BIOL 1107 Chapter Notes - Chapter 40: Cataglyphis, Convergent Evolution, Cell Membrane
Document Summary
Chapter 40: basic principles of animal form and function. Ex. desert ant can live in high temps. Species vary in organization and appearance due to natural selection and adaptation. Body temp regulation, anatomy and physiology relating to animals interactions with environment. Animal form and function are correlated at all levels of organization. Size and shape of animal are fundamental aspects affect how animal interacts with environment. Body of animal is results of pattern of development by genome. Physical laws affect: limit range of animal forms. Water limits possibilities of shape for fast swimming animals. Water is 1,000 times denser than air. Seal, penguin and tuna fast swimmer. Convergent evolution: natural selection results in similar adaptations for diverse organisms with same environmental challenge. Ex. strong currents while swimming seals, penguin or tuna. Bodies increase in size muscles have to be larger fraction of total body mass. Body plan: basic features of animals genome.
