title: Data from: Cognitive capacities for cooking in chimpanzees

description: The transition to a cooked diet represents an important shift in human
 ecology and evolution. Cooking requires a set of sophisticated cognitive
 abilities, including causal reasoning, self-control and anticipatory
 planning. Do humans uniquely possess the cognitive capacities needed to
 cook food? We address whether one of humans' closest relatives,
 chimpanzees (Pan troglodytes), possess the domain-general cognitive skills
 needed to cook. Across nine studies, we show that chimpanzees: (i) prefer
 cooked foods; (ii) comprehend the transformation of raw food that occurs
 when cooking, and generalize this causal understanding to new contexts;
 (iii) will pay temporal costs to acquire cooked foods; (iv) are willing to
 actively give up possession of raw foods in order to transform them; and
 (v) can transport raw food as well as save their raw food in anticipation
 of future opportunities to cook. Together, our results indicate that
 several of the fundamental psychological abilities necessary to engage in
 cooking may have been shared with the last common ancestor of apes and
 humans, predating the control of fire.
