(PhysOrg.com) -- Scientists have performed the first DNA-based reconstruction of the giant extinct moa bird, using prehistoric feathers recovered from caves and rock shelters in New Zealand. http://www.physorg.com/news165554733.html Biology Wed, 01 Jul 2009 09:00:01 EST news165554733 New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to landlubber. http://www.physorg.com/news159190294.html Other Sciences Fri, 17 Apr 2009 12:32:10 EST news159190294 By comparing the craniodental morphology of modern bear species to that of two extinct species, researchers from the University of Málaga, Spain, have discovered that the expired plantigrades were not so different from their current counterparts. The cave bear, regarded as the great herbivore of the carnivores, was actually more omnivorous than first thought. The short-faced bear, a hypercarnivore, also ate plants depending on their availability. The work offers key insights into the evolution of the carnivore niches during the Ice Age. http://www.physorg.com/news158489644.html Biology Thu, 09 Apr 2009 09:54:26 EST news158489644 All the genes that the exotic Tasmanian Tiger inherited only from its mother will be revealed by an international team of scientists in a research paper to be published on 13 January 2009 in the online edition of Genome Research. The research marks the first successful sequencing of genes from this carnivorous marsupial, which looked like a large tiger-striped dog and became extinct in 1936. The research also opens the door to the widespread, nondestructive use of museum specimens to learn why mammals become extinct and how extinctions might be prevented. http://www.physorg.com/news151002115.html Biology Mon, 12 Jan 2009 17:01:55 EST news151002115 (PhysOrg.com) -- A treasure trove of information about pre-human New Zealand has been found in faeces from giant extinct birds, buried beneath the floor of caves and rock shelters for thousands of years. http://www.physorg.com/news150976795.html Biology Mon, 12 Jan 2009 09:59:55 EST news150976795
