Document Summary
18th century: bodily functions are a combination of both physical and chemical processes. Scholander (1905-1980): first and most influential comparative physiologist. Schmidt-nielsen (1915-2007): how animals live in extreme environments. George bartholomew (1923-2006): founder of the field of ecological physiology. Scholander find different systems in natural world to understand concepts. Schmidt- nielsen worked with camels look at animals for extreme environments look at the limitations of physiological processes. Barth variation in physiology is the driving force for evolution (selection process for speciation) Enviro physio depending on the difference in enviro and how that challenges the physiology of the organism. Evolutionary birds example in the same environment. Any differences in physiology will give an idea of the types of challenges faced evolution-wise. Unifying themes in physiology (table 1. 1: physiological processes obey the laws of chemistry and physics. Chemical laws govern interactions between biological molecules; e. g. weak bonds are sensitive to temperature; physiology is temperature-dependent.
