Hypotheses abound about the reasons for this lack of room, including changes in diet and living conditions for people. Patterns of molar wear in hunter–gatherers and agriculturalists. The article, originally titled ‘ An ancient relative of humans shows a surprisingly modern trait: Study finds an archaic hominin had modern dental growth." Humans in today’s world usually do not have room to accommodate the four additional wisdom teeth that typically erupt in early adulthood. However, evidence from the middle to late Miocene shows that tooth size, by itself, cannot pinpoint the initial change to a hominid diet, at least not with the samples at hand. Cranial capacity: the capacity or size of the brain case and therefore the brain. 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.
