Within the context of the study of the genetics of language, Chomskian laws of grammar, such as theStructure-dependence Condition and theA over A Condition, may be usefully regarded to have a status similar to that of Mendelian Laws in classical genetics. In both the case of Chomsky's Laws and Mendel's Laws, formal genetic principles are postulated which abstract away from the physical mechanisms involved and in both cases certain apparent counterexamples mirror a more complex underlying genetic organisation.

Offers an overview of work on the biology of language - what is sometimes called the "biolinguistic approach." This book focuses on the interplay between variation and the universal properties of language. It provides case studies from the areas of syntactic variation, genetic variation, neurological variation and historical variation.

The burgeoning field of studies in expertise and experience is a useful theoretical approach to complex problems. In light of SEE, examination of the controversial and well known case study of dolphin bycatch in the US tuna fishery, reveals that effective problem-solving was hindered by institutional tensions in respect of decision-making authority and difficulties with the integration of different expertises. Comparing the profiles of four individuals, who played distinct roles in the problem-solving process, I show that to address a complex (...) problem, a suite of contributory expertises—rarely found in one individual—may be required; formal credentials are not a reliable indicator of who possesses these necessary expertises; interactional expertise and interactive ability are useful tools in combining the contributory expertises of others to yield a desirable collective outcome; and the concepts of contributory expertise and no expertise are useful tools for understanding the actual contribution of various parties to the problem-solving process.Keywords: Expertise and experience; Bycatch; Tuna-dolphin; Invention; Conservation technology; Interactional expertise.

This paper explores the evolution of a trading zone by organizing the case study of turtle excluder devices within the model proposed by Collins et al.. The case study offers evidence that trading zones do evolve and that the concepts of enforced and fractionated trading zones hold practical utility for describing and defining the complexities of actual exchanges. In this case a trading zone evolved from enforced to fractionated and ultimately diverged into two trading zones. For each step of the (...) evolution I describe the forces that drove these transitions. Finally, I present an adapted trading zone model that is conceptually a better fit for the turtle excluder device case study.Keywords: Trading zones; Interactional expertise; Turtle excluder device; Bycatch.
