Development And Evolution

The problem of the repeated parts of organisms was at the center of the biological sciences as early as the first decades of the 19th century. Some concepts and theories (e.g., serial homology, unity of plan, or colonial theory) introduced in order to explain the similarity as well as the differences between the repeated structures of an organism were reused throughout the 19th and the 20th century, in spite of the fundamental changes during this long period that saw the diffusion of the evolutionary theory, the rise of experimental approaches, and the emergence of new fields and disciplines. Interestingly, this conceptual heritage was at the core of any attempt to unify the problems of inheritance, development, and evolution, in particular in the last decades, with the rise of “evo-devo.” This chapter examines the conditions of this theoretical continuity and the challenges it brings out for the current evolutionary sciences.

Evo Devo

Many researchers have argued that evolutionary developmental biology (evo-devo) constitutes a challenge to standard evolutionary theory, requiring the explicit inclusion of developmental processes that generate variation and attention to organismal form (rather than adaptive function). An analysis of these developmental-form challenges indicates that the primary concern is not the inclusion of specific content but the epistemic organization or structure of evolutionary theory. Proponents of developmental-form challenges favor moving their considerations to a more central location in evolutionary theorizing, in part because of a commitment to the value of mechanistic explanation. This chapter argues there are multiple legitimate structures for evolutionary theory, instead of a single, overarching or canonical organization, and different theory presentations can be understood as idealizations that serve different investigative and explanatory goals in evolutionary inquiry.

Freedom Of Action

Predicting the future accurately is at best difficult: general trends are often self-evident, specific predictions are often wrong. In the next 25 years in vertebrate physiology and biochemistry I anticipate an increase in the importance of multidisciplinary group approaches, with such groups working on problems of a broad integrative nature. I think that physiology and biochemistry will play a larger role in contributing answers to many of the controversial issues in general biology, for example, enlarging the functional base for evolutionary theory. I think that the administration of science in general is becoming more rigid and research directives more centralized, resulting in less freedom of action for individual scientists in Canada. Vertebrate physiology and biochemistry, however, continue to be very active and will continue to be so over the next 25 years.

Sources Of Contamination

The present research utilized evolutionary theory to examine the relation between the behavioral immune system (i.e., disgust sensitivity) and attitudes about vaccines. The findings from the studies suggest that higher levels of dispositional disgust sensitivity is predictive of more negative attitudes toward vaccines. These findings are consistent with several recent publications and thus have broad implications for public health research associated with vaccines. In Study 1, participants reporting higher dispositional disgust sensitivity (specifically, contamination disgust) tended to report more negative attitudes about vaccines. Study 2 replicated this result in a nonstudent sample using additional measures of disgust sensitivity more closely associated with aversion to perceived sources of contamination. Study 2 also revealed that beliefs about the likelihood of contracting illness in the future were unrelated to vaccine attitudes. Implications for the observed relation between intuitive aversion to contamination and vaccine attitudes are discussed.
