as well as Buss, 2005; Durrant & Ellis, 2003; Pinker, 2002; Tooby & Cosmides, 2005) argue that much of human behavior is generated by psychological adaptations that evolved to solve recurrent problems in human ancestral environments. They hypothesize, for example, that humans have inherited special mental capacities for acquiring language, making it nearly automatic, while inheriting no capacity specifically for reading and writing.
