TimeTree of Life

TimeTree is a public knowledge-base for information on the evolutionary timescale of life. Data from thousands of published studies are assembled into a searchable tree of life scaled to time. Three search modes are possible:

  • Node Time - to find the divergence time of two species or higher taxa
  • Timeline - to drill back through time and find evolutionary branches from the perspective of a single species
  • Timetree - to build a timetree of a group of species or custom list

Timepanels showing events in geological time and astronomical history are provided for comparison with timelines and timetrees. Results can be exported in different formats for additional analyses and publication.
