Description

TimeTree 4 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 4 contains data from 2,274 studies including 50,632 species. We will be adding more data in the future as it comes in from researchers.

TimeTree 4 requires iOS 8.0 or newer.

The TimeTree project is jointly directed by Blair Hedges (Center for Biodiversity, Temple University) and Sudhir Kumar (Institute for Genomics and Evolutionary Medicine, Temple 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.

Great educational tool

While the app is somewhat prone to crashing on occasion, it’s a great educational tool for showing how close or distant two organism’s common ancestor is. Despite not being a teacher or officially a biology major myself (yet), I’ve been able to use this app to teach friends about relations between organisms.

Of practical value to understand evolutionary relationships

Excellent source of information regarding taxonomic relationships and last-common ancestor (LCA). Useful for preparing lectures when I want to check on age of various species of birds, dinosaurs, etc. The online linkages to taxonomics at NCBI is very helpful.
Fun to check on LCA of different birds when out in the field, though some of the ages of LCA seemed surprising to me.
I hope that they will also provide a version that is designed for display on iPad2.
Would be helpful if they also listed the organism they suggest as the LCA.
Price is unbeatable (free!).

Crashes instantly

This app used to be great! I used it on an old iPad 2. I just attempted to use it on the iPad Pro 9" and it cannot even open: just crashes instantly. Please fix it so I can use it with teaching my life science classes...
