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
2013-08-01 05:02:29

[ 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....

Monogamy Evolved As A Mating Strategy
2013-07-30 05:38:41

redOrbit Staff & Wire Reports - Your Universe Online The evolution of monogamy among male mammals appears to have been triggered by the threat of infants being killed by unrelated males, researchers reported on Monday in the journal PNAS. The study is the first to reveal this evolutionary pathway for the emergence of pair living, and contradicts the theory monogamy resulted from a need for extra parental care by the father. The researchers also found males were more likely to...

DNA Detection Breakthrough Could Lead To Improved Tuberculosis Treatments
2013-07-29 13:22:02

Brett Smith for redOrbit.com - Your Universe Online Minor mutations in DNA code can make for major malfunctions, and a breakthrough technique has allowed scientists to spot genetic changes with greater precision than ever. According to a new report in the journal Nature Chemistry, the new method can look at a specific DNA sequence and pull out a single mutation. "We've really improved on previous approaches because our solution doesn't require any complicated reactions or added...

Genetic Hitchhikers Picked Up By Evolution
2013-07-23 11:01:42

Princeton University In a twist on "survival of the fittest," researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride. These hitchhikers are mutations that do not appear to have a role in contributing to an organism's fitness and therefore its evolution, yet may play an important role down the road. Researchers from Princeton University...

Evolution Is Predictable Shown by Lizards
2013-07-19 10:21:14

University of California - Davis If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University and the University of Massachusetts. The work is published July 19 in the journal Science. The predictability of evolution over timescales of millions of years has long been debated by biologists, said Luke Mahler, a postdoctoral...

Antibiotic Overuse Could Lead To Serious Threat From Superbugs
2013-07-14 06:29:55

Michael Harper for redOrbit.com - Your Universe Online Australia's Office of Chief Scientists released a report on Friday that claims the misuse and overuse of antibiotics could soon send the world back to a nineteenth century era where typical diseases and infections could pose a serious threat. According to the report, many bacterium have become immune to the drugs that are often prescribed to treat those with ear infections, sore throats and more. These claims echo other recent...

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...
