Speciation Theory Questioned
2013-09-03 14:24:14

Brett Smith for redOrbit.com - Your Universe Online While scientists have catalogued millions and millions of species, there is still no agreement on how exactly new species form. However, a new study published this week in Proceedings of the National Academy of Sciences could deal a major blow to one prevailing theory - namely, that new species arise when a barrier prevents reproduction between populations. Species-creating barriers could be physical, such as a mountain range, or they...

Concealed within the vastness of the human genome, (comprised of some 3 billion base pairs), mutations are commonplace. While the majority of these appear to have neutral effect on human health, many others are associated with diseases and disease susceptibility. Reed Cartwright, a researcher at Arizona State University's Biodesign Institute, along with colleagues at ASU, Washington University and the Wellcome Trust Sanger Institute, Cambridge, UK, report on a new software tool known as...

Story Of Ancient Invasive Species North America
2013-08-22 11:59:50

Brett Smith for redOrbit.com - Your Universe Online A new study from researchers at Ohio State University tells the story of an invasion and domination that took place around 450 million years ago in North America. During the Ordovician period, a dramatic ecological shift occurred near what are now the Appalachian Mountains, as represented in the fossil record. In the study, which was published recently in the journal PLOS ONE, Ohio State paleontologists provide evidence of significant...

From frogs to humans, selecting a mate is complicated.  Females of many species judge suitors based on many indicators of health or parenting potential. But it can be difficult for males to produce multiple signals that demonstrate these qualities simultaneously. In a study of gray tree frogs, a team of University of Minnesota researchers discovered that females prefer males whose calls reflect the ability to multitask effectively.  In this species (Hyla chrysoscelis) males produce...

Ancient Mammals Evolution Mass Extinction
2013-08-14 09:52:22

Brett Smith for redOrbit.com - Your Universe Online With the continuous expansion of human activity around the world, many species are facing the increasing threat of extinction as their habitats shrink and shift. Yet life on planet Earth has faced even larger extinction threats in the past. A new study int the journal Proceedings of the Royal Society B examines how a group of mammalian relatives called anomodonts coped with a mass extinction event of the prehistoric past as a way to...

Fossil And Molecular Evidence Important For Studying Evolution
2013-08-10 05:19:24

redOrbit Staff & Wire Reports - Your Universe Online The fossils of microscopic aquatic creatures, whose shells resemble grains of sand to the naked eye, could help shed new light on the process of evolution, according to new research published Friday in the journal Methods in Ecology & Evolution. As part of their research, University of Southampton evolutionary ecologist Dr. Thomas Ezard and his colleagues are analyzing the remains of the one-millimeter large planktonic...

Feathered Dinosaurs Developed Larger Brains Before Actually Taking Flight

[ Watch the Video: CT Scan of Albatross Brain ] redOrbit Staff & Wire Reports - Your Universe Online Feathered dinosaurs actually developed the larger brains needed for flight before actually taking to the skies, according to a new study published Wednesday in the journal Nature. In the study, lead author Amy Balanoff, a research associate at the American Museum of Natural History and a postdoctoral researcher at Stony Brook University, and her colleagues, used CT scans to...

Origins Of Life On Earth May Help Hunt For Life On Other Planets
2013-07-31 10:19:02

Brett Smith for redOrbit.com - Your Universe Online Tracing the origins of life isn't only central to understanding our own history, it can also be important for discovering life on other planets. Two recently published papers -- 'Beating the acetyl coenzyme A-pathway to the origin of life' and 'The inevitable journey to being' -- in the Philosophical Transactions of the Royal Society B add supporting details to the theory life on Earth began near hydrothermal vents in the ocean floor....

John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American Paleontologist who was greatly influential in the revival of scientific research on Dinosaurs. He is best known for demonstrating that Dinosaurs were less like contemporary reptiles but more closely related to large, flightless birds like the ostrich – a theory that holds its ground in the paleontological community to this day. John Ostrom was born and raised in Schenectady, New York. His father was a physician, and...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
