A project involving Arizona State University's Institute for Human Origins (founded and directed by Donald C. Johanson, best-known for his discovery of "Lucy"), documentary filmmaker Lenora C. Johanson, and Terra Incognita, this site is designed to teach a general audience about human evolution and the search for early hominid life in the field. The key feature of the site is an extensive (and very professional) flash-driven, online documentary which includes a number of pop-up sub-exhibits that provide additional information and resources on various topics. Other sections of the site include News & Views, which offers recent paleo news stories and expert views, and Resources, which includes a glossary, related sites, and media references. A Learning Center with activities and lesson plans is scheduled to be added this summer. This site, probably the best online documentary seen by this reviewer, should appeal to anyone with an interest in human origins and is highly recommended.
