ANSWERS WITH COMPLETE SOLUTIONS VERIFIED LATEST
UPDATE
behavioral ecology
the study of the ecological and evolutionary basis for animal behavior
proximate causation
"how" a behavior occurs or is modified
ultimate causation
"why" a behavior occurs in the context of natural selection
Fixed action pattern
a sequence of unlearned acts directly linked to a simple stimulus; essentially unchangeable
sign stimulus
External sensory stimulus that triggers a fixed action pattern.
Signal
a stimulus transmitted from one animal to another
Essential outcomes to animal behavior
, 1. Acquire nutrients
2. Maintain homeostasis
3. Reproduce
Pheromones
A small molecule released into the environment that functions in communication between members of
the same species. in animals it acts like a hormone
innate behavior
Animal behavior that is developmentally fixed and under strong genetic control. Innate behavior is
exhibited in virtually the same form by all individuals in a population despite internal and external
environmental differences during development and throughout their lifetimes.
cross-fostering study
A behavioral study in which the young of one species are placed in the care of adults from another
species.
twin study
A behavioral study in which researchers compare the behavior of identical twins raised apart with that of
identical twins raised in the same household.
Learning
The modification of behavior as a result of specific experiences
Challenge learning poses in reserach
Difficult to determine the contributions of nature or nurture in shaping learning or behavior
