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...

Determining Sexual Selection In Extinct Species
2013-01-30 08:11:48

Brett Smith for redOrbit.com - Your Universe Online According to a new study in the journal Trends in Ecology and Evolution, determining if certain extinct animals had sexually selective traits is possible, despite the fact that we cannot observe their behavior. Many animals have sexually selective traits that are used or displayed in pursuit of a mate, male peacocks have their colorful plumage and mallard ducks have a distinct green coloration to their head feathers. Some of these...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

Snapshot Of Pupfish Evolution In Action
2013-01-10 15:28:17

University of California - Davis Chris Martin has bred more than 3,000 hybrid fish in his time as a graduate student in evolution and ecology at UC Davis, a pursuit that has helped him create one of the most comprehensive snapshots of natural selection in the wild and demonstrated a key prediction in evolutionary biology. "We can see a surprisingly complex snapshot of natural selection driving the evolution of new specialized species," said Martin, who with Professor Peter Wainwright...

Slime Mold Gets Upper Hand By Cheating
2013-01-09 13:38:37

BioMed Central A 'cheater' mutation (chtB) in Dictyostelium discoideum, a free living slime mold able to co-operate as social organism when food is scarce, allows the cheater strain to exploit its social partner, finds a new study published in BioMed Central's open access journal BMC Evolutionary Biology. The mutation ensures that when mixed with 'normal' Dictyostelium more than the fair share of cheaters become spores, dispersing to a new environment, and avoiding dying as stalk cells....

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...
