Description

TimeTree is a public knowledge-base for information on the evolutionary timescale of life. This application allows easy exploration of the thousands of divergence times among organisms in the scientific literature. A tree-based (hierarchical) system is used to identify all published molecular time estimates bearing on the divergence of two chosen organisms, such as species, compute summary statistics, and present the results. Names of two taxa to be compared are entered in the search window and the results are presented on a set of self-explanatory tabs.

TimeTree 3.0 was released September 27, 2011 with new data from 1209 studies including 25342 time nodes. We will be adding more data in the future as it comes in from researchers.

TimeTree is jointly directed by Blair Hedges (Pennsylvania State University) and Sudhir Kumar (Arizona State University). This project has been supported, in part, by grants from the National Science Foundation, National Institutes of Health, NASA Astrobiology Institute, and Science Foundation of Arizona.

What's New in Version 3.1

Calculations have been improved so that the times from any one study do not dominate the overall results.

wonderful app that reaches further and further with citations and data. Comes from a world renown evolution genetics program. All I can say is thanks

Great!

Functions without issue. Data are accurate with references linked to NCBI summaries. Great reference and useful for illustrating evolutionary relationships in class. Bravo!

Awesome

This app is so great! Will be using for school and citing in papers. Links follow you to NCBI web page and the original study. Wow! Recommend.
