Natural Language and Natural Selection
Many 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. Others have argued that a biological specialization for grammar is incompatible with every ten...
متن کاملGrandmothering and natural selection.
Humans are unique among primates in that women regularly outlive their reproductive period by decades. The grandmother hypothesis proposes that natural selection increased the length of the human post-menopausal period-and, thus, extended longevity-as a result of the inclusive fitness benefits of grandmothering. However, it has yet to be demonstrated that the inclusive fitness benefits associat...
متن کاملMaladaptation and natural selection.
The transformations George Williams initiated in evolutionary biology seem so blindingly obvious in retrospect that they spur the question of why he saw what no one else did. While most humans are prone to see only what theory predicts, Williams sees in bold relief whatever does not fit. Not an adaptationist or an anti-adaptationist, Williams is better described as a maladaptionist. The challen...
متن کاملNatural selection and speciation.
A paper by Korol et al. (1) in this issue demonstrates significant premating reproductive divergence between Drosophila melanogaster populations adapted to distinct, but closely adjacent, habitats in ‘‘Evolution Canyon’’ on Mt. Carmel, Israel. The authors suggest that reproductive isolation has evolved in situ as a result of adaptive divergence in response to the contrasting environments of nor...
متن کاملLogic and Natural Selection
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. This means that knowledge of (the laws of) logic is inseparable from the po...
