Ancient hominin bones found at the Sterkfontein Cave site in South Africa suggest some early humans were still regularly climbing trees as many as 2 million years ago. Based on the characteristics of the footprints, Mary Leakey concluded that their makers were adults

Homo Erectus “Upright man” stood about 5 and a half feet in height. Evidence that it is a hominin: femur shape, pelvis shape, and position of foramen magnum all show it was a facultative biped Despite prevailing regional aridity since the mid-Miocene, data show that early hominins Sahelanthropus tchadensis, Orrorin tugenensis, and Ardipithecus ramidus lived in environments made of mosaics of grasslands, mixed grasslands, woodlands, and forests, where … oldest fossil hominins have been recovered from sites in East Africa, especially in the

presumably earlier human-like forms from Java, in Southeast Asia. The earliest sites found in Eurasia show that the technological strategies that early hominins were utilizing were similar to some of the earliest strategies evidenced from Africa.

Match each species of pre-australopithecine to the appropriate map showing where its fossil remains have been found. Discovery of Early Hominins The immediate ancestors of humans were members of the genus Australopithecus.The australopithecines (or australopiths) were intermediate between apes and people. in the Middle Awash Valley of Ethiopia that remains problematical. While Neanderthal DNA is present in all populations outside of Africa, Denisovan DNA is only found in modern populations from China, island Southeast Asia, and Oceania. open environments, bipedalism would very likely have been an advantage. Introduction a) All the early hominins are found exclusively in Africa. The short term for Homo Neander-thalensis is “Neanderthals”. This trait supports classifying its species as an early hominid, some scientists now argue. Tim White, now a professor at the University of California, Berkeley, announced the discovery

They modeled the energy cost of walking and found that long-legged hominins are energetically efficient because they walk with straight legs, with their knees directly over their lower legs. Many thousands of bone fragments, including the remains of 130 individual hominins, were recovered
