Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines". [ 11 ] [ 12 ] 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 ...
The robust Paranthropus boisei (left) vs the gracile A. anamensis (right) Australopithecus species are thought to have eaten mainly fruit, vegetables, and tubers, and perhaps easy-to-catch animals such as small lizards.
However, it has been argued by some that Paranthropus is an invalid grouping and synonymous with Australopithecus, so the species is also often classified as Australopithecus robustus. Robust australopithecines—as opposed to gracile australopithecines—are characterised by heavily built skulls capable of producing high stresses and bite ...
They are also referred to as the robust australopithecines. They lived between approximately 2.9 and 1.2 million years ago (mya) from the end of the Pliocene to the Middle Pleistocene . Paranthropus is characterised by robust skulls , with a prominent gorilla -like sagittal crest along the midline—which suggest strong chewing muscles—and ...
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]
However, it is also argued that Paranthropus is an invalid grouping and synonymous with Australopithecus, so the species is also often classified as Australopithecus boisei. Robust australopithecines are characterised by heavily built skulls capable of producing high stresses and bite forces , and some of the largest molars with the thickest ...
The brain space of the skull, and so most likely the brain itself, were larger than in modern humans. When comparing traits to worldwide average present day human traits in Neanderthal specimens, the following traits are distinguished. The magnitude of particular trait changed over the 300,000-year timeline of Neanderthal evolution.
These two specimens were also robust, but the skulls were considered more gracile. The smaller skulls are evidence that sexual dimorphism was the reason for the size difference. Consistent evidence of Lower Pleistocene hominids supports that there was a variation in size of the Australopithecus in East Rudolf, and not a separate species. [4]
