Hoc alterum auditus organi ossiculum est: Ear Ossicles in Physical Anthropology
Human Evolution - Tập 21 - Trang 1-17 - 2006
In spite of the importance of auditory ossicles in anthropological studies, very little attention has been paid to these bones, which are only rarely recovered in archaeological excavations and in osteological collections. In this paper, we attempt to review some studies that started in the 1960 from when we first collected and prepared ossicles from the early Egyptian osteological collection of G......
Geology and fauna of the middle Miocene hominoid site at Muruyur, Baringo district, Kenya
Human Evolution - Tập 3 - Trang 381-390 - 1988
The middle Miocene sediments assigned to the Muruyur Beds have yielded abundant faunal remains which indicate an age somewhere near the early part of the middle Miocene, perhaps being earlier in time than Fort Ternan but probably coeval or slightly later than Maboko. Available radioisotopic age determinations suggest that the beds are between 13.5 and 14 m.y. old, which seems to be too young when ......
Hominid origins: Neontology, palaeontology, palaoenvironment & history

Paracentric inversions in human chromosome 7 as a graphic example of reverse chromosomal mutation
Human Evolution - Tập 2 - Trang 321-327 - 1987
A famillialy inherited paracentric inversion of human chromosome 7 is described. The breakpoints are localized in the bands q1 1.2 and q2 2.1. The similarity between the inverted chromosome 7 and the chromosome 6 of the gorilla characterizes this inversion as a reverse chromosomal mutation. The parallels between human chromosome pathology and the chromosomal evolution of Pongidae and man are discu......
Punctuationism, cladistics and the legacy of medieval neoplatonism
Human Evolution - Tập 3 - Trang 121-139 - 1988
The current dominant orthoxy in paleoanthropology has adopted the stance of cladistics and/or punctuationism and abandonned any concern for the mechanics by which selection has operated to control the course of human evolution. Rather than being a «new» intellectual development, this is simply the most recent manifestation of a tradition of thinking that goes back via Linnaeus to medieval scholast......
On the trends of the evolutionary radiation on the Tonkin leafmonkey (Presbytis francoisi, primates: cercopithecidae)
Human Evolution - Tập 4 - Trang 501-507 - 1989
On the basis of taxonomic, ecological and geological data, a hypothesis is presented on the trends of evolutionary radiation of the Tonkin leafmonkey (Presbytis francoisi). The ancestral form was mainly black likeP. f. hatinhensis and located in the limestone hilly regions of Northern Annam. The range expanded at the end of the upper Pleistocene, and subspeciation occurred at the beginning of the ......
Origin and development of Tool-making behavior in Africa and Asia
Human Evolution - Tập 15 - Trang 121-128 - 2000
Around two-and-a-half million years ago, some hominid populations in Africa began to modify stones and bones in a manner that can be recognized by prehistorians as artifacts, and, by definition, produced the earliest identifiable archaeological record. It is likely that earlier hominid groups also may have had relatively rich tool-using behavioral repertoires similar to that seen in modern chimpan......
Non-mental aspects of encephalisation: The forebrain as a playground of mammalian evolution
Human Evolution - Tập 4 - Trang 45-53 - 1989
Neo-darwinian theory holds that changes in mammalian and avian body morphology follow behavioral adaptation. The problem then is to explain how random mutations can result in a sufficiently rapid reorganization of the most complex biological system —common sense would predict that the CNS is the slowest to evolve. This paper attempts a parsimonious explanation which predicts that the accumulation ......
Aerobic power and anthropometric characteristics of Hungarian schoolboys
Human Evolution - Tập 13 - Trang 97-105 - 1998
A sample of 989 male youngsters aged 11–18 years was subdivided into three groups by the type and amount of their physical activity as follows. Group 1 (G1) had a maximum of three curricular PE classes a week, without any additional organized physical activity. With the same number of PE lessons Group 2 (G2) had at most three sessions of sports training per week in addition. Group 3 (G3) had a wee......
