Beschreibung:
Modern humans are the only fully terrestrial ape. All other apes are
\npartially arboreal, particularly as infants and juveniles. Precocial locomotor
\ndevelopment, high frequency of arboreal locomotion in early ontogeny, and
\nincreased terrestriality throughout development are ubiquitous amongst the
\nhominines and likely represent the ancestral state. The role of climbing in
\nhominin evolution has been debated for decades, but if hominins climbed
\nregularly then subadults likely relied on it most frequently. Investigating the
\nrole of climbing throughout hominin evolution requires reliable developmentally
\nplastic traits that are responsive to locomotor loading and can be identified in the
\nfossil record. Chimpanzees and gorillas provide a natural experiment to examine
\nthe relationship between age-related variation locomotor activities and bone
\nstructure. Chimpanzees and gorillas are most arboreal during infancy and
\nbecome more terrestrial throughout development. Gorillas are comparatively
\nmore terrestrial and transition to predominantly terrestrial locomotion at an
\nearlier age. This paper has two main objectives. First, to examine if interspecific
\ndifferences in the rate of locomotor development is reflected in bone structure.
\nSecond, to determine if ontogenetic reductions in the frequency of arboreal
\nlocomotion correspond to age-related variation in bone structure.
