Culture and Biological Adaptation

American Anthropologist, 1965
THE results of one phase of a recently completed study which are pertinent to the question of the biological adaptiveness of culture are presented here. For the purpose of interpreting the genetic characteristics of Pacific Island peoples, research was initially directed to the problem of identifying the determinants of size, structure and dynamics of ...

Adaptation and Optimization of Biological Transport Networks

Physical Review Letters, 2013
It has been hypothesized that topological structures of biological transport networks are consequences of energy optimization. Motivated by experimental observation, we propose that adaptation dynamics may underlie this optimization. In contrast to the global nature of optimization, our adaptation dynamics responds only to local information and can ...

Ethanol and biological membranes: Injury and adaptation

Pharmacology Biochemistry and Behavior, 1983
Ethanol intoxication affects the protein and lipid constituents of biological membranes. Mitochondria exhibit specific decreases in components of the electron transport chain and in protein synthesis. In vitro ethanol reduces the transition temperatures of membrane-bound enzyme activities and decreases the order parameter.

Biological Adaptation: A Reply

Philosophy of Science, 1972
Michael Ruse [3] has criticized the distinction between biological function and evolutionary adaptation that I argued for in my article “Biological Adaptation” [2]. I shall show below that Ruse's criticisms are not, for the most part, well taken and that the distinction remains as I made it.

Adaptive optimization and the harvest of biological populations

Mathematical Biosciences, 1996
Adaptive management of renewable biotic resources accounts explicitly for uncertainties in system responses to management and recognizes the importance of reducing uncertainties while pursuing other management goals. An adaptive approach to the harvest of wildlife populations that are subject to (1) uncontrollable environmental variation, (2 ...

Human Biological Adaptability

Science, 1969
Adaptation is an aspect of virtually all questions of human biology. Besides their interest in evolution through adaptive selection of the primates, including man, physical anthropologists are concerned with biological adaptability as a human attribute.

Genetic and Biological Aspects of Zebu Adaptability

Journal of Animal Science, 1980
The utility and documentation of traits and characteristics of Zebu, Bos indicus, cattle in beef production in the United States are discussed with reference to adaptation. Zebu cattle are uniquely suited to hot climates due to coat, hide, skin and hematological attributes.

Physical models of biological information and adaptation

Journal of Theoretical Biology, 1985
The bio-informational equivalence asserts that biological processes reduce to processes of information transfer. In this paper, that equivalence is treated as a metaphor with deeply anthropomorphic content of a sort that resists constitutive-analytical definition, including formulation within mathematical theories of information.

Adaptation? Learning? Features of biological learning

2012 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2012
All living organisms can learn the behavior appropriate to the environment. The learning process is, however, seems to be the convergence to the adapted behavior rather than learning. Living organisms can create the appropriate behavior through the behavior control in the environment.
