Which statement is accurate about evolution?

• A. Evolution is a process that leads to changes in the genetic makeup of populations over time.
• B. Evolution is a theory that has been completely disproven by modern science.
• C. Evolution occurs when individuals adapt during their lifetime to environmental changes.
• D. Evolution only occurs in large populations and not in small ones.

Answer: (A)

Verified step by step guidance

1. Understand that evolution is a fundamental concept in biology that explains how species change over time through variations in their genetic makeup.
2. Recognize that evolution is supported by extensive scientific evidence and is considered a well-substantiated scientific theory, not disproven by modern science.
3. Clarify that evolution occurs at the population level, not at the individual level. Individuals do not evolve; rather, populations evolve over generations.
4. Acknowledge that evolution can occur in both large and small populations, although the mechanisms and effects might differ due to genetic drift and other factors.
5. Conclude that the accurate statement about evolution is that it is a process leading to changes in the genetic makeup of populations over time.
