Jedidiah Becker for redOrbit.com — Your Universe Online Take a glance at the arc of human civilization. As just a few notable achievements, you might start with the discovery of agriculture before moving on to survey the architectural marvels of the ancient world, the revolution of Gutenberg´s printing press and finally landing on the modern ubiquity of rapidly evolving computer technology. This view tends to give a sense that the human intellect may have a nearly limitless...

Like job-seekers searching for a new position, living things sometimes have to pick up a new skill if they are going to succeed. Researchers from the University of California, Davis, and Uppsala University, Sweden, have shown for the first time how living organisms do this. The observation, published Oct. 19 in the journal Science, closes an important gap in the theory of natural selection. Scientists have long wondered how living things evolve new functions from a limited set of genes....

Where´s the white hot furnace that powers evolution? For Darwin it lay in natural selection. The “Modern Synthesis” relocated it to genetic mutation. In the third of a series of articles published at http://www.takeondarwin.com, Contrarian Evolutionist author Shaun Johnston relocates it once again, to wherever variations in living creatures are created. (PRWEB) July 16, 2012 Modern evolutionary theory is the opposite of what people assumed when they first wondered what made...

A classic study from more than 60 years ago suggesting that males are more promiscuous and females more choosy in selecting mates may, in fact, be wrong, say life scientists who are the first to repeat the historic experiment using the same methods as the original. In 1948, English geneticist Angus John Bateman published a study showing that male fruit flies gain an evolutionary advantage from having multiple mates, while their female counterparts do not. Bateman's conclusions have...

However, principles of natural selection may also hold key to thwarting emergence of drug resistance According to researchers at Moffitt Cancer Center, cancer is subject to the evolutionary processes laid out by Charles Darwin in his concept of natural selection. Natural selection was the process identified by Darwin by which nature selects certain physical attributes, or phenotypes, to pass on to offspring to better "fit" the organism to the environment. As applied to cancer, natural...

Natural selection was never a good idea, according to Contrarian Evolutionist author Shaun Johnston in the second of a series of articles published at http://www.takeondarwin.com. Natural selection couldn't account for where species or variation came from; no wonder Darwin hesitated to publish it. Even now when it's combined with genetic mutation natural selection is still not a good idea, Johnston claims. Rosendale, NY (PRWEB) June 16, 2012 There isn't much for Darwin to be very famous...

Darwin made adaptation to the environment the key property of evolved living creatures. That's all natural selection can do. But suppose the key property of living creatures is how independent of their environment they are. This is number 1 in a series of website articles casting doubt on the Modern Synthesis. Rosendale, NY (PRWEB) May 29, 2012 In Darwin's theory of natural selection the key concept is "adaptation to the environment." All natural selection could do was identify which...

UCLA-Tel Aviv University team models genetic variation in 2-D, 3-D space Understanding the genetic diversity within and between populations has important implications for studies of human disease and evolution. This includes identifying associations between genetic variants and disease, detecting genomic regions that have undergone positive selection and highlighting interesting aspects of human population history. Now, a team of researchers from the UCLA Henry Samueli School of...

Max Planck scientists decode genes for a complex characteristic Organisms are adapted to their environment through their individual characteristics, like body size and body weight. Such complex traits are usually controlled by many genes. As a result, individuals show tremendous variations and can also show subtle gradations. Researchers from the Max Planck Institute for Evolutionary Biology in Plön have now investigated how evolution alters such traits through selection. To...

Darwinian Selection Continues To Influence Human Evolution

New evidence proves humans are continuing to evolve and that significant natural and sexual selection is still taking place in our species in the modern world. Despite advancements in medicine and technology, as well as an increased prevalence of monogamy, research reveals humans are continuing to evolve just like other species. Scientists in an international collaboration, which includes the University of Sheffield, analyzed church records of about 6,000 Finnish people born between...
