CAUTION: These results are sensitive to both the classification (taxonomic names) and the "guide tree" used. For both, TimeTree uses NCBIs Taxonomy Browser, which will yield a reliable result in most cases. However, NCBI may not use the classification you believe to be correct, or that was used by a study being queried, in which case the time estimates presented here may be unusable. Other options will be available in the future. Until then, check the individual study results at the bottom of the page for proper taxonomy before using summary information. If in doubt, consult The Timetree of Life or original literature.

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.
