The aquatic ape theory or aquatic ape hypothesis (AAT/AAH) is a hypothesis in evolutionary biology proposing that the ancestors of human ancestors went through one or more periods of time living in a semi-aquatic setting and that this accounts for many of the characteristics of species in the Homo genus that are not seen in other primates, such as chimpanzees or gorillas.
Most orthodox paleoanthropologists adhere to the Savanna Theory, which holds that human ancestors evolved in hot and dry savanna environments.
The aquatic ape theory says that human ancestors evolved in warm and wet environments and went through one or more periods of time living in a waterside setting, gathering much of their foods from shallow sea-, lake- or riverside environments through beach-combing, wading and diving, for instance, coconuts, bird's eggs, turtles, shell- and crayfish, part of reeds, papyrus and other aquatic plants. There are interpretations which propose fresh-water habitats (Ellis 1993), variations in the timescale (Verhaegen et al. 2002) and the proposed degree of selection arising from moving through water. One interpretation is that the semi-aquatic episode coincided with the Pliocene-Pleistocene littoral diaspora of Homo along the East-African Rift valley lakes and the African and Indian Ocean coasts.
