Up-to-date review of animals before the Cambrian ‘Explosion’

Since I began this blog in 2000 one of my most regular topics concerns the animals of the latest Precambrian: the Ediacaran fauna. If you want to browse through the items use ‘Ediacaran’ in the Search Earth-logs box. New material and ideas about those precursors to modern life forms (and some that are still puzzling) appear on a regular basis. Science journalist Traci Watson has just summarised the latest developments in an essay for Nature. It is a nicely written and copiously illustrated piece with lots of links. Rather than precis her article, I suggest that you go straight to it, if the topic piques your interest.
