Human Face Are So Variable Because We Evolved To Look Unique

Robert Sanders, University of California - Berkeley The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a...

Robert Perkins, University of Southern California New study turns a long-accepted evolutionary assumption on its head, finding that whale pelvic bones play a key role in mating Both whales and dolphins have pelvic (hip) bones, evolutionary remnants from when their ancestors walked on land more than 40 million years ago. Common wisdom has long held that those bones are simply vestigial, slowly withering away like tailbones on humans. New research from USC and the Natural History...

Saurabh Thosar, Indiana University An Indiana University study has found that three easy -- one could even say slow -- five-minute walks can reverse harm caused to leg arteries during three hours of prolonged sitting. Sitting for long periods of time, like many people do daily at their jobs, is associated with risk factors such as higher cholesterol levels and greater waist circumference that can lead to cardiovascular and metabolic disease. When people sit, slack muscles do not...

David Orenstein, Brown University The gravity of the world’s current extinction rate becomes clearer upon knowing what it was before people came along. A new estimate finds that species die off as much as 1,000 times more frequently nowadays than they used to. That’s 10 times worse than the old estimate of 100 times. It’s hard to comprehend how bad the current rate of species extinction around the world has become without knowing what it was before people came along. The newest...

David Gilbert, DOE/Joint Genome Institute One aspect of the climate change models researchers have been developing looks at how plant ranges might shift, and how factors such as temperature, water availability, and light levels might come into play. Forests creeping steadily north and becoming established in the thawing Arctic is just one of the predicted effects of rising global temperatures. A recent study published online August 24, 2014 in Nature Genetics offers a more in-depth,...

Peter Iglinski, University of Rochester A newly-discovered species of ant supports a controversial theory of species formation. The ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development. “Most new species come about in geographic isolation,” said Christian Rabeling, assistant professor of...

redOrbit Staff & Wire Reports - Your Universe Online Honeybees are more genetically diverse than originally thought, and the species might have originated from Asia and not Africa as previously believed, according to new research published online Sunday in the journal Nature Genetics. As part of their study, researchers from the Uppsala University Department of Medical Biochemistry and Microbiology and an international team of colleagues present the first global analysis of genome...

A'ndrea Elyse Messer, Penn State The small body size associated with the pygmy phenotype is probably a selective adaptation for rainforest hunter-gatherers, according to an international team of researchers, but all African pygmy phenotypes do not have the same genetic underpinning, suggesting a more recent adaptation than previously thought. "I'm interested in how rainforest hunter-gatherers have adapted to their very challenging environments," said George H. Perry, assistant professor...

Iqbal Pittalwala, University of California, Riverside UC Riverside-led research could revolutionize hybrid breeding in agriculture Genomic prediction, a new field of quantitative genetics, is a statistical approach to predicting the value of an economically important trait in a plant, such as yield or disease resistance. The method works if the trait is heritable, as many traits tend to be, and can be performed early in the life cycle of the plant, helping reduce costs. Now a...

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...
