The "real" reason something occurred. A group of populations that are separated by space but consist of the same species. These separated populations interact as individual members. Actual reproductive rate of organism or population, measured by the number of gametes (eggs), seed set, or asexual reproductive structures An event which is closest to, or immediately responsible for causing, some observed result. An instinct of an organisms to behave a certain way High fecundity, small body size, unstable environment, dependant offspring, short life cycle, early maturity - small, reproduce fast, plants, bacteria, insects Stable environment, large body size, high parental care, mammals, humans Acquisition of knowledge that leads an organism to act a certain way.
