(PhysOrg.com) -- Ancient DNA retrieved from extinct horse species from around the world has challenged one of the textbook examples of evolution - the fossil record of the horse family Equidae over the past 55 million years. http://www.physorg.com/news179653662.html Biology Thu, 10 Dec 2009 08:40:01 EST news179653662 (PhysOrg.com) -- A Massey biology researcher has used DNA analysis to prove quail on Tiritiri Matangi Island are Australian and not remnants of an extinct New Zealand species. http://www.physorg.com/news175507924.html Biology Fri, 23 Oct 2009 09:12:40 EST news175507924 (PhysOrg.com) -- Genetic information from an extinct species of bison preserved in permafrost for thousands of years could help improve modern agricultural livestock and breeding programs, according to University of Adelaide researchers. http://www.physorg.com/news175251993.html Biology Tue, 20 Oct 2009 10:07:02 EST news175251993 (PhysOrg.com) -- DNA study suggests that further waves of prehistoric immigration are waiting to be discovered. Central and northern Europe's first farmers were immigrants with barely any ancestral ties to the modern population, a study has found. http://www.physorg.com/news171208706.html Other Sciences Thu, 03 Sep 2009 15:50:02 EST news171208706 (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 Wild horses were domesticated in the Ponto-Caspian steppe region (today Russia, Kazakhstan, Ukraine, Romania) in the 3rd millennium B.C. Despite the pivotal role horses have played in the history of human societies, the process of their domestication is not well understood. http://www.physorg.com/news159714951.html Biology Thu, 23 Apr 2009 14:16:34 EST news159714951 In a new study published April 1 in the online, open-access, peer-reviewed journal PLoS ONE, ancient DNA (aDNA) is retrieved from various insect remains without destruction of the specimens. http://www.physorg.com/news157786307.html Biology Wed, 01 Apr 2009 06:32:24 EST news157786307 Scientists at deCODE genetics have completed the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains, the study provides a detailed look at how a contemporary population differs from that of its ancestors. The study is published January 16 in the open-access journal PLoS Genetics. http://www.physorg.com/news151318424.html Medicine & Health Fri, 16 Jan 2009 08:53:44 EST news151318424 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 The study of ancient microbes may not seem consequential, but such pioneering research at the University of Oklahoma has implications for the state of modern human health. Cecil Lewis, assistant professor in the Department of Anthropology, says results of this research raise questions about the microbes living on and within people. http://www.physorg.com/news150397619.html Medicine & Health Mon, 05 Jan 2009 17:06:59 EST news150397619
