Greater female communalities in prenatal hand and dental development
(Elsevier, 1974-06)
As shown in 15 male and 17 female developmentally-normal, 6-9 week (15-47 mm crown-rump length) embryos, intercorrelations (communalities) involving both mesial and distal deciduous teeth and proximal and distal segments ...
Developmental responses to high altitude hypoxia
(Wiley Subscription Services, Inc., A Wiley Company, 1970-05)
From a review of published literature on developmental responses to high altitude, three major conclusions are derived. First, the small birth weight of high altitude native populations are adaptive responses to reduce the ...
Applications of radiodermatography to human and primate studies
(Wiley Subscription Services, Inc., A Wiley Company, 1970-07)
Using 325-mesh tantalum powder as a contrast medium, it is possible to take high-resolution “radiodermatographs” of man and infra-human primates that combine the advantages of postero-anterior hand radiographs and conventional ...
Economic impact on tooth emergence
(Wiley Subscription Services, Inc., A Wiley Company, 1973-09)
As shown in nearly 10,000 Negro and White boys and girls between 4.5 and 16.5 years of age, poverty-level children (with an income-to-needs ratio of 1.0) tend to be delayed in permanent tooth emergence as compared with ...
Dental reduction and the probable mutation effect
(Wiley Subscription Services, Inc., A Wiley Company, 1975-09)
A recent test of the probable mutation effect can be interpreted to suggest the operation of mutations under conditions of reduced selection in the late Pleistocene reduction of the human dentition.
A-B-O and Rh affinities between highland and lowland Quechua-speaking Peruvian populations
(Wiley Subscription Services, Inc., A Wiley Company, 1975-09)
According to the accounts of the Spanish chronicles and various historical analyses the Quechua-speaking population inhabiting the Province of Lamas in the Eastern Tropical Lowlands of Peru are descendants of the Chanca ...

Krapina, "Classic" Neanderthals, and the evolution of the European face,
(Elsevier, 1979-07)
Except for the front end of the dental arch, tooth size remained at approximately the same level throughout the Middle Pleistocene. The Krapina Neanderthals at the end of the last interglacial differed from Homo erectus ...
Developmental adaptation to high altitude hypoxia
(Springer-Verlag; Swets & Zeitlinger B.V., 1977-06)
Experimental studies on animals and humans exposed to hypoxic stress have been reviewed. These data suggest that the influence of hypoxic stress, and the organism's response to it, are greater during growth than during ...
The sex difference in dimensional communalities in Macaca nemestrina
(Wiley Subscription Services, Inc., A Wiley Company, 1975-07)
Intra-individual correlations for cranial, mandibular and dental measurements made on lateral skull radiographs of Macaca nemestrina were systematically higher in 30 adult females than in 31 adult males by an average of ...
