Natural language and natural selection
Behavioral and Brain Sciences, 1990AbstractMany people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form.

Natural Selection on an Isoallele
Nature, 1963IN Drosophila pseudoobscura a genetic factor has previously been described1, the only observable effect of which is to cause a small change in the banding pattern of the third polytene chromosome. This factor behaves in crosses as a simple recessive gene, and has been named ‘salivary’ (sal).

Natural Selection—its power compared with man’s selection—its power on characters of trifling importance—its power at all ages and on both sexes—Sexual Selection—On the generality of intercrosses between individuals of the same species—Circumstances favourable and unfavourable to Natural Selection, namely, intercrossing, isolation, number of ...

Measurement of Natural Selection in Natural Populations
Nature, 1964VAN VALEN1 has proposed a measure of natural selection intensity as an extension of Haldane's2 measure of intensity I and applied this to data on fossil horses. Van Valen's measure, at least in the example given, is actually a special case of Haldane's I.

Synthese, 1963
There is an old philosophical argument based upon the assumption that a good design presupposes an intelligent agency. If we encounter efficient machines, we must assume an intelligent planner. In the nineteenth century, biologists discounted this assumption.

Nature, 1998
Evidence indicates that the Earth self-regulates at a state that is tolerated by life, but why should the organisms that leave the most descendants be the ones that contribute to regulating their planetary environment? The evolving Gaia theory focuses on the feedback mechanisms, stemming from naturally selected traits of organisms, that could generate ...

Logica Universalis, 2010
Is logic, feasibly, a product of natural selection? In this paper we treat this question as dependent upon the prior question of where logic is founded. After excluding other possibilities, we conclude that logic resides in our language, in the shape of inferential rules governing the logical vocabulary of the language.

Scientific American, 2009
This article discusses the development of evolutionary genetics as a science that analyzes the regulation of genetic mutations through natural selection. Research into DNA and the role of genetic fitness in the regulation of mutations is considered. Examples from microbial and plant genetics are presented.

BioEssays, 2000
We review the various factors that limit adaptation by natural selection. Recent discussion of constraints on selection and, conversely, of the factors that enhance "evolvability", have concentrated on the kinds of variation that can be produced. Here, we emphasise that adaptation depends on how the various evolutionary processes shape variation in ...
