The lecture will be preceded by a short presentation by Jan Mertens on new materials

Dragonflies are among the most skilful and spectacular of all flying insects, and are also among the earliest to appear in the fossil record. Superficial resemblences between Palaeozoic fossils and modern forms make them favourites for creationists wishing to demonstrate that evolution is a myth. On the contrary detailed examination of the mechanics of their wings and the adaptive significance of changes in their structure through time provides excellent evidence of 300 million years of progressive refinement and improvement on a broad front, probably reflecting increasing flight agility in the prey on which they depend.
