The evolution of novel characteristics within organisms can be enhanced when environments change in a systematic manner, according to a new study by Weizmann Institute researchers. Merav Parter, Nadav Kashtan and Uri Alon 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. Details are published November 7 in the open-access journal PLoS Computational Biology. http://www.physorg.com/news145251833.html Biology Fri, 07 Nov 2008 03:43:53 EST news145251833
