Evolution is the process that allows living things to change over time.

• A. Evolution
• B. Photosynthesis
• C. Migration
• D. Reproduction

Answer: (A)

Evolution is the process by which populations change over generations as genetic variation is acted upon by forces like natural selection, mutation, gene flow, and genetic drift. This is exactly what allows living things to change over time, shaping traits and leading to new species. The other terms describe specific concepts: photosynthesis is how some organisms convert light into chemical energy; migration is the movement of individuals between populations; reproduction is the act of producing offspring. While these influence how genes spread or are expressed, they do not themselves define the long-term, population-wide change that evolution explains.
