Evolutionary physiology

Last updated
Natural and sexual selection are often presumed to act most directly on behavior (e.g., what an animal chooses to do when confronted by a predator), which is expressed within limits set by whole-organism performance abilities (e.g., how fast it can run) that are determined by subordinate traits (e.g., muscle fiber-type composition). A weakness of this conceptual and operational model is the absence of an explicit recognition of the place of life history traits. Phenotypic Hierarchy 1.svg

A weakness of this conceptual and operational model is the absence of an explicit recognition of the place of life history traits.

Evolutionary physiology is the study of the biological evolution of physiological structures and processes; that is, the manner in which the functional characteristics of organisms have responded to natural selection or sexual selection or changed by random genetic drift across multiple generations during the history of a population or species. [2] [3] It is a sub-discipline of both physiology and evolutionary biology. Practitioners in the field come from a variety of backgrounds, including physiology, evolutionary biology, ecology, and genetics.

Contents

Accordingly, the range of phenotypes studied by evolutionary physiologists is broad, including life history traits, behavior, whole-organism performance, [4] [5] functional morphology, biomechanics, anatomy, classical physiology, endocrinology, biochemistry, and molecular evolution. The field is closely related to comparative physiology, ecophysiology, and environmental physiology, and its findings are a major concern of evolutionary medicine. One definition that has been offered is "the study of the physiological basis of fitness, namely, correlated evolution (including constraints and trade-offs) of physiological form and function associated with the environment, diet, homeostasis, energy management, longevity, and mortality and life history characteristics". [6]

History

The origins of evolutionary physiology can be traced to early 20th-century Russian biology. In 1914, zoologist A. N. Severtsov published work on the evolutionary morphology of organ systems, linking physiological function with adaptive evolution. [7] Severtsov and his students developed a Soviet tradition of integrating physiology, morphology, and evolutionary theory, which influenced later studies of adaptation in both plants and animals. [8] As the name implies, evolutionary physiology is the product of a merger between two distinct scientific disciplines. According to Garland and Carter, [3] evolutionary physiology arose in the late 1970s, following debates concerning the metabolic and thermoregulatory status of dinosaurs (see physiology of dinosaurs) and mammal-like reptiles.

This period was followed by attempts in the early 1980s to integrate quantitative genetics into evolutionary biology, which had spillover effects on other fields, such as behavioral ecology and ecophysiology. In the mid- to late 1980s, phylogenetic comparative methods started to become popular in many fields, including physiological ecology and comparative physiology. A 1987 volume titled New Directions in Ecological Physiology [9] had little ecology [10] but a considerable emphasis on evolutionary topics. It generated vigorous debate, and within a few years the National Science Foundation had developed a panel titled Ecological and Evolutionary Physiology.

Shortly thereafter, selection experiments and experimental evolution became increasingly common in evolutionary physiology. Macrophysiology has emerged as a sub-discipline, in which practitioners attempt to identify large-scale patterns in physiological traits (e.g. patterns of co-variation with latitude) and their ecological implications. [11] [12] [13]

More recently, the importance of evolutionary physiology has been argued from the perspective of functional analyses, epigenetics, and an extended evolutionary synthesis. [14] The growth of evolutionary physiology is also reflected in the emergence of sub-disciplines, such as evolutionary biomechanics [15] [16] and evolutionary endocrinology, [17] [18] which addresses such hybrid questions as "What are the most common endocrine mechanisms that respond to selection on behavior or life-history traits?" [19]

Emergent properties

As a hybrid scientific discipline, evolutionary physiology provides some unique perspectives. For example, an understanding of physiological mechanisms can help in determining whether a particular pattern of phenotypic variation or co-variation (such as an allometric relationship) represents what could possibly exist or just what selection has allowed. [3] [20] [21] Similarly, a thorough knowledge of physiological mechanisms can greatly enhance understanding of possible reasons for evolutionary correlations and constraints than is possible for many of the traits typically studied by evolutionary biologists (such as morphology).
