Biology, culture, evolution and the cognitive nature of sound systems

The paper reviews a number of studies that take the evolutionary perspective, focusing notably on agent-based computer simulations and on experimental work that simulates evolution in the laboratory or experimental work that investigates the interaction between individual learning behavior and cultural transmission directly. The paper argues that taking the evolutionary perspective (both cultural and biological, as well as their interaction) into account is necessary for a full understanding of the cognitive nature of language and speech.
