Searching for good sites

Google search hacks:
use quotation marks around phrases you specifically need to appear in results
if your search terms deliver results that make sense but aren't what you want, you can subtract what you don't want to see by using the hyphen. For example, you can search for equine evolution -racing to weed out all the information about horse racing and the evolution of the sport from your results.
ask Google to deliver certain web domains, such as .edu sites. Do this by entering your search phrase plus "site:" with whatever domain you want, such as .edu or .org. Like this: equine evolution site:edu

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.
