characteristic that evolved in response to an organism's specific environment that increase an organism's chances of survival + reproduction
anatomical adaptation
structural or physical characteristics of an organism
e.g. breakdown of chemicals or sperm having mitochondria that provides ATP
behavioural adaptation
ways an organism behaves
e.g. courtship behaviour to mate for high chances of reproduction
physiological adaptation
biological processes within an organism
e.g. tiger stripes give camouflage advantage to get prey
convergent evolution
process whereby organisms that are not closely related independently evolve similar trait as a result of being adapted to same environment or ecological riches
