An adult male chimpanzee in the natural habitat has been observed to walk predominantly bipedally after a total forelimb paralysis in 1966. The major differences from previously described bipedal chimpanzee gait are (1) one third of the femoral extension is posterior to the hip joint in propulsion, (2) excursion of the swinging foot is close to midline, due to adduction of the lower hindlimb in swing and propulsive phases, (3) depressed pelvic tilt is on the side of the swinging limb, (4… 

Arboreal bipedalism in wild chimpanzees: implications for the evolution of hominid posture and locomotion.

Bipedalism among Bwindi chimpanzees suggests the origin of bipedal posture in hominids to be related to foraging advantages in fruit trees, and suggests important arboreal advantages in upright posture.

Locomotion in bonobos (Pan paniscus): differences and similarities between bipedal and quadrupedal terrestrial walking, and a comparison with other locomotor modes

There is great overlap between the many locomotor modes in bonobos, and that the required polyvalence is reflected in their anatomy, which may hamper the development of one highly specialized gait (i.e. bipedalism), which would constrain performance of the other types of locomotion.

Savanna chimpanzees (Pan troglodytes verus) as a referential model for the evolution of habitual bipedalism in hominids

The results of this study indicate that Fongoli chimpanzees are significantly more bipedal than chimpanzees at other sites, exhibiting a rate of 1.05 bipEDal bouts per observation hour, and suggest that both postural and locomotor bipedALism should be considered in scenarios seeking to reconstruct the evolution of bipingalism in a variety of arboreal and terrestrial contexts.

Stresses Exerted in the Hindlimb Muscles of Common Chimpanzees (Pan troglodytes) during Bipedal Locomotion

During a slow walk, untrained chimpanzees were found to exert far greater muscle stresses than humans do when running at moderate speed, particularly in the muscles that extend the hip, because of the bent-hip, bent-knee posture.

Poliomyelitis and skeletal asymmetry in Gombe chimpanzees

Comparison of left and right upper limb bone weights, lengths, joint areas, and diaphysial diameters between two adult females with long-term, partial paralysis and a group of unaffected adult Gombe chimpanzees show that the disease caused considerable asymmetries in the skeleton.

Femoral Bicondylar Angles among Dry-Habitat Chimpanzees (Pan troglodytes schweinfurthii) Resemble Those of Humans: Implications for Knee Function, Australopith Sexual Dimorphism, and the Evolution of Bipedalism

Femoral obliquity among dry-habitat chimpanzees is consistent with the hypothesis that bipedalism evolved as a dry- Habitat foraging strategy.

Coupled whole-body rhythmic entrainment between two chimpanzees

The authors' analyses show a first case of spontaneous whole-body entrainment between two ape peers, thus providing tentative empirical evidence for phylogenies of human dance, and discusses dance evolution as driven by ecologically-, socially- and/or culturally-imposed “captivity”.

The genetic basis of tail-loss evolution in humans and apes

It is proposed that selection for the loss of the tail along the hominoid lineage was associated with an adaptive cost of potential neural tube defects and that this ancient evolutionary trade-off may thus continue to affect human health today.

Trabecular bone patterning in the hominoid distal femur

A comparative sample of trabecular structure in the hominoid distal femur of extant hominoids is offered and can contribute to future studies of locomotion in extinct taxa.

Agonistic Interactions within a Winter Flock of Slate‐coloured Juncos (Junco hyemalis) Evidence for the Dominants' Strategy

The context of agonistic encounters is investigated. The success of initiated and defensive pecking is analyzed. Two classes of encounter-context are under discussion. The approaching bird chases off



Chimpanzee Bipedalism: Cineradiographic Analysis and Implications for the Evolution of Gait

The femoral head morphology in the fossil hominid Australopithecus robustus is evidence of an approximately vertical excursion of the femur in contrast to the adducted pattern of modern man and the abducted pattern of chimpanzees.

Bipedal behavior and the emergence of erect posture in man.

Bipedal behavior is present to some degree in most of the higher primates and formed part of a pattern of natural selection which shaped a physical type adapted for erect, bipedal posture.

Food Transport and the Origin of Hominid Bipedalism1

B bipedalism was the basic adaptation for the foundation of the human radiation, starting man on "his separate evolutionary path" (1959:31), though tool-using may have been almost as early (1960a) or simultaneous (Washburn and Howell 1960:3537, 47).

A biomechanical interpretation of the pelvis of Australopithecus.

Dart’s model of the Makapan ilium in a Bushman pelvis showed their morphological similarities in size and shape. The structural differences of the ilia have important implications for locomotion that
