Ramapithecus | Early Human Ancestor, Fossil Primate Genus
Ramapithecus, fossil primate dating from the Middle and Late Miocene epochs (about 16.6 million to 5.3 million years ago). For a time in the 1960s and ’70s, Ramapithecus was thought to be a distinct genus that was the first direct ancestor of modern humans (Homo sapiens) before it became regarded as that of the orangutan ancestor Sivapithecus.

2018年5月8日 · Ramapithecus (räməpəthē´kəs, –pĬth´ə–), an extinct group of primates that lived from about 12 to 14 million years ago, for a time regarded as a possible ancestor of Australopithecus [1] and, therefore, of modern humans.
Australopithecus vs. Ramapithecus - What's the Difference ...
Australopithecus and Ramapithecus are two important hominid species that played significant roles in the study of human evolution. While both species belong to the same family tree, they have distinct attributes that set them apart.
The initial interpretation of Ramapithecus as a hominid ancestor was completely within this Darwinian framework, just as were the initial interpretations of Australopithecus africanus (Dart 1925) and Gigantopithecus blacki (Wu 1962). Thus, the characteristics Lewis (1934) emphasized in his hominid inter-

2010年7月27日 · Formerly known as the australopithecines, they are not a “natural” group, in that they do not represent all of the descendants of a single common ancestor (i.e., they are not a “clade”). Rather, they are grouped together informally because nearly all share a similar adaptive grade (i.e., they have similar adaptations).
Fossil apes and human evolution | Science - AAAS
2021年5月7日 · In 1965, Simons and Pilbeam revised and organized available Miocene apes in three genera: Dryopithecus, Gigantopithecus, and Ramapithecus. The genus Sivapithecus was included in Dryopithecus, considered the ancestor of African apes, whereas Ramapithecus was considered ancestral to humans based on its short face (and inferred small canines) .
Ramapithecus and hominoid evolution - ScienceDirect
1982年9月1日 · The phylogenetic affinites of Ramapithecus have been debated since its initial description in the 1930s. The concensus view that Ramapithecus represents the earliest hominid has been challenged by new evidence from molecular studies and the discovery of fossils which include formerly unknown parts of the facial skeleton.

Because it has been contended at various times that Ramapithecus is the earliest hominid,* these changing interpretations have in turn resulted in different theories of hominid origins. Download to read the full chapter text

Australopithecus, Meganthropus and Ramapithecus
1973年11月1日 · From South Africa we know two separate species, Australopithecus africanus and A. robustus. Robinson in a number of papers defends his view that they belong to two different genera, the "gracile" A. africanus from Taung, Sterkfontein and Makapansgat and the "robust" Paranthropus robustus from Swartkrans and Kromdraai.
