Despite scientific evidence suggesting close phylogenetic relationship between chimpanzees and humans, the inclusion of these apes in the genus "Homo" is controversial. Several tools have been used to analyse this issue such as fossils, molecular clock and genome. This work intended to understand the biology teachers' conceptions about…

The model presents neurobiologically plausible accounts of sound recognition (including absolute pitch), neural plasticity involved in pitch, loudness and location information integration, and streaming and auditory recall. It is proposed that a cortical mechanism for sound identification modulates the spectrotemporal response fields of inferior…

This article is about whalesongs, hearing, musical brains, and a number of other topics explored over the past 35 years. Previous research is reviewed briefly, and more attention is given to recent efforts with an emphasis on collaborative research conducted with many wonderful colleagues. First is a brief account of the Institute for Music…

Considers natural and cultural environmental factors likely to have been responsible for reduction in size of hominid teeth and simplification of their morphology during the Pleistocene. Cites fossil evidence and postulates selective mechanisms. (EB)

The study describes the process of DNA-DNA hybridization and the history of its use by Sibley and Alquist in simple, straightforward, and interesting language that students easily understand to create their own phylogenetic tree of the hominoid superfamily. They calibrate the DNA clock and use it to estimate the divergence dates of the various…

Presents current scientific evidence of a possible ancestor of the Homo genus. (WRM)

We studied economic choice behavior in capuchin monkeys by offering them to choose between two different foods available in variable amounts. When monkeys selected between familiar foods, their choice patterns were well-described in terms of relative value of the two foods. A leading view in economics and biology is that such behavior results from…

Describes two undergraduate courses in primate behavior, which emphasize hierarchy status, learning communications systems, social behavior, and ecological relationships of primates. Included is an extensive listing of resources for primate behavior. (SL)

Contains a description of the organization of the Primate Research Centers and some of the research being conducted there. (CP)

Provides synoptic lesson plans, and detailed lists of resources, for a unit in primate behavior taught to students in grades 4-6. Comparisons with man are made wherever possible. (AL)

Discusses the continuing debate over the existing social relations between the sexes; that is, whether subordination of females to males is derived from biological differences or is brought about as a result of the existing social structure. (SB)

Studies of the biology of music (as of language) are highly interdisciplinary and demand the integration of diverse strands of evidence. In this paper, I present a comparative perspective on the biology and evolution of music, stressing the value of comparisons both with human language, and with those animal communication systems traditionally…
