The St Bernard dog – named after the 11th century priest Bernard of Menthon – is living proof that evolution does occur, say scientists. Biologists at The University of Manchester say that changes to the shape of the breed’s head over the years can only be explained through human-directed evolution through selective breeding, an artificial version of natural selection.
When it comes to their social behavior, people sometimes act like monkeys, or more specifically, like rhesus macaques, a type of monkey that shares with humans strong tendencies for nepotism and political maneuvering, according to research by Dario Maestripieri, an expert on primate behavior and an Associate Professor in Comparative Human Development and Evolutionary Biology at the University of Chicago.
A rare Amur leopard (Panthera pardus orientalis), one of only an estimated 30 left in the wild has been captured and health-checked by experts from a consortium of conservation organizations, before being released.
When David Jones, a fisheries oceanographer at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) located at the University of Miami’s Rosenstiel School, set out to design a better light trap to collect young reef fishes, he never imagined his invention would contribute to the discovery of a new species. But, after finding a goby that didn’t quite fit any known description, his catch turned out to be the answer to another scientist’s twenty-five-year-old research conundrum. The larval stage captured in Jones’s new trap was matched to the adult form of a previously unknown species of reef fish by new DNA barcoding technology — which confirmed both were members of a new species.
