Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.5 to 1.15 million years ago. [1] The holotype specimen , OH 5 , was discovered by palaeoanthropologist Mary Leakey in 1959 at Olduvai Gorge, Tanzania and described by her husband Louis a month later.
A P. aethiopicus ulna, on the other hand, shows more similarities to Homo than P. boisei. [46] Paranthropus were bipeds, and their hips, legs and feet resemble A. afarensis and modern humans. [48] [49] The pelvis is similar to A. afarensis, but the hip joints are smaller in P. robustus. The physical similarity implies a similar walking gait. [50]
Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines". [ 10 ] [ 11 ] The australopithecines occurred in the Late Miocene sub-epoch and were bipedal , and they were dentally similar to humans, but with a brain size not much larger than that of ...
Homo erectus, a direct ancestor of humans, lasted for a million more years, while Paranthropus boisei went extinct within the next few hundred thousand years. The reason why remains a mystery, and ...
Homo erectus went on to thrive for 1 million years more. Paranthropus boisei, however, went extinct within the next few hundred thousand years. ... P. boisei and H. erectus “were similar enough ...
Oldowan tools occur in Beds I–IV at Olduvai Gorge. Bed I, dated 1.85 to 1.7 mya, contains Oldowan tools and fossils of Paranthropus boisei and Homo habilis, as does Bed II, 1.7 to 1.2 mya. H. habilis gave way to Homo erectus at about 1.6 mya, but P. boisei persisted. Oldowan tools continue to Bed IV at 800,000 to 600,000 before present . A ...
Initially, anthropologists were largely hostile to the idea that these discoveries were anything but apes, though this changed during the late 1940s. [ 17 ] In 1950, evolutionary biologist Ernst Walter Mayr said that all bipedal apes should be classified into the genus Homo , and considered renaming Australopithecus to Homo transvaalensis . [ 18 ]
Paranthropus boisei, the last species included in the genus Paranthropus, was first found in Olduvai Gorge, Tanzania and around Ethiopia and Kenya. [10] P. boisei was known for massive facial and dental bones and structure, primarily larger mandibles, molars, and premolars, which was an adaptation allowing them to consume hard plant foods with ...
