Just published in Science Magazine: ancient proteins show that the Penghu 1 mandible from Taiwan belongs to a male Denisovan. They weren't just in Siberia or Tibet. Open access article: science.org/doi/10.1126/sc… #HumanEvolution #Denisovan #Paleoanthropology #AncientProteins

Introducing Mosura fentoni, a new radiodont from the #BurgessShale. Paper here: doi.org/10.1098/rsos.2… This #fossil species has 3 eyes, spiny claws, wing-shaped swimming flaps, and a unique abdomen-like body region.

Ancient sloths ranged in size from tiny climbers to ground-dwelling giants. Now, researchers report in Science that this body size diversity was largely shaped by sloths’ habitats, and that these animals’ precipitous decline was likely a result of increasing human pressures.

"Humans evolved to survive mild burns at the expense of severe ones" My take and that of Thomas Püschel at the end of the article newscientist.com/article/247811…

Our latest, led by James Clark of Milner Centre for Evolution shows that the notorious mismatch between molecular and palaeontological estimates for the timing of origin of flowering plants is a consequence of the equivocal interpretation of their fossil record royalsocietypublishing.org/doi/10.1098/rs…
