SOCIOBIOLOGY IN SUPPORT OF THE ECOLOGICAL CRISIS AND THE ENVIRONMENTAL EMERGENCY Giovanna Acampora, CNR – Institute of.

For example, Giraldeau describes deviations from optimality in the evolution of photopigments in the rods as opposed to cones in the retinas of fish that live in certain sorts of marine environments where a shift in photosensitivity would be useful; Giraldeau uses this deviation to suggest the presence of a molecular constraint on the evolution of the rod cells.

Presumably, repeated failures to find ways to fill in the gaps in these optimality models could ultimately result in the scientists concerned considering alternative, non-adaptationist explanations. So in order for the behavioral ecologists do this work they do not need to be committed to the strong view that natural selection is always the most important force in the origin of traits; this heuristic requires at most the view that natural selection usually locally optimizes i.

However, another way to understand how the behavioral ecologists are using optimality models, one that is not so often considered, is that they are interested in providing a functional description of the traits they are studying Kitcher, ; see also Bolduc and Cezilly, , for a similar view in terms of decision patterns rather than behavioral strategies.

In the jewel wasp case, the behavioral ecologists have observed the wasps lay different egg sex ratios on different occasions. The question is how to make sense of these different sex-ratio laying behaviors: the guess is that these different behaviors hang together somehow, as manifestations of a particular egg-sex-ratio adjusting strategy; and that having this particular strategy, this particular pattern of egg-sex-ratio laying behavior, does something for the female wasp when considered as a whole.

But why should a behavioral ecologist accept that any particular such a functional description is true? An optimality model can allow a behavioral ecologist to find and test such a functional description in two ways. First, an optimality model explicitly or implicitly includes a strategy set, which is a set of descriptions of possible behavioral strategies; the model picks out one of these strategy descriptions as the one that is maximally adaptive.

The hypothesis is that this description of the maximally adaptive strategy will be the correct description of what the wasp is doing. These predictions allow him to test if the description is correct — if these predictions are true, then on this view, Werren has confirmed that the description of the particular sex-ratio adjusting strategy derived from his model is the correct description of what the wasp is doing.

Second, the description of the strategy picked out by the model is not simply a description of it as a series of behavioral dispositions i. For example, in the jewel wasp case, the presence of other female competitors, flexibility in brood size, the capacity of sons to mate multiple times, the impossibility of migration of sons between pupae and so on, are features of the environment that determine whether any potential egg laying strategy of the jewel wasp is maximally adaptive, and a well confirmed optimality model can show how.

Consequently, contingent on obtaining the appropriate evidence that this is the correct model, the description of the strategy given by a successful model is implicitly or explicitly a functional description of the strategy—a description of how the behavior contributes to the fitness of the organism.

For a more detailed discussion of the role of optimality modeling in biology, see the entry on adaptationism.

Pop Sociobiology is so-called because it is a view about how to study human behavior described in a variety of literature written by Wilson and others[ 4 ] for a general, rather than an academic audience.

Genetic determinism. In a variety of articles major critics of sociobiology such as Stephen J. Gould similarly claims that sociobiologists do not realize that genes only produce traits with a contribution from the environment.

Both of these claims are believed, even by other critics, to be unfair analyses of the views of the sociobiologists, and especially Wilson—for example, Kitcher, one of the strongest critics of sociobiology, takes Gould and the SSG to task on this point Kitcher, , 22— In On Human Nature Wilson describes genes as, essentially, difference makers—he explicitly claims that differences in genes, even for heritable traits, only explain the variance in traits across a population; they are by no means independent causes for any trait in individuals and variation in the environment also accounts for part of the variation in any trait Wilson, , In at least one paper responding to the SSG Wilson says that, on the question of the relative contributions to the variation in human behavior from variation in genes vs.

Wilson also does seem to be trying to support his claim that there are some human behaviors which are probably highly heritable: he describes a variety of different sorts of evidence that might identify them.

This evidence includes cross cultural appearance e. Wilson, , ; Wilson, , 20, ; plausible homology with other closely related species especially chimpanzees e. Finally, Wilson claims that trying to change human behavior from its heritable form usually fails or causes misery Wilson, , 20 [ 6 ]; he describes the failures of certain attempts to change the features of normal human behavior by massively changing the social environment, such as the persistence of family ties under slavery Wilson, , and in the Israeli kibbutzim , Of course, whether or not all of the above is good evidence for his claims is very much up for debate Kitcher, ; Sociobiology Study Group of Science for the People, It is worth bearing in mind that while Wilson thinks the evidence that some human behaviors are heritable is overwhelming Wilson, , 19 he does see many of his specific proposed evolutionary explanations as preliminary and speculative rather than fully formed for example, Wilson is explicit that his discussion of homosexuality is preliminary: , For more discussion of the problems relating to heritability when studying the evolution of behavior, see section 4.

Ignoring learning and culture. As a concomitant of the objection that Pop Sociobiology was committed to genetic determinism, its central players are also often accused of being insensitive to the problem of learning and culture, i.

Furthermore, partly in response to these concerns on the part of his critics Wilson eventually went on to publish Genes, Minds and Culture with Charles Lumsden Lumsden and Wilson, , which was an attempt to consider the effects of cultural transmission on the nature and spread of behavioral traits, and of the interaction between genes and culture. The book, however, was subject to heavy criticism see, for example, Kitcher, ; Lewontin, ; Maynard Smith and Warren, Strong adaptationism. The third problematic feature ascribed to Pop Sociobiology was its reliance on an overly strong form of adaptationism.

Again, insofar as Wilson and the other sociobiologists are being purely speculative this criticism may be warranted: quite a lot of the evolutionary explanations of particular human behaviors Wilson describes in the first and last chapters of Sociobiology and in On Human Nature are speculation on his part although not entirely speculation.

Furthermore, while Wilson made no attempt to test any of his speculative hypotheses, behavioral ecologists do try to test adaptationist hypotheses about humans and other animals.

Again, the proper question is whether these tests are appropriate or sufficient to establish the truth of the hypotheses in question. Gould and Lewontin do, however, make some more sophisticated objections to adaptationist methods; some of these will be discussed in Section 4.

The different names tend to be used when the researchers concerned are emphasizing the connections of their field with anthropology or with non-human behavioral ecology. HBE has a great deal in common with the non-human behavioral ecology described above. In particular, it shares its focus on behavior, rather than the psychological mechanisms described in evolutionary psychology. Remember me Forgot Password?

The need to make searches that are within the boundaries between biological and social, socioniologia in so far as the transformation of the natural environment increasingly influence the mechanisms of socio-economic and spiritual development of society. The modelling of human phenomena is to represent the effects from human acting on the network of relationships between the human species, the species of animal, plant species and species abiotic; interactions are described in diachronic sense, since the species interact with each other influencing in a given moment and in synchronic sense, since interfere on its evolution.

The act of contemporary man must consider that the biological components and physical-chemical components contained in the Biosphere, in the Atmosphere, in the Hydrosphere and Lithosphere are dynamically linked, phenomenon that determines continuous processes of change in biological systems.The book, however, was subject to heavy criticism see, for example, Kitcher, ; Lewontin, ; Maynard Smith and Warren, Likewise, the police, the judiciary, law and policy-makers and the media need to have a greater understanding of the issues facing SIWs.

As a consequence, the human behavioral ecologists have to appeal to the fossil record in detail to determine what sorts of evolutionary transitions might have been involved Hawkes, ; Kaplan et al. Legal Restrictions Because of legal restrictions surrounding the industry, SIWs are frequently isolated and forced into work areas that can be very dangerous.
