Homo naledi evolved from the robust Australopithecines. Implementing them into a leg workout may look something like this: The Zercher squat is its own thing, but it doesnt mean you cant apply the Zercher carry position to other movements to get similar benefits. [52], Dentally, H. erectus have the thinnest enamel of any PlioPleistocene hominin. [138] However, this ancestor may have instead been H. heidelbergensis, as a hyoid bone of a 530 ka H. heidelbergensis specimen from the Spanish Sima de los Huesos Cave is like that of modern humans,[139] and another specimen from the same area shows an auditory capacity sensitive enough to pick up human speech.
