How It Works

Two species or higher taxa are queried (e.g., cat and dog).

TimeTree compares all taxa in one inclusive group (e.g., Feliformia) with those in the other group (e.g., Caniformia) to find all published times of divergence for the evolutionary split.

Downloads

On our Results page, you can download all individual time estimates and study data associated with the query. The iPhone and iPad apps, and all chapters of the Timetree of Life book, can be downloaded by using their respective links. In addition, we will soon make available a facility to download timetrees consisting of multiple species, where users will also be able to input their own species trees. These facilities will be available for a large number of species (>50,000 species) as soon as we complete the processing and synthesis of results from over 2000 studies into this resource. In the meantime, we provide the 1610-family timetree of life as a download here.
