What natural selection causes changes in?
1 answer
Natural selection causes changes in the characteristics, or traits, of organisms over time. These changes occur because certain traits make the organism better equipped to survive and reproduce in their environment. This means that individuals with advantageous traits are more likely to pass on their genes to the next generation, while those with less advantageous traits are less likely to survive and reproduce. Over time, the frequency of certain traits in a population shifts, leading to the evolution of new species.
