps the most profound and radical evolutionary step in the vertebrate history". [26] [27] Fish without jaws had more difficulty surviving than fish with jaws, and most jawless fish became extinct during the Triassic period.
In jawed vertebrates, the mandible (from the Latin mandibula, 'for chewing'), lower jaw, or jawbone is a bone that makes up the lower – and typically more mobile – component of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing joints with the cranium's temporal bones.

The general trend of jaw and oral cavity shrinkage, as well as dental malocclusion presence, has been observed in burial remains across Eurasia.Analyses of remains from areas thought to be in situ (origin) to agriculture, such as those in the Levant region dated to approximately 12,000 years ago, are thought to be where humans first changed from hunting and gathering to a more agricultural ...
