Time Tree

TimeTree is a public knowledge-base for information on the evolutionary timescale of life. A search utility allows exploration of the thousands of divergence times among organisms in the published literature. A tree-based (hierarchical) system is used to identify all published molecular time estimates bearing on the divergence of two chosen taxa, such as species, compute summary statistics, and present the results . . . For those interested in published summaries of relationships and divergence times of major groups of organisms (family level and above), see the authoritative synthesis The Timetree of Life.

Here are some examples to get you started: Humans and Chimpanzees diverged 6.3 MYA; Giraffes and Dolphins diverged 58.3 MYA; Cats and Mice diverged 95.2 MYA; and Dogs and Fleas diverged 777.8 MYA. [more inside]

Let me show you a world of bats and bees, ants and trees, morning glories and a few beached whales

The Graduate University for Advanced Studies, casually referred to as Sōkendai (a contraction of Sōgō kenkyū daigakuin daigaku), was founded in 1988 as the 96th national university in Japan. Amongst other things, it is home to the Soken Taxa Web Server which in turn hosts the first online Japanese Ant Color Image Database that currently lists 273 species of ant, the Illustrated Guide of Marine Mammals and the Marine Mammals Stranding DataBase, the Mammalian Crania Photographic Archive that currently includes 704 specimens, the Morning Glories Database that covers the many mutants of Ipomoea nil, closely related species and interspecific hybrids, the Makino Herbarium Database, which is named after the pioneering Japanese botanist, Tomitaro Makino, and the Japanese Bees Image Database.
