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 is C
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.
