Which of the following is an evolutionary trend commonly observed in organisms?
- A. Decreased complexity over time
- B. Increased dependence on external resources
- C. Increased genetic diversity within populations
- D. Decreased adaptation to the environment
Correct Answer: C. Increased genetic diversity within populations
Explanation
Evolutionary trends generally involve changes that occur over time in a population or species. One commonly observed trend is an increase in genetic diversity within populations. Genetic diversity refers to the variety of genetic traits and variations present within a population. Increased genetic diversity can provide a population with a greater potential to adapt to changes in the environment, as it provides a wider range of genetic material for natural selection to act upon.
