Looking at studies and examples from Canada to France to South Korea, The Bilingual Brain investigates the significant impact of bilingualism on daily life from infancy to old age. It reveals, among other things, how babies differentiate between two languages just hours after birth, how accent affects the way in which we perceive others and even why bilinguals are better at conflict resolution. Drawing on cutting-edge neuro-linguistic research from his own laboratory in Barcelona as well from centres across the world, and his own bilingual family, Costa offers an examination of the intricacies and impact of an extraordinary skill.

    One of Pennock's major innovations is to turn from biological evolution to the less-charged subject of linguistic evolution, which has strong theoretical parallels with biological evolution both in content and in the sort of evidence scientists use to draw conclusions about origins Several chapters deal with the work of Phillip Johnson, a highly influential leader of the new creationists. Pennock explains how science uses naturalism and discusses the relationship between factual and moral issues in the creationism-evolution controversy. The book also includes a discussion of Darwin's own shift from creationist to evolutionist and an extended argument for keeping private religious beliefs separate from public scientific knowledge.
