Category: Time, Wasting of; Wastrels; Waste; Killing of. The Tree of Life website, which I stumbled across rather by accident but am sure is better known to the reading public, will suck away your afternoon.

Each page contains information about a particular group of organisms (e.g., echinoderms, tyrannosaurs, phlox flowers, cephalopods, club fungi, or the salamanderfish of Western Australia). 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.

That line about the "root of all Life on Earth" had me worried that they were rather overconfident; fortunately, the complexity of that question is honored:

The rooting of the Tree of Life, and the relationships of the major lineages, are controversial. The monophyly of Archaea is uncertain, and recent evidence for ancient lateral transfers of genes indicates that a highly complex model is needed to adequately represent the phylogenetic relationships among the major lineages of Life.

Cool.
