Animal Culture: Chimpanzee Conformity?
Culture-like phenomena in wild animals have received much attention, but how good is the evidence and how similar are they to human culture? New data on chimpanzees suggest their culture may even have an element of conformity.

(Figure 1A,B). These results illustrate that DCC distribution is dynamically specified by developmental changes in gene expression. The aspect of transcriptional activity recognized by the DCC is unknown. Possibilities include chromatin features (e.g., nucleosome-free regions or variants and modifications of histones), or the transcription machinery itself. One suspect is histone H3 K4 methylat...
متن کاملThe knowns and unknowns of chimpanzee culture.
Claims of culture in chimpanzees appeared soon after the launch of the first field studies in africa.1 The notion of chimpanzee 'material cultures' was coined,2 and this was followed by a first formal comparison, which revealed an astonishing degree of behavioural diversity between the different study communities, mainly in terms of tool use.3 Although this behavioural diversity is still undisp...

High-arm grooming is a form of chimpanzee grooming in which two individuals mutually groom while each raising one arm. Palm-to-palm clasping (PPC) is a distinct style of high-arm grooming in which the grooming partners clasp each other's raised palms. In wild communities, samples of at least 100 observed dyads grooming with raised hands showed PPC frequencies varying from <5% (M group, Mahale) ...
متن کاملScalar properties in animal timing: conformity and violations.
The article reviews data from animal subjects on a range of timing tasks (including fixed-interval and temporal differentiation schedules, stimulus timing, aversive conditioning, and Pavlovian methods) with respect to conformity to the two scalar properties of timing behaviour: mean accuracy and scalar (Weberian) variance. Systematic deviations were found in data from temporal differentiation s...
