If variations in memory capacities have been observed among closely-related species, the relationship between environmental conditions and evolution of these capacities have only been rarely studied despite the importance of this topic in the understanding of the evolution of behavior. Memory has long been considered as a unique and continuous process of information storage and degradation. However, recent studies have shown that this process could be divided in different distinct phases separated in time and in their functional mechanism. To have a better comprehension of the evolutionary biology of cognitive abilities, it is therefore important to understand the different natural selection pressures favoring one or another memory phase, the fitness related costs of these different memory phases and the constraints on their evolution. The approach I took is based on studying the direct and correlated responses in selection experiments, using fruit flies (Drosophila) as a model system. It allows one to observe the evolutionary process directly while controlling for confounding factors.
