Document Summary
The science that explores the relationship between behavior, ecology, and evolution to elucidate the adaptive significance of animal actions. It occurs when the number or strength of synaptic connections between neurons is altered in response to stimuli. A behavior which, if adopted by a population in a given environment, cannot be invaded by any alternative behavioral strategy. If individual selection predominates then these alleles will __________; if group selection predominates these alleles will __________ disappear; spread. The safety in numbers that arises through swamping the foraging capacity of local predators. It occurs whenever a helping individual behaves in a way that benefits another individual at a cost to its own fitness. A type of social organization in which species have complete reproductive division of labor. In a eusocial group, many individuals never reprodue, instead hlep to rear offspring of a limited number of dominant individuals. A group of spatially separated populations of the same species that interact at some level.
