Bigger Really Was Better For Early Prehistoric Life
2014-01-24 14:38:14

[ Watch the Video: The Evolution of the World’s Oldest Fossil Communities ] University of Toronto A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals. Laflamme, an assistant professor with the Department of Chemical and Physical Sciences, and his colleagues at the Massachusetts Institute of Technology Node of NASA's Astrobiology Institute suggest that height...

As mating season approaches, male animals are faced with a question that can make or break their chances at reproducing: does it pay to be a lover or a fighter? Or both? Researchers from The University of Manchester and Syracuse University in New York working with the University of Western Australia, found that where animals fall on the lover/fighter scale depends on how much they are able to ensure continued mating rights with females. In species where fighting for the right to mate...

Flies That Live With Their Brothers Are Gentler Lovers
2014-01-23 13:39:47

University of Oxford Flies living with their brothers cause less harm to females during courting than those living with unrelated flies, say Oxford University scientists. The study, published this week in Nature, found that unrelated male flies compete more fiercely for females' attention than related flies, resulting in shorter lifespans for males and reduced fecundity for females. "In large populations brothers don't need to compete so much with each other for female attention...

Genes And Calls Reveal Greater Diversity Of Amazon Frog Species
2014-01-15 15:12:22

Pensoft Publishers Amazonian biodiversity has been studied for hundreds of years. Early explorers of Amazonian plants and animals included renowned naturalists of the stature of Alexander von Humboldt and A. R. Wallace. Despite this long history of exploration, new studies are resulting in the discovery of a large number of new species. The key of these discoveries lies in the use of advanced new tools for species detection. The study, published in the open access journal ZooKeys, found...

Single cell analysis captures a genomic phenomenon that fuels the complexity and diversity of living things A Ludwig Cancer Research study has uncovered a phenomenon that alters prevailing views of how the genome is expressed to make and sustain the life of mammals. Published in the journal Science, the paper helps explain why genetically identical animals are sometimes so different in their biology and appearance, and why some inherited disorders caused by a shared set of aberrant genes...

Press release from PLOS Computational Biology Scientists have demonstrated that organisms with greater complexity are more likely to evolve in complex environments, according to research published this week in PLOS Computational Biology. The researchers, based at École Polytechnique Fédérale de Lausanne and University of Vermont, created a programme that simulated the evolution of virtual creatures in a variety of landscapes. Each virtual organism was made using a particular form of...

Agricultural Antibiotics User Fee
2013-12-26 09:34:36

Brett Smith for redOrbit.com - Your Universe Online For years, public health officials have been calling for a reduction of the use of antibiotics in the food production industry, citing minimal benefit to the process and the increased risk of fostering antibiotic-resistant strains of harmful bacteria. Instead of calling for a ban on the non-medicinal use of antibiotics, a report published on Thursday in the New England Journal of Medicine recommended imposing a user fee “just as...

Evolution Of Species Does Not Always Follow Darwin's Theories
2013-12-23 04:19:44

redOrbit Staff & Wire Reports - Your Universe Online Evolutionary scientists have long argued that species that live together must evolve in different ways in order to avoid direct competition with each other, but new research published Sunday in the journal Nature suggests otherwise. A team of researchers led by Dr. Joe Tobias of Oxford University's Department of Zoology studied ovenbirds, one of the most diverse families of birds in the world, in order to conduct an in-depth...

Researchers Create Largest Evolutionary 'Timetree' of Land Plants; Results Published in Nature WASHINGTON, Dec. 22, 2013 /PRNewswire-USNewswire/ -- A team of researchers studying plants has assembled the largest dated evolutionary tree, using it to show the order in which flowering plants evolved specific strategies, such as the seasonal shedding of leaves, to move into areas with cold winters. The results will be published Dec. 22 in the journal Nature. Early flowering plants are thought to...

Top Researchers Brought Together To Sequence Genomes Of Invertebrates
2013-12-13 13:45:51

Nova Southeastern University NSU professor organized and hosted first-ever workshop with experts from across the globe Pop Quiz: what creatures make up more than 70% of the approximately 1.9 million described species on earth and have long served as model organisms in many areas of biology? If you guessed invertebrates, you're right! To begin exploring this question, a new cooperative consortium called the Global Invertebrate Genomics Alliance (GIGA) was formed and held its inaugural...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
