Document Summary
What is it, why is it interesting to biology. What is the context in relation to the study of animal behaviour. Article 1 - sexual dimorphism and courtship behaviour in drosophila. In drosophila prolongata of the melanogaster species group. Used in specific behaviour of leg vibration, vigorously vibrate on female abdomen. Study of courtship of d prolongata in comparison with closely related species. Leg vibration not observed in closely related species. Sexual dimorphism of dp is under influence of sexual selection in courtship behaviour. Sexually dimorphic structures often accompanied by evolution of specific behaviour. Other species have their own sexual dimorphic things eg broad head, wing pigmentation, wing spots. Observe how sexually dimorphic structures are used in behavioural context to understand the evolution of that structure was selected for. Three species, dp, d rhophaloa, and d kurseongensis, and some other one kb866. D elegans, d takahasii, d melanogaster, d kikkawai outgroup for phylogenetic tree.
