Solution
| Basis of Difference | Evolution | Variation |
|---|---|---|
| Meaning | Evolution is the gradual change in populations over many generations, sometimes leading to the formation of new species. | Variation refers to differences in characteristics among individuals of the same species. |
| Scale | Evolution occurs across generations and affects populations over long periods. | Variation is observed among individuals within a population at a particular time. |
| Role | Evolution can result from the accumulation of inherited variations over many generations. | Variations provide differences that may help some individuals survive and reproduce more successfully. |
| Example | The changing proportions of light- and dark-coloured peppered moths across generations illustrate evolutionary change. | The differences in colour between light- and dark-coloured peppered moths are variations. |
