It commands a signaling network more elaborate and diverse than found in any multicellular organism higher up on the evolutionary tree, researchers at the Salk Institute for Biological Studies have discovered.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/329846669" height="1" width="1" /></p> http://science-nature.marc8.com/can-you-hear-me-now-primitive-single-celled-microbe-expert-c#comments Top stories cellular communication evolutionary tree microbe multicellular organism salk institute for biological studies http://science-nature.marc8.com/crss/node/5841 Tue, 08 Jul 2008 10:45:07 -0500 admin 5841 at http://science-nature.marc8.com http://science-nature.marc8.com/when-plants-think-alike <p>(National Science Foundation) Biologists have discovered that a fundamental building block in the cells of flowering plants evolved independently, yet almost identically, on a separate branch of the evolutionary tree -- in an ancient plant group called lycophytes that originated at least 420 million years ago.</p> http://science-nature.marc8.com/when-plants-think-alike#comments Top stories biologists evolutionary tree flowering plants national science foundation plant group http://science-nature.marc8.com/crss/node/4901 Tue, 27 May 2008 00:00:00 -0500 admin 4901 at http://science-nature.marc8.com
