Promiscuous Female Fruit Flies Prevent Male Extinction
2014-04-02 17:14:08

University of Liverpool Female fruit flies with a large number of sexual partners are playing an invaluable role in preventing the extinction of males, research at the University of Liverpool has shown. Scientists have found that flies in the northern parts of the United States are more inclined to have multiple partners in order to reduce the occurrence of an X chromosome which causes the production of only female offspring. This selfish genetic element (SGE) tries to replicate...

Scientists Identify Factors Limiting Hybridization Of Closely-related Woodrat Species
2014-03-31 08:41:24

Wildlife Conservation Society A pair of new studies from the Wildlife Conservation Society, Idaho State University, and the University of Nevada Reno look at the surprising variety of factors that prevent two closely related species of woodrats from becoming a single hybrid species despite the existence of hybrid individuals where the two species come into contact. After finding that two closely related species, the desert and Bryant's woodrats, could interbreed and produce hybrid...

Amphibians, Dinosaurs Were The New Large Predators After The Mass Extinction
2014-03-20 12:37:13

University of Zurich 252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear. A Swiss-American team of palaeontologists headed by Torsten Scheyer and Carlo Romano from the...

Sea Anemone genetics
2014-03-18 13:58:44

Lee Rannals for redOrbit.com - Your Universe Online Researchers lead by evolutionary and developmental biologist Ulrich Technau at the University of Vienna say that a sea anemone has a genomic landscape that is half animal, half plant. Developmental biologists found that the genetic landscape of sea anemones features complex regulatory elements similar to that of fruit flies or other animal model systems. However, they also discovered that sea anemones are more similar to plants rather...

Europeans' Appearance Altered Over Five Millennia Of Natural Selection

April Flowers for redOrbit.com - Your Universe Online A great deal of research has been focused on the factors that have influenced the human genome since the end of the last Ice Age. An international team of scientists—including anthropologists at Johannes Gutenberg University Mainz (JGU), geneticists at University College London (UCL), and archaeologists from Berlin and Kiev—has analyzed ancient DNA from skeletons, finding that natural selection has had a major effect on the human...

New Study Sheds Light On Animal Social Behavior
2014-03-06 15:04:31

University of Exeter A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations. Understanding the way in which social behaviors such as altruism – when animals benefit others at their own expense – develop is a long-standing problem that has generated thousands of articles and heated debates. Dr Florence Débarre of Biosciences at the University of Exeter led a study,...

Genome Analysis Reveals Origins Of Genetic Adaptations For High Altitude In Tibetans
2014-02-11 09:00:22

University of Chicago Medical Center Genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa. These genes were passed on to more recent migrants from lower elevations via population mixing, and then amplified by natural selection in the modern Tibetan gene pool, according to a new study by scientists from the University of Chicago and Case Western Reserve University,...

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...
