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...

Beneficial Mutations have still not been found in the wild, though their existence was confidently predicted in the 1940s. Article published at http://www.takeondarwin.com asks, could they, like Unicorns, actually be mythical? ROSENDALE NY (PRWEB) February 06, 2013 Existence of the Beneficial Mutation was confidently predicted in the 1940s as part of the Modern Synthesis. In fact, if the Beneficial Mutation could be shown not to exist, the Modern Synthesis itself might be brought into...

Mutations which affect the gene ASXL3 cause a novel syndrome similar to Bohring-Opitz syndrome, finds a study published in BioMed Central's open access journal Genome Medicine. This molecular definition distinguishes these children from those with Bohring-Opitz, and other similar syndromes, and highlights a technique able to help define rare diseases. When Dr Ropers from the Max-Planck Institute for Molecular Genetics in Berlin found a child with non-specific symptoms, including small size...

Surprising result suggests that enhancing these mutations´ impact could offer a new way to treat cancer. A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression. But a new study from...

In the classic tradition of the dialogue, this one-hour play has Darwin and Galileo debating issues raised by us having evolved. It is intended to encourage humanities students to explore issues raised by evolution and come up with theories of their own. (PRWEB) January 30, 2013 Darwin and Galileo meet in heaven. On learning how Darwin won fame by coming up with evolutionary theory Galileo flies into a jealous rage and vows to win fame for himself by coming up his own theory of evolution....

Mollusks Could Be Responsible For Future Medications
2013-01-30 11:48:19

Brett Smith for redOrbit.com - Your Universe Online Two new mollusk-based studies from the Oregon Health & Science University show that new cutting-edge medications could be developed by simply looking to the sea. Because of accessibility issues, the ocean has always been a difficult place for identifying and utilizing the natural resources located there. Sadly, when many of these resources were tapped, they were done so in an unsustainable manner. The first study, which was...

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...
