Evolution

Evolution is a change in the inherited characteristics of a population over time through natural selection. A population is a group of organisms of the same species living in an area. An individual does not evolve during its lifetime: the change is seen across generations as some inherited variants become more common.

Evolution means change in the inherited characteristics of a population over generations. Their explanation was natural selection: individuals differ, and those with inherited characteristics better suited to their environment are more likely to survive and reproduce. Their offspring can inherit those characteristics.

Evolution is a change in the inherited characteristics of a population over time, through natural selection. These changes occur across generations and may eventually result in the formation of new species.

The population’s inherited characteristics have changed: this is evolution by natural selection.
