How does intraspecific variation appear in the sociality of chimpanzees?
In order to answer this question, LFE Director Daniel Haun, together with Edwin van Leeuwen and Katherine Cronin, designed a research project. Over a period of three years, they compared four chimpanzee populations in terms of social proximity and grooming tendencies. The aim was to investigate whether differences exist at population level that cannot be easily explained by genetic or environmental factors.
The article on the study has now been published in the journal PNAS, published by the National Academy of Sciences, as a title topic and can be read here .
