Document Summary
Phenotype of an animal influences its reproductive success: include 3 important phenotypes: Stability: positive feedback loops: generate an explosive response b. i. Process of change in response to a controlled c. i. Physical or behavioral changes to the environment c. iii. Usually a lab setting: acclimatization: environmental variation. Process of change in response to a natural. Reductionism: learn about a system by studying the function of its parts: emergence: whole is often more than the sum of its parts. August krogh principle: for every biological problem there is an organism on which it can be most conveniently studied: incorporates the use of model organisms . Understanding a process in the model provides insight on how it works in other organisms. Scaling: isometric: morphology or physiology change in direct proportion to body mass, allometric: morphology or physiology change in disproportionately to body size increases. Proximate cause: immediate physiological or biochemical basis of its trait. Ultimate cause: evolutionary implications to a trait.
