With more than 1.2 million known living species and a fossil record extending back over 520 million years, arthropods have been megadiverse since animals radiated in the Cambrian explosion. The disparity between the main groups – insects, crustaceans, myriapods and chelicerates – has complicated efforts to resolve the evolutionary tree for Arthropoda, but modern molecular approaches, new ways of imaging anatomy, and the discovery of exceptionally preserved fossils are all contributing to a coherent picture.
Dr Greg Edgecombe from the Natural History Museum has been wrestling with how the major groups of arthropods relate to each other for some 20 years. This talk will travel from the Cambrian to the modern, arguing why insects are really crustaceans, molecules and morphology agree much more than they disagree, and will bring some ancient fossil brains into the mix.
This meeting is free and open to all; registration is not necessary.
Tea and coffee will be served in the Library from 17:30 and a wine reception will follow.
