Question

Bell and collaborators painstakingly documented a population of fossil sticklebacks from an ancient freshwater lake over a 20,000-year period. The prevalence of sticklebacks with full and reduced pelvises changed over time. Which is true?

Answer 1

Answer:

the answer is correct since species undergo evolutionary changes over time

Explanation:

These evolutionary changes are due to the fact that there could be modifications in the environment of living organisms, that is, in the water, which leads to different populations over time.
