متن کاملKinematics of bipedal locomotion while carrying a load in the arms in bearded capuchin monkeys (Sapajus libidinosus).
Understanding the selective pressures that drove the evolution of bipedalism in the human lineage may help inform researchers about the locomotor mode(s) of pre-hominin ancestors. Several selective pressures have been hypothesized, including the need to carry food, tools, or infants. Bearded capuchin monkeys are an excellent primate in which to examine the hypothesis that carrying supported the...
متن کاملWild Bearded Capuchin Monkeys Crack Nuts Dexterously
Dexterous tool use has been crucial in the evolution of hominid percussive technology. According to Newell, "dexterity" is the ability of an organism to make goal-directed corrections in movements to optimize effort. Dexterous movements are smooth and effective and accomplish the same goal with less energy than less dexterous movements. Dexterity develops during the later phases of refining a m...
