"The appearance of wings is one the most spectacular novelties in insect evolution. The oldest unequivocal fossils of winged insects (Pterygota) are ca. 320 million years old. Nevertheless, the origin of insect wings is not still resolved. Even extensive investigations on the extant Pterygota have not been able to answer basic questions on the sequence of events, especially during the early time of insect flight evolution. To gain a better understanding of the processes during the evolution, we will study Palaeozoic fossils that show important parts of the flight apparatus beyond the wing venation, like the often complex wing joint and the thorax. We will investigate specimens with microscopy, high resolution X-ray tomography, 3D-surface scanning and scanning electron microscopy. The comparative analysis of the acquired data, together with information on extant pterygotes, will serve for the flight apparatus reconstruction. This will substantially extend our knowledge on the evolution of the insects, the group that by far comprises the largest number of species among all organisms."@en . . "2014-03-14+01:00"^^ . .
