Zusammenfassung
Tool use occurs in several non-human species, including
primates. Within the genus Pan, chimpanzees (P. troglodytes)
exhibit tool use in both the wild and captivity, while tool use in
bonobos (P. pansiscus) has been documented in captivity and
suggested to occur in the wild (White et al. 2008). Four
conditions have been proposed to facilitate the evolution of
material culture: 1) ecological opportunity, 2) motor dexterity, 3)
cognition for problem solving and 4) social tolerance to allow for
social learning of tool use behavior (van Schaik et al. 1999).
Social tolerance behavior varies among the great apes and a
recent captive study showed that bonobos had fewer neighbors
present during tool use acquisition than what has been reported
for chimpanzees and gorillas (Boose et al 2013, Lonsdorf et al.
2009). These captive bonobos also exhibited a female bias in
tool use acquisition that has been well documented in Pan
(Boose et al. 2013, see also Gruber et al. 2010). We sought to
investigate patterns of affiliation and association during tool use
within this captive group of bonobos by analyzing sex and age
differences. Based on what has been reported for bonobos
regarding their affiliative patterns, we predicted females would
be more social than males.
