Hello, Our paper on enamel proteins from Paranthropus robustus has finally been peer reviewed, please have a read here: www.science.org/doi/10.1126/... Paranthropus robustus has been puzzling scientists since its discovery in 1938 in South Africa, where a high number of fossils have been found.

Enamel proteins reveal biological sex and genetic variability in southern African Paranthropus
Paranthropus robustus is a morphologically well-documented Early Pleistocene hominin species from southern Africa with no genetic evidence reported so far. In this work, we describe the mass spectrome...

Thank you, Frido! It was a really nice experience for me, and I enjoyed working with wonderful colleagues in Copenhagen. This research would not have been possible without the contributions of everyone involved.
