🦎 New collaborative research from the RVC, the Institute of Vertebrate Paleontology and Paleoanthropology, and Clemson University has revealed how more upright limb postures helped ancient reptiles overcome the biomechanical constraints of body size. ➡️ https://t.co/MmQihBRtqX

Even a single gene, shuffled and regulated in new ways, can fuel repeated bursts of evolutionary innovation, according to a new Science study of wheatear birds, which exhibit distinctive black and white plumage over different areas of their bodies. https://t.co/Pd5iBh7Xyc

Snow leopards have the lowest genetic diversity of all big cats due to persistently small population sizes throughout their evolutionary history, which may make recovery from human hunting and habitat loss challenging. In PNAS: https://t.co/jFsT9CWqEF

Cool to discover, that new living fossils. One example is Hula painted frog https://t.co/SuVcOzsRRd , which is endemic to one lake in Israel and it diverge from sister in the Paleogene Apparently new (extinct) species is found in early Pleistocene of Italy https://t.co/y8re25n6Dv

#MARAVILLOSO 🤩 Una de las nevadas más grandes del año cubrió el PNNC (@ParquesColombia), dejando postales únicas registradas por los guardaparques. El Nevado del Ruiz, Santa Isabel, el Paramillo del Cisne y Santa Rosa amanecieron conectados por un mismo manto de nieve.

Is it a lizard? Is it a snake? Maybe a 'false snake'?? As that's what its name means in Gaelic! Hello to Breugnathair, a new fossil from the Jurassic of Skye with a curious mix of snake & lizard features, showing that early squamate evolution was complex https://t.co/tSNPcYZnAJ
bbc.co.uk
Experts say the lizard-like creature, which has been given the Gaelic name Breugnathair elgolensis, had lived about 167 million years ago.
