Human tree climbing abilities
A study reports that the muscle architecture of Twa honey-gatherers, a population of former hunter-gatherers in Uganda, may enable their extraordinary degree of ankle dorsiflexion during tree climbing, a degree similar to that observed in wild chimpanzees, suggesting that a foot adapted to bipedalism may not have necessarily constrained tree climbing abilities. -
