Document Summary
Evolutionary adaptations do not occur within an individual! Concept 22. 2: descent with modification by natural selection explains the adaptations of organisms and the unity and diversity of life: explain the mechanism for evolutionary change proposed by darwin in on the origin of. Inference 1: individuals whose inherited traits give them a higher probability of surviving and reproducing in a given environment leave more offspring than other individuals. There is little evidence that acquired traits can be inherited by their offspring. Side note two key points about natural selection: natural selection is a process of editing, not a creative mechanism. In the case of drug resistance a drug does not create resistant pathogens; it selects for resistant individuals that are already present in the population: natural selection depends on time and place. It favors those characteristics in a genetically variable population that provide advantage in the current, local environment.
