It was once thought that Paranthropus had become a specialist feeder, and were inferior to the more adaptable tool-producing Homo, leading to their extinction, but this has been called into question. [ 32 ] [ 60 ] [ 61 ] [ 63 ] [ 67 ] However, smaller brain size may have been a factor in their extinction along with gracile australopithecines ...
Paranthropus aethiopicus is an extinct species of robust australopithecine from the Late Pliocene to Early Pleistocene of East Africa about 2.7–2.3 million years ago. However, it is much debated whether or not Paranthropus is an invalid grouping and is synonymous with Australopithecus, so the species is also often classified as Australopithecus aethiopicus. [1]
Prehistoric religion is the religious practice of prehistoric cultures. Prehistory, the period before written records, makes up the bulk of human experience; over 99% of human experience occurred during the Paleolithic period alone.
Australopithecus fossils become more widely dispersed throughout eastern and southern Africa (the Chadian A. bahrelghazali indicates that the genus was much more widespread than the fossil record suggests), before eventually becoming pseudo-extinct 1.9 million years ago (or 1.2 to 0.6 million years ago if Paranthropus is included).
It was long assumed that if Paranthropus is a valid genus then P. robustus was the ancestor of P. boisei, but in 1985, anthropologists Alan Walker and Richard Leakey found that the 2.5-million-year-old East African skull KNM WT 17000—which they assigned to a new species A. aethiopicus|A. aethiopicus—was ancestral to A. boisei (they ...
It became extinct in Africa c. 1.5 Ma, [53] but had already moved out through the Sinai, and is among the faunal remains of the Levantine hominin site of Ubeidiya, c. 1.4 Ma. [27] It could not break bone marrow and its kills were likely an important food source for hominins, [ 54 ] especially in glacial periods. [ 55 ]

[47] [48] Brain expansion (enlargement) between 0.8 and 0.2 Ma may have occurred due to the extinction of most African megafauna (which made humans feed from smaller prey and plants, which required greater intelligence due to greater speed of the former and uncertainty about whether the latter were poisonous or not), extreme climate variability ...
