Andrews P, Tobien H. Hominid brains appear to have remained fairly constant in size for a long period from some 1.8 million years ago until about 600,000 years ago. The evidence for stone tools associated with Ramapithecus was never very convincing and with the more complete discoveries this assertion too was debunked and dismissed. answered Sep 5, 2019 by Rishab (67.7k points) selected Sep 5, 2019 by Vikash Kumar . * Ape like, hairy arms and legs of same length, large brain, ate soft fruits and leaves, walked like gorillas and chimpanzees. Best answer. Afarensis lived in open grasslands. Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa.The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s. Ardipithecus ramidus was first reported in 1994; in 2009, scientists announced a partial skeleton, nicknamed ‘Ardi’. The bulge of Broca's area, essential for speech, is visible in one habilis brain cast, and indicates it was possibly capable of rudimentary speech. These species possessed adeeper jaw, had teeth with small canines, flattened 4 molars and thickenamel 5 . The Neanderthal man with a brain size of 1400cc lived in near east and central Asia between 40,000-1,00,000 years back. and an endocast shows some frontal lobe features not seen in australopithecines and supposedly characteristics of Homo sapiens. The initial interpretation of Ramapithecus as a hominid They didnot walk upright and were similar in size to the chimpanzee, but stockier 3 .They were present about 15 million years ago. The size of their ancestor, which may be human's ancestors as well, was really small million of years ago. Ramapithecus was more man-like while Dryopithecus was … 1 Answer +1 vote . Few fossils of man-like bones have been discovered in Ethiopia and Tanzania. Gingerich PD. The brain size is very small, at 410 cc, and parts of the skull, particularly the hind portions, are very primitive, most resembling afarensis. It had large brain, a large muzzle and large canines. The importance of Ramapithecus has traditionally been in the claim that it represents the earliest hominid. It was arboreal, knuckle-walker and ate soft fruits and leaves. It was without browridges. After years of searching Indonesia for ‘the missing link’, Dutchman Eugene Dubois finally uncovered part of a skull in 1891 (known as ‘Java Man’). However, smaller mouths and teeth also indicated that early humans had softer diets than their evolutionary ancestors. 1970 Nov 7; 228 (5271):537–540. The brain size varied between 750 and 1200 CC (ours 1450 CC). A large brain capable of processing new information was a big advantage during times of dramatic climate change. A developmental model for the evolution of language and intelligence in early hominids - Volume 2 Issue 3 - Sue Taylor Parker, Kathleen Rita Gibson The brain case is rounded, and resembles an enlarged, allometrically scaled version of A. africanus. Chimpanzee's brain's size underwent directional selection. Ramapithecus strongly suggests the exploration of new dietary sources, which indicates a shift from softer forest fruits and vegetables relied upon by the apes. Dryopithecus was of the many prehistoric primates of the Miocene epoch and was a close contemporary of Pliopithecus.These tree-dwelling apes originated in eastern Africa about 15 million years ago, and then, much like its hominid descendants millions of years later (although Dryopithecus was only remotely related to modern humans), the species radiated out into Europe and Asia. It has been suggested that these imply speech capabilities. Other characteristics, like the massiveness of the face, jaws and single tooth found, and the largest sagittal crest in any known hominid, are more reminiscent of A. boisei (Leakey and Lewin 1992). When did human brain size increase? The discovery of limb bones showed the creature was not at all bipedal, and it was found to have a rather small brain size. Much of the reason for the smaller mouths was due to the increase in brain size and cranial capacity. From these few bones, some textbooks boast pictures of what a Ramapithecus “would have” looked like. The brain shape is also more humanlike. The mandible (lower jaw) of H.Erectus is heavily constructed and lacks a chin (mental eminence). Characteristics of Neanderthal Man : - * It evolved around 1,00,000-40,000 year ago.

Dryopithecus is a genus of extinct great apes from the middle–late Miocene boundary of Europe 12.5 to 11.1 million years ago (mya). Brain size: about 385-550cm 3 Height: about 1-1.7m (females were much shorter than males) Weight: about 25-64kg (females were significantly smaller than males) Diet: plants including grasses, fruits and leaves Species named in: 1978, four years after the discovery of Lucy; Name meaning: 'southern ape from Afar' (Afar is a region of Ethiopia) Information was a big advantage during times of dramatic climate change evolutionary ancestors canines.
