Evolutionary physiology

Evolutionary physiology

Evolutionary physiology is the study of physiological evolution, which is to say, the manner in which the functional characteristics of individuals in a population of organisms have responded to selection across multiple generations during the history of the population.cite journal|last=Garland|first=T., Jr.|coauthors=and P. A. Carter|year=1994|title=Evolutionary physiology| url=http://www.biology.ucr.edu/people/faculty/Garland/GarlCa94.pdf|journal=Annual Review of Physiology|issn=|volume=56|issue=|pages=579–621|doi=10.1146/annurev.ph.56.030194.003051] It is a subdiscipline of both physiology and evolutionary biology. Practitioners in this field come from a variety of backgrounds, including physiology, evolutionary biology, ecology and genetics. Accordingly, the range of phenotypes studied by evolutionary physiologists is broad, including but not limited to life history, behavior, whole-organism performance, functional morphology, biomechanics, anatomy, classical physiology, endocrinology, biochemistry, and molecular evolution. It is closely related to comparative physiology and environmental physiology.

History

As the name implies, evolutionary physiology is the product of what was at one time two distinct scientific disciplines. According to Garland and Carter, evolutionary physiology arose in the late 1970s, following "heated" 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 spill-over effects on other fields, such as behavioral ecology and ecophysiology. In the mid- to late-1980s, phylogenetic comparative methods started to became popular in many fields, including physiological ecology and comparative physiology. An 1987 volume titled "New Directions in Ecological Physiology" [cite book|last=Feder|first=M. E.|coauthors=A. F. Bennett, W. W. Burggren, and R. B. Huey, eds.|authorlink=|title=New directions in ecological physiology|edition=|publisher=Cambridge Univ. Press|location=New York|year=1987|isbn=0521349389|pages=364 pp] had little ecology 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 [http://www.nsf.gov/pubs/progdesc/1998/bio/ibn/1148.htm Ecological and Evolutionary Physiology] . Shortly thereafter, selection experiments and experimental evolution became increasingly common in evolutionary physiology.

Emergent Properties of Evolutionary Physiology

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 covariation (such as an allometric relationship) represents what could possibly exist or just what selection has allowed. 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).

Areas of Research

Important areas of current research include:
* Organismal performance as a central phenotype
* Role of behavior in physiological evolution
* Physiological and endocrinological basis of variaiton in life history traits (e.g., clutch size)
* Functional significance of molecular evolution
* Extent to which species differences are adaptive
* Physiological underpinnings of limits to geographic ranges
* Role of sexual selection in shaping physiological evolution
* Magnitude of "phylogenetic signal" in physiological traits
* Role of pathogens and parasites in physiological evolution and immunity
* Application of optimality modeling to elucidate the degree of adaptation
* Role of phenotypic plasticity in accounting for species differences
* Mechanistic basis of trade-offs and constraints on evolution
* Origin of allometric scaling relations or allometric laws (and the so-called metabolic theory of ecology)
* Individual variation (see also Individual differences psychology)
* Functional significance of biochemical polymorphisms
* Analysis of physiological variation via quantitative genetics
* Paleophysiology and the evolution of endothermy
* Human adaptational physiology
* Darwinian medicine
