Question

Quizplus · Accepted Answer

Evolution refers to changes in the genetic makeup of populations of organisms over time. While cells and organs within an organism may undergo changes, these do not necessarily constitute evolution unless they result in changes in the overall population over time. Fossils reflect past evolutionary changes, but they are not the same thing as evolution itself. The same is true of future organisms within the biosphere - while they may undergo genetic changes, evolution refers to the broader pattern of change across populations over time.
