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 tenet of Darwinian theory – that it shows no genetic variation, could not exist in any intermediate forms, confers (...) no selective advantage, and would require more evolutionary time and genomic space than is available. We examine these arguments and show that they depend on inaccurate assumptions about biology or language or both. Evolutionary theory offers clear criteria for when a trait should be attributed to natural selection: complex design for some function, and the absence of alternative processes capable of explaining such complexity. Human language meets these criteria: Grammar is a complex mechanism tailored to the transmission of propositional structures through a serial interface. Autonomous and arbitrary grammatical phenomena have been offered as counterexamples to the position that language is an adaptation, but this reasoning is unsound: Communication protocols depend on arbitrary conventions that are adaptive as long as they are shared. Consequently, language acquisition in the child should systematically differ from language evolution in the species, and attempts to analogize them are misleading. Reviewing other arguments and data, we conclude that there is every reason to believe that a specialization for grammar evolved by a conventional neo-Darwinian process. (shrink)

Despite the declarations of international documents on minority language rights, provision is patchy for supporting minority languages in the UK, where since the 1980s governments have deliberately or unwittingly greatly raised the profile and comparative standing of English. The partial exception to this trend has been the treatment of indigenous/regional minority languages, stimulated by policies of devolution intended to revive or create a sense of national identity, and to redress perceived historic linguistic injustices. In a multicultural state or region these (...) apparently reasonable goals appear to conflict with current views of citizenship that argue for inclusiveness and equal treatment for all under the law. In particular, the question arises why indigenous minority languages should receive official support and funding that is denied to speakers of minority ethnic languages. In this article, I examine various justifications offered for this, including higher population levels, the geographical concentration of indigenous speakers, the long historical ties between regional language and culture, and the notion of promotional rights. I attempt to show each argument lacks force and ignores the fact of natural language change. I argue for an approach to indigenous languages that weights support and funding according to a range of factors including the number of minority speakers, their perceived need and the benefits that would flow from funding. Support from the local community and private sources could also be encouraged. (shrink)
