Lizards Facing Mass Extinction
2013-03-08 05:14:08

Alan McStravick for redOrbit.com - Your Universe Online One adage has held true throughout the whole of global history for every living organism on earth; When faced with a challenging situation, a species must either adapt or die. Researchers from the University of Exeter (UofE) and the University of Lincoln (UofL) believe they have discovered a dire situation for one specific species where its earlier adaptation will likely lead to its eventual death and ultimate extinction. In...

What do cancer cells, weeds, and pathogens have in common? They all evolve resistance to the treatments that are supposed to eliminate them. However, researchers developing the next generation of antibiotics, herbicides, and anti-cancer therapeutics rarely come together to explore the common evolutionary principles at work across their different biological systems. The new American Academy of Microbiology report "Moving Targets: Fighting Resistance in Infections, Pests, and Cancer" concludes...

Genome Police Undermined By Selfish Gene
2013-03-05 10:58:36

Brown University Biologists have been observing the “selfish” genetic entity segregation distorter (SD) in fruit flies for decades. Its story is a thriller among molecules, in which the SD gene destroys maturing sperm that have a rival chromosome. A new study reveals a tactic that gives SD´s villainy an extra edge. For a bunch of inanimate chemical compounds, the nucleic and amino acids caught up in the infamous “selfish” segregation distorter (SD) saga have...

Fossils Show Anatomy Of Ancient Fuxianhuiid Arthropod
2013-02-28 09:06:34

April Flowers for redOrbit.com - Your Universe Online An international group of scientists led by researchers at the University of Cambridge has made an extraordinary find in South China. For the first time, scientists are able to see through the head of the "fuxianhuiid" arthropod, revealing one of the earliest evolutionary examples of limbs used for feeding along with the oldest nervous system to stretch beyond the head in fossil record. Prior to this find, heads covered by a...

Evolution Of Bacteria Has Become Predictable
2013-02-20 19:24:20

Brett Smith for redOrbit.com — Your Universe Online The principles of evolution are widely accepted, but the causes and mechanisms that drive evolution are still heavily debated. In a new study published in the open access journal PLOS Biology, two researchers found similar or identical genetic mutations can emerge in separate populations of E. coli evolving in different environments for over 1000 generations, leading the team to conclude that evolution can be fairly...

Mutant Champions Save Vulnerable Species From Almost-certain Extinction
2013-02-20 12:52:16

University of Washington Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. Populations of disease-causing bacteria evolve, for example, as doctors flood their “environment,” the human body, with antibiotics. Insects, animals and plants can make evolutionary adaptations in response to pesticides, heavy metals and overfishing. Previous studies have shown that the more gradual the change, the better the...

A genetically mosaic Eucalyptus tree is able to control which leaves are saved from predation because of alterations in its genes, finds an study published in BioMed Central's open access journal BMC Plant Biology. Between two leaves of the same tree there can be many genetic differences — this study found ten SNP, including ones in genes that regulate terpene production, which influence whether or not a leaf is edible. Organisms collect somatic genetic mutations throughout their...

Men’s Superior Spatial Skills May Be Mere Chance
2013-02-20 08:38:12

Jedidiah Becker for redOrbit.com — Your Universe Online In recent decades, a plurality of studies have emerged confirming an age-old, cross-cultural gender stereotype with which we´re all familiar — namely, that the average man has (slightly) better spatial-navigational skills than the average woman. As study after study has buttressed what appears to be a case of natural chauvinism, the go-to explanation for the discrepancy has gone something like this: The males who...

Scientist Recommends Research Method Change For Evolutionary Biology
2013-02-16 08:11:00

April Flowers for redOrbit.com — Your Universe Online Shozo Yokoyama, a biologist at Emory University, says evolutionary biologists need to shift their focus from present-day molecules to synthesized, ancestral ones to truly understand the mechanisms of natural selection. Yokoyama presented evidence to support his claim at the American Academy of Arts and Sciences (AAAS) meeting in Boston this week. "This is not just an evolutionary biology problem, it's a science problem,"...

Genetic Variation Helped Humans Evolve, Adapt To Climate Changes
2013-02-15 10:05:03

[Watch Video: 2 Studies Reveal Genetic Variation That Drives Human Evolution] April Flowers for redOrbit.com - Your Universe Online New light has been shed on a genetic variation that may have played a key role in human evolution by two studies published by an international group of researchers this week in the journal Cell. To understand a gene variant that might have helped humans adapt to humid climates, the research team used an animal model, along with whole-genome sequencing...

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...

  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
