These proposed relationships were contradicted by results from comparative immunology (i.e. the molecular clock), which indicated that the last common ancestor of all living hominoids originated between 15 and 12 million years ago (ma), whereas humans diverged from gorillas and chimpanzees about 5 ma (1 10, ).

Proconsulidae is an early family of primates that lived during the Miocene epoch in Kenya, and was restricted to family is split into two subfamilies. Members of the family have a mixture of Old World monkey and ape characteristics, so the placement in the ape superfamily Hominoidea is tentative; some scientists place Proconsulidae outside of Hominoidea in a separately superfamily Class: Mammalia.

The well-known fossil reappraisal of taxonomic relationships among proposed Miocene hominoids book Proconsul from the Early Miocene of Kenya was a non-specialized arboreal quadruped with strong pollicial/hallucial assisted grasping capability.

It lacked most of the suspensory specializations acquired in living hominoids. Nacholapithecus, however, from the Middle Miocene of Kenya, although in part sharing with Proconsul the common primitive anatomical body Cited by: Middle and Late Miocene taxa are clearly hominoids, and by the end of the Middle Miocene, most can be attributed to either the pongine (Pongo) or hominine (African ape and human) clade.

Interestingly, there is no definitive fossil record of the hylobatid clade (gibbons and siamangs), though there have been some proposed candidates. The Miocene was the most diverse era in hominoid evolutionary history.

Miocene hominoids exhibit a level of taxic, morphological, and biogeographic diversity that far exceeded that of living apes. Over 30 genera of Miocene apes are currently recognized (Begun, a); probably only a small percentage of those that by: 3.

Proconsul is one of the best represented Miocene hominoid in the fossil record. It lived from approximately 23 to 14 million years ago. From the full arrray of remains it has been shown that there was considerable variation in this genus.

Body sizes ranged from that of a small monkey (10 pounds) to that of a female gorilla ( pounds). Hominoid taxonomies 1 August ScienceWeek. The terms "hominoid", "hominid", and "hominin" are not interchangeable, but their classification criteria are variously in a state of flux.

In general, the hominoids are a primate superfamily; the hominid family is currently considered to comprise both the great ape lineages and human lineages.

A reappraisal of early hominid phylogeny. We report here on the results of a new cladistic analysis of early hominid relationships. T.A. Naiman, F.E. GrineBasicranial variation among extant hominoids and fossil hominids. phys. Anthrop, 78 (), pp.

Cited by: Human evolution from its first separation from the last common ancestor of humans and chimpanzees is characterized by a number of morphological, developmental, physiological, and behavioral changes.

The most significant of these adaptations are bipedalism, increased brain size, lengthened ontogeny (gestation and infancy), and decreased sexual dimorphism. The relationships among modern humans and the great apes. The approximate dates of each hypothetical common ancestor are based on the references cited in the text.

In version A the only options for a 5 Ma fossil species that shares more morphology with modern humans and chimpanzees/bonobos than with gorillas is to be an ancestor of modern Author: B.

Wood, E. Boyle. The Miocene was first recognized and defined by Charles Lyell in the early nineteenth century. While examining rocks in the Paris Basin, he noted that different strata contained varying percentages of living mollusc species.

The Miocene consisted of layers in which only 18% of the fossils were represented among living mollusc species. MOST reviewers of East African early Miocene apes have been impressed by their similarity, as an adaptive array, to living Cebidae.

These apes are. Molecular studies suggest that the lineages leading to humans and chimpanzees diverged approximately – million years (Myr) ago, in the Late Miocene1,2,3.

In addition to her work on the Miocene hominid fossil record, Mary Leakey contributed to archaeology through her discovery of the earliest direct evidence of hominid activity and through her painstaking documentation of East African cave paintings.

Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus Homo – and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.

This process involved the gradual development of traits such as human bipedalism and language.proposed (Pawlowski et al.,Mar. Micropaleont.).
