Enamel Proteins From Paranthropus Robustus Teeth Reveal Biological Sex and Genetic Variability

Enamel proteins from Paranthropus robustus teeth reveal biological sex and genetic variability

A large international team of anthropologists, evolutionary theorists, biologists, and historians has identified gender and genetic variability via sequencing of enamel proteins from four Paranthropus robustus teeth within the species. In their study, published in the journal Science, the group analyzed proteins preserved in the fossilized tooth enamel of ancient hominins.

Males weren’t always bigger than females in this hominid species

Molecular evidence from a 2-million-year-old southern African hominid species indicates sex and genetic differences in P. robustus.

The history of human evolution has just been rewritten thanks to a revolutionary technique that surpasses the limits of ancient DNA: paleoproteomics. An international team of scientists has managed to extract and analyze proteins from tooth enamel from four fossils of Paranthropus robustus, a hominid that inhabited South Africa between 2.8 and 1.2 million years ago.The results, published in Science, not only confirm the biological sex of these i…

A team of European and African researchers used a method known as paleoproteomics to retrieve fragments of four-toothed tooth enamel proteins found in Swartkrans cave in South Africa and belonged to an early human named Paranthropus robustus. They used state-of-the-art mass spectrometry techniques to reconstruct [...]

An ancient and distant human cousin from southern Africa called Parathropus robustus has for the first time revealed molecular indices of its evolutionary status. Protein Sequences conserved in four parts P. robustus The teeth of different individuals who lived about 2 million years ago indicate that larger and smaller fossils [...]

The size of males in this ancient human family did not always correspondhydrated females, in fact the females were never the biggest mammals

The evolutionary status of Paranthropus robustus, an ancient, distant human cousin from southern Africa, has been provided for the first time by...
