Earth Picking apart photosynthesis Posted On: March 29, 2013 - 1:00pm PASADENA, Calif.—Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory believe they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe.
The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world . On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history ( phylogeny ). Each page contains information about a particular group, e.g., salamanders , segmented worms , phlox flowers , tyrannosaurs , euglenids , Heliconius butterflies , club fungi , or the vampire squid . ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things. read more about the Tree of Life Web Project...
