Swedish, Australian and French researchers present for the first time miraculously preserved musculature of 380 million year old armoured fish discovered in north-west Australia. This research will help scientists to better understand how neck and abdominal muscles evolved during the transition from jawless to jawed vertebrates. The scientific paper describing the discovery is published today in the journal Science. http://phys.org/news290349365.html Other Sciences Thu, 13 Jun 2013 14:00:03 EST news290349365 (Phys.org) —An unusual fossil fish that has fins behind its anus could have implications for human evolution according to a scientist at The University of Manchester. http://phys.org/news284801474.html Other Sciences Wed, 10 Apr 2013 08:31:20 EST news284801474 Scientists who famously discovered the lobe-finned fish fossil Tiktaalik roseae, a species with some of the clearest evidence of the evolutionary transition from fish to limbed animals, have described another new species of predatory fossil lobe-finned fish fish from the same time and place. By describing more Devonian species, they're gaining a greater understanding of the "fish-eat-fish world" that drove the evolution of limbed vertebrates. http://phys.org/news283601639.html Other Sciences Wed, 27 Mar 2013 11:14:05 EST news283601639 (Phys.org) —Researchers from The Australian National University (ANU) working on the New South Wales south coast have discovered a new species of ancient fish, after unearthing the largest fossilised lobe-finned fish skull ever found in rocks of Devonian age. The descendants of these ancient fish evolved into the first land animals. http://phys.org/news281875833.html Other Sciences Thu, 07 Mar 2013 10:50:40 EST news281875833 (Phys.org)—A seven million-year-old South American fossil from a species known as Arrhinolemur scalabrinii – which translates literally to "Scalabrini's lemur without a nose" – has long been a curiosity because there is only one specimen in existence and it is unlike most other primates. http://phys.org/news268556468.html Other Sciences Thu, 04 Oct 2012 08:01:21 EST news268556468 Those delicious flatfishes, like halibut and sole, are also evolutionary puzzles. Their profoundly asymmetrical heads have one of the most unusual body plans among all backboned animals (vertebrates) but the evolution of their bizarre anatomy has long been a mystery. How did flatfishes, with both of their eyes on one side of their head, evolve? So puzzling was the anatomy of flounders and their kin that they were used in early arguments against Darwin and his theory of natural selection. Skeptics wondered how such unusual features could have slowly evolved whilst remaining advantageous for the fishes' survival. http://phys.org/news259858697.html Other Sciences Mon, 25 Jun 2012 16:00:03 EST news259858697 The common ancestor of all jawed vertebrates on Earth resembled a shark, according to a new analysis of the braincase of a 290-million-year-old fossil fish that has long puzzled paleontologists. http://phys.org/news258806632.html Biology Wed, 13 Jun 2012 13:00:07 EST news258806632 An ancient group of African fish known as bichirs were examined by scientists seeking a better understanding of the development of early vertebrates. http://phys.org/news258363403.html Biology Fri, 08 Jun 2012 08:36:54 EST news258363403 A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians. This theorized image of such a drastic adaptation to changing environmental conditions, however, may, itself, be evolving into a new picture. http://phys.org/news244225936.html Other Sciences Tue, 27 Dec 2011 16:32:23 EST news244225936 The history of evolution is periodically marked by explosions in biodiversity, as groups of species try out a wide range of shapes and sizes. With a new analysis of two such adaptive radiations in the fossil record, researchers have discovered that these diversifications proceeded head-first. http://phys.org/news243621512.html Biology Tue, 20 Dec 2011 20:00:01 EST news243621512 (PhysOrg.com) -- New University of Florida research puts to rest the mystery of where old carbon was stored during the last glacial period. It turns out it ended up in the icy waters of the Southern Ocean near Antarctica. http://phys.org/news207239244.html Space & Earth Mon, 25 Oct 2010 15:27:55 EST news207239244 (PhysOrg.com) -- A 380-million-year-old fossil fish that shows an unborn embryo and umbilical cord has been discovered, scientists report in the journal Nature. http://phys.org/news154796016.html Biology Wed, 25 Feb 2009 14:54:04 EST news154796016 In an article in today's Nature, Uppsala researcher Martin Brazeau describes the skull and jaws of a fish that lived about 410 million years ago. The study may give important clues to the origin of jawed vertebrates, and thus ultimately our own evolution. http://phys.org/news151235468.html Other Sciences Thu, 15 Jan 2009 09:51:08 EST news151235468
