Brains And Other Modular Systems Prove Efficient For Artificial Intelligence
2013-01-30 13:25:07

Michael Harper for redOrbit.com — Your Universe Online As most of us know, scientists are deep thinkers. Finding the answers to “how” or “why” are not always enough for these brainiacs, who often spend as much time asking more questions as they do answering them. “Why does this work the way it does?” “How did this come into being?”: Questions like these are what drive scientists. And whatever the answer, there´s always another...

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...

Little Brown Bats Found To Have A Rare Active Jumping Gene
2013-01-04 07:37:34

April Flowers for redOrbit.com - Your Universe Online Jumping genes, or transposable elements, are strange rogue sequences from which most of our DNA can be traced, but are largely idle in mammals. Johns Hopkins researchers report, however, that they have identified a new DNA sequence moving around in bats. This is the first member of the transposable elements class found to be active in mammals. The findings of this study, published online at the Proceedings of the National Academy of...

In a comparison made between the actual progress of evolution and how it would have progressed if the mechanism had been genetic mutation and natural selection, the two progress in opposite directions. According to website http://www.takeondarwin.com, claims made for the Modern Synthesis are contradicted by what is known of the actual progress of evolution. ROSENDALE, NY (PRWEB) December 28, 2012 In Evolution Issue of the Month 8 published on the website http://www.takeondarwin.com...

The Evolution Of Grass Photosynthesis
2012-12-26 05:22:06

Brett Smith for redOrbit.com - Your Universe Online In examining the differences in photosynthetic activity among certain types of grasses, researchers from Brown University found that some plants are positioned to take evolutionary advantage of certain situations. According to a report in the Proceedings of the National Academy of Sciences, Brown researcher Pascal-Antoine Christin spent two years analyzing the cellular anatomy of 157 living species of two different grass clades, BEP...

Giant Panda Genome Sequencing Reveals Population History
2012-12-17 05:16:35

redOrbit Staff & Wire Reports - Your Universe Online By re-sequencing the genomes of nearly three dozen wild giant pandas, a team of Chinese scientists say that they have managed to construct a complete, continuous history of this rarest member of the bear family, from its origins to the current day. The researchers, who were led by the Institute of Zoology at the Chinese Academy of Sciences (CAS) and the genome sequencing center BGI, completed whole genome re-sequencing of 34...

How does evolution innovate? We exist because our ancestors have had the ability to adapt successfully to changes in their environment; however, merely examining present-day organisms can limit our understanding of the actual evolutionary processes because the crucial events have been masked by the passage of aeons — what we need is a time machine. Scientists from VIB, KU Leuven, University of Ghent and Harvard have done the next-best thing; by reconstructing DNA and proteins from...

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...
