How Evolution Learns From Past Environments To Adapt To New Envi...

The evolution of novel characteristics within organisms can be enhanced when environments change in a systematic manner, according to a new study. Researchers suggest that in environments that vary over time in a non-random way, evolution can learn the rules of the environment and develop organisms that can readily generate novel useful traits with only a few mutations.

Natural Selection May Not Produce The Best Organisms

"Survival of the fittest" is the catch phrase of evolution by natural selection. While natural selection favors the most fit organisms around, evolutionary biologists have long wondered whether this leads to the best possible organisms in the long run. A team of researchers has developed a new theory, which suggests that life may not always be optimal.

New observations from NASA's Mars Reconnaissance Orbiter indicate that the crust and upper mantle of Mars are stiffer and colder than previously thought. The findings suggest any liquid water that might exist below the planet's surface and any possible organisms living in that water, would be located deeper than scientists had suspected.

Study questions 'cost of complexity' in evolution

Higher organisms do not have a "cost of complexity" -- or slowdown in the evolution of complex traits -- according to a report by researchers at Yale and Washington University in Nature.
