Recent discoveries in a broad range of disciplines have raised important questions about the influence of ecological factors in early human evolution. S25, p. 201. One of the key physiological differences between early humans (Homos) and Australopithecines was adult cranial capacity. Paranthropus robustus is a species of robust australopithecine from the Early and possibly Middle Pleistocene of the Cradle of Humankind, South Africa, about 2 to 1 or 0.6 million years ago.It has been identified in Kromdraai, Swartkrans, Sterkfontein, Gondolin, Cooper's, and Drimolen Caves.

PiltdownThe _____________ hypothesis proposed by Owen Lovejoy states that the advantages of males carrying food and bringing it to females and young could have contributed to the rise of bipedalism. Paranthropus is characterised by robust skulls, with a prominent gorilla -like sagittal crest along the midline–which suggest strong chewing muscles–and broad, herbivorous teeth used for … QUESTION 35 What do the distinctive traits of robust australopithecines include? Robust refers to the heavily built mandible, crested cranium, and … Au. Dental morphological traits that are of interest in human populations today can be seen in the fossil record beginning with the Australopithecines between 4 and 1 million years ago (Schroer and Wood, 2013), and some traits occur even earlier in primate evolution, such as the Y-5 pattern during the Miocene (Pilbeam et al., 1977). In modern populations, males are on average a mere 15% larger than females, while in Australopithecus, males could be up to 50% larger than females by some estimates. Before hominids made stone tools, they probably: used sticks or other perishable materials.

Lewin, Roger and Robert Foley 2004 Principles of Human Evolution (2nd edition). d. a big face, large teeth, and a large body. They are our distant ‘cousins’ rather than our direct relatives. The genus Australopithecine includes hominins that lived about. Along with other distinct traits, robust australopithecines had large _____ adapted for grinding food. Australopithecus aethiopicus (2.7–2.3 mya), formerly known as Paranthropus aethopicus, is the earliest of the so-called robust australopiths, a group that also includes A. robustus and A. boisei (described below). Australopithecines include a variety of species, each experimenting in being a bipedal capable of exploiting a range of dietary resources including tough or hard-to-chew foods when necessary, yet without having become encephalized to the extent seen in Homo (Hammond and Ward, 2013). They lived between approximately 2.6 and 0.6 million years ago (mya) from the end of the Pliocene to the Middle Pleistocene . question. the discovery of Kenyanthropus Platyops was important because. The robust australopithecines were a side branch of human evolution. Three cranial traits used to differentiate gracile and robust Australopithecines include the robust Australopithecine having a sagittal crest, a more robust mandible, and a flatter face, where the gracile has no sagittal crest, a less robust mandible, and more visible prognathism. The earliest evidence of fundamentally bipedal hominids can be observed at the site of Laetoli in Tanzania. Following a recent influx of fossils (e.g., Brown et al., 2004; Lordkipanidze et al., 2013; Villmoare et al., 2015a; Berger et al., 2015) the amount of diversity in fossil morphology has increased … 4 to 1 mya. it shows diversity in the hominin fossil record 3.5 mya Some are called robust australopithecines (australopiths) because they had heavy features and large jaws with powerful muscles for smashing and grinding tough food. aethiopicus. The robust australopithecines all became extinct between 1.5 and 1 million years ago, while one of the gracile autralophithecines is believed to have given rise to the branch leading to the emergence of the genus Homo c.2.5 million years ago. & large premolars and molars large temporalis muscles and a sagittal crest The earliest hominins probably lived in which kind of environment?
