West Africa Chimps are Losing their Culture

In a recent research published, scientists with the Taï Chimpanzee Project in West Africa reported four dialects that male wild chimpanzees (Pan troglodytes verus) use in the Taï National Park to find mates to copulate with.

About Animal Culture Traditions

• Cultural Traditions have been found among animals in the way they forage, socialise, use tools, care for themselves, and mate.
  • Among these traditions, the characteristic patterns of behaviour that involve communication are called dialects.
• Studied Animals: There is evidence that whales, dolphins, elephants and primates acquire some of their knowledge and skills through social learning from adults or peers about various behaviours, including optimal migration routes.
  • Example: Cultural traditions in animals include variable socially transmitted behaviors such as the songs of humpback whales, prey preferences of orcas, and migratory routes of bighorn sheep
• Preservation of Animal Culture:
  • IUCN: It is a relatively new concept with The International Union for the Conservation of Nature (IUCN) recently including it among the metrics it uses to prepare its ‘Red List of Endangered Species’.
  • The Convention on the Conservation of Migratory Species of Wild Animals (CMS): Animal culture (the learning of non-human species through socially transmitted behaviours) is being linked to conservation action for the first time at CMS COP13.
• Importance: 
  • Adaptation: Animals with rich cultural repertoires are better equipped to innovate and adapt, using learned behaviors to exploit new resources or navigate new challenges
  • Repository of Practical Knowledge: The elders in a species possess important cultural knowledge which they pass on to their offsprings like, finding the best watering holes in particular weather, the ways to respond to different predators, caring for the young etc essential for survival.
    • A 2024 paper published in journal Science, has reported that the deaths of a species’ elders are disproportionately more harmful than the deaths of other members. 
  • Survival: Protecting cultural knowledge among peers and across generations may be vital for the survival and successful reproduction of certain species. 
  • To Conserve Critical Habitat: Supporting individuals that act as ‘repositories’ of social knowledge such as elephant matriarchs, or groups of knowledgeable elders, may be just as important as conserving critical habitat. 
    • Example: To understand how some Chimpanzees have a culture of cracking nutritious nuts with stone tools while others do not, can be key to evaluating conservation challenges for such species
  • Ecological Insurance: Cultural diversity acts as a form of ecological insurance, enabling populations to respond to unpredictable changes in their surroundings.
  • Species Understanding: To examine how cultural practices vary across species providing  a deeper understanding of the similarities and differences in social behaviors and cognitive abilities between species, including humans.
• Threats: 
• • Habitat Loss and Fragmentation: As animal habitats shrink and become fragmented, it becomes harder for animals to maintain their cultural traditions, which often depend on specific territories, resources, and social structures.
  • Human Influence: Anthropogenic activities like noise pollution, light pollution etc can disrupt animal communication, social interactions, and foraging behaviors and social fabric of these species posing severe impacts.
    • Example: The Southern Right Whales’ knowledge of migration routes around New Zealand’s coastline was lost to the species as a result of commercial whaling in the 1800s. 
  • Climate Change: It is altering ecosystems, leading to changes in resource availability, migration patterns, and predator-prey relationships, all of which can disrupt animal cultural traditions
