In the course of their evolution domestic animals were selected by man not only for physical characteristics and physiological properties, but also for certain behaviour patterns. This permits us to trace the development of new behaviours during historically documented time. In three pigeon breeds — Swing Pouter, Birmingham Roller, Rhine Ringbeater — the development and evolution of breed-specific flight manoevers with courtship function under the influence of human selection was examined, and their course reconstructed. Behaviour patterns which in wild animals would have been eliminated through natural selection were able to develop under human protection and selection.
