Competition in natural selection definition
WebAn adaptation is a feature that arose and was favored by natural selection for its current function. Adaptations help an organism survive and/or reproduce in its current environment. Adaptations can take many forms: a behavior that allows better evasion of predators, a protein that functions better at body temperature, or an anatomical feature that allows Web1. be able to survive until reproductive age. 2. find and "acquire" a mate. 3. successfully reproduce offspring. natural selection operates by differences in relative fitness. 1. to be able to survive to reproductive age and beyond: → the longer an individual survives, the higher the chances to having more reproductive events. 2. finding a mate.
