![]() Numerous studies have examined the different clasping styles of E African communities - a GHC clasp contains two arms which provide a functional shape through angles at the elbow and wrist joints, this is accompanied by specific connection points where the arms meet collectively we can refer to these elements as style.įor my study I investigated potential causes of intra-group variation responsible for the inter- community differences already identified in the literature. It has been proposed to be a signal of rank within the group, strengthening the hierarchical backbone of chimpanzee communities. Primarily, the GHC serves a grooming function, allowing both individuals access to certain portions of the partner’s body. The GHC differs between closely located groups and variation in the behaviour is not based on genetic or ecological differences (broadly speaking). The behaviour occurs across eastern, central, and western chimpanzee populations. The area is home to numerous mammal and bird species, and if fortunate – as I was – there is a chance to observe these species in their wild synchrony… more on this later.īut first, what is a GHC? It is best described as a social custom that is expressed between adult members of the community, individuals engage in a connection of arms overhead whilst they simultaneously groom one and other. I travelled to the GMERC research station in the Issa Valley during the latter part of 2021 to collect data on the Grooming Hand Clasp (GHC) in chimpanzees – but saw so much more! My time at Issa didn’t just reward me with chimpanzee observations. ![]() Habari! My name is Sam Baker, I’m a postgraduate from University College London in Bioanthropology. ![]()
