Evolutionary explanations of behavior are based on…
the principle that the environment presents challenges to individuals.
therefore, those who adapt best to their environment (the fittest) will have a greater chance of surviving and passing on their genes to offspring
Darwin’s Theory of Natural Selection
explains how species obtain adaptive characteristics to survive in an ever-changing environment. (evolving to meet environmental challenges)
3 behaviours humans and animals have in common
mate selection, maternal bonding with offspring, and self preservation.
evolutionary psychologists attempt to explain:
how certain behaviours are results to the development of our species over time
behaviours are genetic and may be inherited
intersexual selection
where members of one sex (usually females) choose members of the opposite sex
intrasexual selection
competition between members of the same sex (usually males) for access to mates
