Sociobiology in Turmoil Again
GENERAL ARTICLES Sociobiology in turmoil again Raghavendra Gadagkar Altruism is defined as any behaviour that lowers the Darwinian fitness of the actor while increasing that of the recipient. Such altruism (especially in the form of lifetime sterility exhibited by sterile workers in eusocial insects such as ants, bees, wasps and termites) has long been considered a major difficulty for the theory of natural selection. In the 1960s W. D. Hamilton potentially solved this problem by defining a new measure of fitness that he called inclusive fitness, which also included the effect of an individual’s action on the fitness of genetic relatives. This has come to be known as inclusive fitness theory, Hamilton’s rule or kin selection. E. O. Wilson almost single-handedly popularized this new approach in the 1970s and thus helped create a large body of new empirical research and a large community of behavioural ecologists and kin selectionists. Adding thrill and drama to our otherwise sombre lives, Wilson is now leading a frontal attack on Hamilton’s approach, claiming that the inclusive fitness theory is not as mathematically general as the standard natural selection theory, has led to no additional biological insights and should therefore be aban- doned. The world cannot but sit up and take notice. Keywords: Altruism, eusociality, Hamilton’s rule, inclusive fitness theory, kin selection, sociobiology. THE science of sociobiology is in turmoil again and this Altruism and eusociality time on theoretical grounds. And yes, E. O. Wilson (of Harvard University) is at the epicentre of it; but, believe Among the various kinds of social interactions seen it or not, this time around he is leading the attack and his commonly in group-living species, the most paradoxical followers (erstwhile?) are at the receiving end. -

"PRINCIPLES OF PHYLOGENETICS: ECOLOGY AND EVOLUTION" Integrative Biology 200 Spring 2016 University of California, Berkeley D.D. Ackerly March 7, 2016. Phylogenetics and Adaptation What is to be explained? • What is the evolutionary history of trait x that we see in a lineage (homology) or multiple lineages (homoplasy) - adaptations as states • Is natural selection the primary evolutionary process leading to the ‘fit’ of organisms to their environment? • Why are some traits more prevalent (occur in more species): number of origins vs. trait- dependent diversification rates (speciation – extinction) Some high points in the history of the adaptation debate: 1950s • Modern Synthesis of Genetics (Dobzhansky), Paleontology (Simpson) and Systematics (Mayr, Grant) 1960s • Rise of evolutionary ecology – synthesis of ecology with strong adaptationism via optimality theory, with little to no history; leads to Sociobiology in the 70s • Appearance of cladistics (Hennig) 1972 • Eldredge and Gould – punctuated equilibrium – argue that Modern Synthesis can’t explain pervasive observation of stasis in fossil record; Gould focuses on development and constraint as explanations, Eldredge more on ecology and importance of migration to minimize selective pressure 1979 • Gould and Lewontin – Spandrels – general critique of adaptationist program and call for rigorous hypothesis testing of alternatives for the ‘fit’ between organism and environment 1980’s • Debate on whether macroevolution can be explained by microevolutionary processes • Comparative methods -

Mishler, Dept. of Integrative Biology 2-6810, [email protected] Evolution lecture #6 -- Tempo and Mode in Macroevolution -- Nov. 14th, 2008 Reading: pp. 521-531 (ch. 25) 8th ed. pp. 480-488 (ch. 24) 7th ed. • Summary of topics • Define and contrast adaptation and exaptation • Give examples of how adaptive radiations lead to diversity within an evolutionary lineage • Give examples of how convergent evolution shows the action of selection on organisms that are not closely related but have a shared way of life • Contrast punctuated equilibria and gradualism • Describe the features of developmental changes that can lead to evolution ("evo-devo") • Define macroevolution • Adaptation Adaptation: Based on the observation that organism matches environment closely. Darwin & many Darwinians thought that all structures must be adaptive for something. But, this has come under severe challenge in recent years. Not all structures and functions are adaptive. Some matches between organism and environment are accidental, or the causality is reverse (i.e., the structure came first, function much later). • By definition, an adaptation in a formal sense requires fulfillment of four different tests: Engineering. Structure must indeed function in hypothesized sense. Heritability. Differences between organisms must be passed on to offspring. Natural Selection. Difference in fitness must occur because of differences in the hypothesized adaptation. Phylogeny. Hypothesized adaptive state must have evolved in the context of the hypothesized cause. Think in terms of problem (e.g., environmental change) and solution (adaptation). Requires correct phylogenetic polarity (i.e., correct sequence of events on a cladogram). -
Exaptation, Grammaticalization, and Reanalysis
Heiko Narrog Tohoku University Exaptation, Grammaticalization, and Reanalysis Abstract The goal of this paper is to argue that exaptation, as introduced into the study of language change by Lass (1990, 1997), in specific functional domains, is a limited alternative to grammaticalization. Exaptation, similarly to grammaticalization, leads to the formation of grammatical elements. Like grammaticalization, exaptation is based on the mechanism of reanalysis. It decisively differs from grammaticalization, however, as it implies change in the opposite direction, namely from material absorbed in the lexicon back to grammatical material. Two sets of data are presented as evidence for the replicability of this process. One involves the occurrence of exaptation across languages in a specific semantic domain, namely, the evolution of morphological causatives out of lexical verb patterns. The other data pertain to recurrent processes of exaptation in one language, namely in Japanese, where exaptation figures in the development of various morphological categories. In all cases of exaptation, reanalysis is crucially involved. This serves to show that reanalysis may be more fundamental to grammatical change than both grammaticalization and exaptation. Furthermore, it allows for change both with the usual directionality of grammaticalization and against it. 1. Introduction Even detractors of grammaticalization theory do not seriously challenge the fact that in the majority of cases the morphosyntactic and semantic development of grammatical material follows the paths outlined in the standard literature on grammaticalization. The two following California Linguistic Notes Volume XXXII No. 1 Winter, 2007 2 issues, however, potentially pose a critical challenge to the validity of the theory. First, there is the question of the theoretical status of grammaticalization as a coherent and unique concept. -

Exaptation, Adaptation, and Evolutionary Psychology
Exaptation, Adaptation, and Evolutionary Psychology Armin Schulz Department of Philosophy, Logic, and Scientific Method London School of Economics and Political Science Houghton St London WC2A 2AE UK [email protected] (0044) 753-105-3158 Abstract One of the most well known methodological criticisms of evolutionary psychology is Gould’s claim that the program pays too much attention to adaptations, and not enough to exaptations. Almost as well known is the standard rebuttal of that criticism: namely, that the study of exaptations in fact depends on the study of adaptations. However, as I try to show in this paper, it is premature to think that this is where this debate ends. First, the notion of exaptation that is commonly used in this debate is different from the one that Gould and Vrba originally defined. Noting this is particularly important, since, second, the standard reply to Gould’s criticism only works if the criticism is framed in terms of the former notion of exaptation, and not the latter. However, third, this ultimately does not change the outcome of the debate much, as evolutionary psychologists can respond to the revamped criticism of their program by claiming that the original notion of exaptation is theoretically and empirically uninteresting. By discussing these issues further, I also seek to determine, more generally, which ways of approaching the adaptationism debate in evolutionary biology are useful, and which not. Exaptation, Adaptation, and Evolutionary Psychology Exaptation, Adaptation, and Evolutionary Psychology I. Introduction From a methodological point of view, one of the most well known accusations of evolutionary psychology – the research program emphasising the importance of appealing to evolutionary considerations in the study of the mind – is the claim that it is overly “adaptationist” (for versions of this accusation, see e.g. -
