Evolution-Hominid Key Links: Kentucky Geological Survey's annotated links to the best web sites for understanding hominid (and human) evolution
Tree of Life Project. The project is a collaborative effort of biologists from around the world, which provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history. Click on a kingdom and follow the systematics (family tree) through the tree of life to more specific organisms. The tree uses technical (latin) names in a hierarchial classification (using cladistics/cladograms), but there is a general summary in an introduction along each part of the tree (scroll to text below the tree), followed by more technical information on characteristics, fossils, phylogenetic relationships, and references.
