Cranial cresting patterns and their significance in the Hominoidea. In view of recent suggestions that tooth and jaw reduction in the hominid line was due to random mutation, it is pointed out that positive selective factors, involving greater chewing efficiency and increased speed in movements of the head, may have been at work.

Among other techniques, the researchers used synchrotron X-ray imaging to look inside the fossil to see the internal structure of the teeth, including growth lines that revealed the rate of tooth development. (Debbie Guatelli-Steinberg / OSU). Late Miocene fossil hominid teeth recovered from Ethiopia's Middle Awash are assigned to Ardipithecus kadabba . While the dental development of this juvenile suggested it had a slow life course similar to modern humans, Guatelli-Steinberg cautioned that we don't know what happens in later childhood in hominins like this one.

Over time the rear teeth of Paranthropus … Another aspect that was similar to modern humans was the perikymata, which are the incremental growth lines that appear on the surface of the tooth. "This juvenile had a 10-day rhythm, which you don't see very often in early hominins," she said. Evolution is a simple term for change that occurs with respect to time as species are adjusted and diverge to create numerous descendant species. Learn about our remote access options. Instead, hominid evolution produced a dense thicket of branches, with several species co-existing at any given time except for the last 30,000 years or so. That's because growth lines in teeth retain a record of dental development. 3 Problems to Remember When Trying to Find Atlantis, Archaeologists Find Medieval Dentures Made from the Teeth of Dead People, New Studies Clash with Previous Analyses On the Life and Fate of Neanderthals, Oldest Human DNA Reveals Mysterious Branch of Humanity, An ancient relative of humans shows a surprisingly modern trait: Study finds an archaic hominin had modern dental growth.".
