Cultural variety and the origin of human thinking

How did our evolutionary ancestors make sense of their world? What strategies did they use, for example, to find food? Fossils do not preserve thoughts. Therefore, an cross-institutional research group at the Max Planck Institutes for Psycholinguistics and Evolutionary Anthropology use an alternative research method: comparative psychological research. In this way, they discovered that some of the strategies shaped by evolution are evidently masked early on by the cognitive development process unique to humans.
