Release of TimeTree v2.0, with new data and many new features. The web site appearance was redesigned, with greater width and more options, including electronic resources for the newly published book The Timetree of Life. Divergence time data from 500 new studies were added to the 181 studies previously in TimeTree, bringing the database up-to-date. It now contains data from all organisms and MOST studies published up to the end of 2008. Please send PDFs or at least citations for any studies not included to submissions@timetree.org.
