Lee Rannals for redOrbit.com - Your Universe Online Research has revealed just what is behind a birds' song, shedding more light on nature's melody. Canadian researchers found that closely related birds that share the same habitat are not necessarily birds of the same feather that flock together in music, but instead tend to look and sound different. The team studied 250 bird species throughout the world and were able to compile a database of where the birds lived, and what they...

Two Fused Species Give Rise To Plant Pest

A fungal species native to Iran which attacks grasses is the result of natural hybridisation that occurred just a few hundred years ago Zymoseptoria tritici is often a headache for European farmers. This ascomycete originating from the Middle East attacks the leaves of wheat plants triggering "speckled leaf blotch", which can cut crop yields by up to 50 percent. Scientists from the Max Planck Institute for Terrestrial Microbiology in Marburg and Aarhus University in Denmark have now taken...

Frequency-dependent selection fosters the diversity of populations but does not always increase the average fitness of the population. Genetic diversity arises through the interplay of mutation, selection and genetic drift. In most scientific models, mutants have a fitness value which remains constant throughout. Based on this value, they compete with other types in the population and either die out or become established. However, evolutionary game theory considers constant fitness values...

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...

Pinta Island’s Lonesome George Passes Away
2012-06-25 10:21:34

Brett Smith for redOrbit.com Sadly, the sudden death of the giant tortoise Lonesome George on the Galapagos Islands this Sunday marks the loss of another subspecies from the face of the Earth. When scientists first met Lonesome George on Pinta Island in 1972, they had thought his species, Geochelone nigra abingdoni, was already extinct. He was immediately placed into the park service´s tortoise breeding program on Santa Cruz Island and while he did mate with a female tortoise...

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...

Connie K. Ho for redOrbit.com With food items like cheese and wine, it´s thought that a longer time of preparation will give it a better taste. This idea of age affecting quality was highlighted in a new study by Northwestern University scientists. A recent study by researchers at Northwestern University found that people whose fathers and grandfathers waited until they were older to have children tended to have a higher amount of resources for the body to repair cells and tissues....

Assembling, Visualizing And Analyzing A Tree Of All Life

National Science Foundation grants will bring together what's known about how species are related A new initiative aims to build a comprehensive tree of life that brings together everything scientists know about how all species are related, from the tiniest bacteria to the tallest tree. Researchers are working to provide the infrastructure and computational tools to enable automatic updating of the tree of life, as well as develop the analytical and visualization tools to study it....

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...

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...
