This indicates that the function of thyroxin is same in all animals. Evolutionary physiology is the study of the biological evolution of physiological structures and processes; that is, the manner in which the functional characteristics of individuals in a population of organisms have responded to natural selection across multiple generations during the history of the population. However, isolated groups of populations in nature tend to harbor both genetic and physiological divergence due to multiple selective pressures that they have encountered. Let's think about elephants. Adaptation via natural selection is an important driver of evolution, and repeatable adaptations of replicate populations, under conditions of a constant environment, have been extensively reported. This is to recapitulate the excretory materials of their ancestors, fishes, amphibians and reptiles serially before excreting urea. Here, we discuss the implications of considering physiological regulatory networks (PRNs) as integrated wholes, a perspective that reveals novel roles for physiology in organismal ecology and evolution. The organs and organ systems are similar in the closely related animals. The absence of this muscle in about 15 percent of humans is an example of how evolution is an ongoing process. When Charles Darwin sailed to the Galapagos and observed the many animals there, one species he noticed were the finches. Echolocation in bats is an adaptation for catching insects.
