Data from: Coordination strategies of chimpanzees and human children in a stag hunt game

Shona Duguid, Emily Wyman, Anke F. Bullinger, Katharina Herfurth-Majstorovic & Michael Tomasello
Much of human cooperation takes place in mutualistic contexts in which the main challenge for individuals is how to coordinate decisions. In the current studies, we compared the abilities of chimpanzees and young children to coordinate with a partner in two versions of a Stag Hunt game. When risks were low (the hare was of low value) and information was cheap (the partner's behaviour was readily observable), partners of both species were able to successfully...

Data from: Chimpanzees trust conspecifics to engage in low-cost reciprocity

Jan M. Engelmann, Esther Herrmann & Michael Tomasello
Many of humans' most important social interactions rely on trust, including most notably among strangers. But little is known about the evolutionary roots of human trust. We presented chimpanzees (Pan troglodytes) with a modified version of the human trust game—trust in reciprocity—in which subjects could opt either to obtain a small but safe reward on their own or else to send a larger reward to a partner and trust her to reciprocate a part of...

Data from: Domestic dogs and puppies can use human voice direction referentially

Federico Rossano, Marie Nitzschner & Michael Tomasello
Domestic dogs are particularly skilled at using human visual signals to locate hidden food. This is, to our knowledge, the first series of studies that investigates the ability of dogs to use only auditory communicative acts to locate hidden food. In a first study, from behind a barrier, a human expressed excitement towards a baited box on either the right or left side, while sitting closer to the unbaited box. Dogs were successful in following...

Data from: Human children rely more on social information than chimpanzees

Edwin J. C. Van Leeuwen, Josep Call & Daniel B. M. Haun
Human societies are characterized by more cultural diversity than chimpanzee communities. However, it is currently unclear what mechanism might be driving this difference. Since reliance on social information is a pivotal characteristic of culture, we investigated individual and social information reliance in children and chimpanzees. We repeatedly presented subjects with a reward-retrieval task on which they had collected conflicting individual and social information of equal accuracy in counterbalanced order. While both species relied mostly on...

Data from: Efficient inference of recombination hot regions in bacterial genomes

Koji Yahara, Xavier Didelot, M Azim. Ansari, Samuel K. Sheppard & Daniel Falush
In eukaryotes, detailed surveys of recombination rates have shown variation at multiple genomic scales and the presence of “hotspots” of highly elevated recombination. In bacteria, studies of recombination rate variation are less developed, in part because there are few analysis methods that take into account the clonal context within which bacterial evolution occurs. Here we focus in particular on identifying “hot regions” of the genome where DNA is transferred frequently between isolates. We present a...

The severe Ebola virus disease epidemic occurring in West Africa stems from a single zoonotic transmission event to a 2-year-old boy in Meliandou, Guinea. We investigated the zoonotic origins of the epidemic using wildlife surveys, interviews, and molecular analyses of bat and environmental samples. We found no evidence for a concurrent outbreak in larger wildlife. Exposure to fruit bats is common in the region, but the index case may have been infected by playing in...
