Skype for the Classroom

Skype is developing a free online directory to make it easy for teachers to connect with other teachers and resources from around the world. The directory will launch in December 2010 in English only. Once you sign up with your Skype account and create a profile, you'll be able to search for other teachers and classes by subject and region. You can also share inspiration and tips to help students learn with Skype. The beta version is available for investigation now at the Skype pre-registration site.

Timetree of Life

The Timetree of Life contains electronic files of articles and figures from the book The Timetree of Life (2009), Oxford University Press, and a wall poster. These resources are copyrighted but are provided free for personal, research, or educational use.

TimeTree is a public knowledge-base for information on the evolutionary timescale of life. A search utility allows exploration of the thousands of divergence times among organisms in the published literature. A tree-based (hierarchical) system is used to identify all published molecular time estimates bearing on the divergence of two chosen taxa, such as species, compute summary statistics, and present the results. Check out the "resources" section, too, for links to other sites that focus on evolutionary history.
