Sex crazed, but not too picky

Nature constantly engineers new and creative solutions to all sorts of problems—turning our stereotypes about sex upside-down along the way.

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]

Young Indiana Jones Discovers Missing Link (maybe....)

"So I called my dad over and about five metres away he started swearing, and I was like 'what did I do wrong?' and he's like, 'nothing, nothing - you found a hominid'."
The remarkable remains of two ancient human-like creatures (hominids) have been found in South Africa. Some researchers dispute that the fossils are of an unknown human species, but others say they may help fill a key gap in the fossil record of human evolution. [more inside]

What Is A Species? "To this day, scientists struggle with that question. A better definition can influence which animals make the endangered list."
