1. Which of the following statements best describes the theory of natural selection?

Answer: C

Explanation:

Organisms with favorable genetic traits have a greater chance of surviving and producing offspring.

Natural selection is best described by the principle that organisms possessing advantageous traits are more likely to survive and reproduce, thus passing those traits on to the next generation.

A) Organisms that are the strongest and largest live longer and reproduce more.

This statement oversimplifies the concept of natural selection by implying that only size and strength determine survival and reproductive success. Natural selection encompasses a broader range of traits, including adaptability to the environment and other genetic factors, not solely physical attributes.

B) Humans select the organisms that they find most beneficial and breed them.

This statement refers to artificial selection rather than natural selection. While humans can influence which organisms reproduce, natural selection occurs without human intervention and is based on environmental pressures that favor certain traits over others.

C) Organisms with favorable genetic traits have a greater chance of surviving and producing offspring.

This statement accurately reflects the core principle of natural selection. It emphasizes that genetic traits which enhance survival and reproductive success are favored in the process of evolution, leading to a greater prevalence of those traits in future generations.

D) Organisms that acquire beneficial traits during their lifetime pass them on to their offspring.

This statement is incorrect as it suggests the inheritance of acquired characteristics, which is not supported by modern genetics. Natural selection operates on genetic traits that are inherited rather than those that are acquired during an organism's lifetime.

Conclusion

Option C is the only statement that correctly encapsulates the theory of natural selection, highlighting the importance of favorable genetic traits in survival and reproduction. The other options either misinterpret the concept or refer to different forms of selection, ultimately failing to capture the essence of how natural selection operates in evolution.
