Baboons

As adults, yellow baboons (Papio cynocephalus) walk using digitigrade hand and semiplantigrade/digitigrade foot postures. Hand and foot posture is more variable in infant baboons, who also walk with more flexed knee postures. In the forelimb, digitigrade hand postures and extended elbows function to increase relative ELL at slow walking velocity. Increased forelimb ELL may be an attempt to equalize forelimb and hind limb ELLs in baboons with an absolutely longer hind limbs.

Future work will examine the ontogeny of COM movements in hamadryas baboons
