If temperature does not vary from one generation from to the next but its value is crucial for the development of particular phenotypic characteristics, a long-term change in its value may trigger major evolutionary changes of the organism. If a bird's nest maintains the critical temperature, then a statement that the bird is the nest's way of making another nest is as helpful as accounts couched in terms of genes' intentions. However, the language of intentions rests on different evidence and (...) assumptions from causal language and the languages are not interchangeable. Understanding ontogeny in causal terms requires explanations that are made as simple as possible but not so simple that they become completely unrealistic. (shrink)

At the beginning of the 1950s most students of animal behavior in Britain saw the instinct concept developed by Konrad Lorenz in the 1930s as the central theoretical construct of the new ethology. In the mid 1950s J.B.S. Haldane made substantial efforts to undermine Lorenz''s status as the founder of the new discipline, challenging his priority on key ethological concepts. Haldane was also critical of Lorenz''s sharp distinction between instinctive and learnt behavior. This was inconsistent with Haldane''s account of the (...) evolution of language, and, according to Haldane, inconsistent with elementary genetics. British attitudes to the instinct concept changed dramatically in the wake of Daniel S. Lehraman''s 1953 critique of Lorenz, and by the 1960s Lorenz drew a clear distinction between his own views and those of the English-speaking ethologists. The inconsistencies between Lorenz''s ideas and the trends in contemporary evolutionary genetics that are reflected in Haldane''s critiques may help to explain why the Lorenzian instinct concept was unable to maintain itself in Britian.

In the late 1930s networks of amateur observers across Britain were collecting data on birds , aircraft and society itself . This paper concentrates on birdwatching practice in the period 1930–1955. Through an examination of the construction of birdwatching's subjects, the Observers, and their objects, birds, it is argued that amateur strategies of scientific observation and record reflected, and were part-constitutive of, particular versions of ecological, national and social identity in this period. The paper examines how conflicts between a rural, (...) organicist Britishness and a modern, planner-preservationist Britishness were elaborated and contained within the figure of the birdwatcher and within the institutional epistemologies of the Royal Society for the Protection of Birds and the British Trust for Ornithology. Such conflicts are shown to be embedded in the structuring of visual perception in different strategies of bird and aircraft identification, particularly between analytic and gestalt methods; the paper examines, using the related ‘field-science’ of aircraft recognition, the importance of identificatory processes in the construction of the Observer, and concludes by examining whether tensions between organicist and scientific discourses were in any sense resolved by the end of this period.

Hugely controversial on publication, this is an insightful and characteristically entertaining survey of animal behaviour and the evolution of aggression throughout the animal world.

In the years leading up to the Second World War the ethologists Konrad Lorenz and Nikolaas Tinbergen, created the tradition of rigorous, Darwinian research on animal behavior that developed into modern behavioral ecology. At first glance, research on specifically human behavior seems to exhibit greater discontinuity that research on animal behavior in general. The 'human ethology' of the 1960s appears to have been replaced in the early 1970s by a new approach called ‘sociobiology’. Sociobiology in its turn appears to have (...) been replaced by an approach calling itself Evolutionary Psychology. Closer examination, however, reveals a great deal of continuity between these schools. At present, whilst Evolutionary Psychology is the most visible form of evolutionary psychology, empirical and theoretical research on the evolution of mind and behavior is marked by a diversity of ideas and approaches and it is far from clear which direction(s) the field will take in future.

Peculiar to Konrad Lorenz’s view of instinctive behavior is his strong innate-learned dichotomy. He claimed that there are neither ontogenetic nor phylogenetic transitions between instinctive and experience-based behavior components, thus contradicting all former accounts of instinct. The present study discusses how Lorenz came to hold this controversial position by examining the history of Lorenz’s early theoretical development in the crucial period from 1931 to 1937, taking relevant influences into account. Lorenz’s intellectual development is viewed as being guided by four theoretical (...) and practical commitments as to how to study and explain behavior. These four factors, which were part of the general approach of Lorenz but not of other animal psychologists, were crucial in bringing about his specific position on instinctive behavior. (shrink)

David Lack of Oxford University and V. C. Wynne- Edwards of Aberdeen University were renowned ornithologists with contrasting views of the modern synthesis which deeply influenced their interpretation and explanation of bird behavior. In the 1950's and 60's Lack became the chief advocate of neo-Darwinism with respect to avian ecology, while Wynne- Edwards developed his theory of group selection. Lack 's position was consistent with the developing focus on individual level adaptation, which was a core concept of the modern synthesis. (...) Alternatively, Wynne- Edwards viewed the emphasis on populations as the most important development provided by the modern synthesis. In this paper, I present the development of these two positions and trace their roots in the literature of the synthesis. Through an analysis of Lack 's 1966 critique of Wynne- Edwards I conclude that Wynne- Edwards was, in many ways, justified in his pursuit of group level explanations. (shrink)
