Visitors can learn how the collaboration, consisting of one-thousand members from twenty-seven countri
Human Evolution
The first Web site is an article from the New York Times (1) detailing some recent fossil discoveries that are shaking the paleontological world (free registration is required). Another relatively recent article from Guardian Unlimited (2) discusses a scientific debate surrounding the question of whether "a Western lifestyle now protects humanity from the forces that used to shape Homo sapiens." The third resource (3) includes a likely timeline of events in the history of hominids and a tour of
Human Identification at a Distance
The Georgia Institute of Technology is conducting research on Human Identification at a Distance, with an emphasis on gait recognition. Supported by the Defense Advanced Research Projects Agency (DARPA), the project's development of gait recognition systems and algorithms is "an example of an activity-specific biometric: a method of extracting some identifying properties of an individual or of an individual's behavior that is only applicable when a person is performing that specific action." Sev
Deep Content: Guide to Effective Searching of the Internet
This outstanding website is, without question, one of the most comprehensive online resources for learning efficient Internet search techniques. The guide begins with some fairly non-technical background about the Internet and explains why searching such a massive amount of information is more complex than it seems. The general process used by search engines to rank webpages is described. After covering the fundamentals of search engine operation, the guide discusses some best practices to use w
Quaternary Studies
First, the Irish Quaternary Association (IQUA) website publicizes its aim "to promote Quaternary studies in Ireland through its publications, and the organization of field meetings and conferences" (1).
