Sich von dem ernähren, was regional wächst – was heute in Mode ist, war für den Urmenschen alltäglich. WissenschaftlerInnen der Senckenberg Gesellschaft für Naturforschung und der Goethe-Universität Frankfurt haben jetzt anhand von fossilem Zahnschmelz herausgefunden, dass die frühen Urmenschenarten Homo rudolfensis und sogenannte Nußknacker-Menschen Paranthropus boisei, die vor 2,4 Millionen Jahren in Malawi lebten, überraschend anpassungsfähig waren und ihren Speiseplan gemäß regionaler Ressourcen änderten.

New Technologies Challenge Old Ideas About Early Hominid Diets

New assessments by researchers using the latest high-tech tools to study the diets of early hominids are challenging long-held assumptions about what our ancestors ate, says a study by the University of Colorado Boulder and the University of Arkansas.

By analyzing microscopic pits and scratches on hominid teeth, as well as stable isotopes of carbon found in teeth, researchers are getting a very different picture of the diet habitats of early hominids than that painted by the physical structure of the skull, jawbones and teeth. While some early hominids sported powerful jaws and large molars — including Paranthropus boisei, dubbed “Nutcracker Man” — they may have cracked nuts rarely if at all, said CU-Boulder anthropology Professor Matt Sponheimer, study co-author.

The males of two bipedal hominid species that roamed the South African savannah more than a million years ago were stay-at-home kind of guys when compared to the gadabout gals, says a new high-tech study led by the University of Colorado Boulder.

The team, which studied teeth from a group of extinct Australopithecus africanus and Paranthropus robustus individuals from two adjacent cave systems in South Africa, found more than half of the female teeth were from outside the local area, said CU-Boulder adjunct professor and lead study author Sandi Copeland. In contrast, only about 10 percent of the male hominid teeth were from elsewhere, suggesting they likely grew up and died in the same area. (more…)

‘Ancient Bipedal Hominid Dubbed ‘Nutcracker Man’ Preferred Grass to Nuts’

An ancient, bipedal hominid sporting a set of powerful jaws and huge molars that earned it the nickname “Nutcracker Man” likely didn’t crack nuts at all, preferring instead to slurp up vast quantities of grasses and sedges, says a new study.

The hominid, known as Paranthropus boisei, ranged across the African landscape more than 1 million years ago and lived side-by-side with direct ancestors of humans, said University of Colorado Boulder anthropology Professor Matt Sponheimer, a study co-author. It was long assumed Paranthropus boisei favored nuts, seeds and hard fruit because of its huge jaws, powerful jaw muscles and the biggest and flattest molars of any known hominid in the anthropological record, he said.
