Which of the following is most affected by natural selection?

How does natural selection contribute to the evolution of organisms?

Explanation:

Natural selection is the process by which organisms with favorable traits are more likely to survive and reproduce, passing those traits on to their offspring. It is a key mechanism of evolution, driving the adaptation of species to their environment over time.

Natural selection is a fundamental concept in biology that explains how species evolve over time. It is based on the idea that individuals with advantageous traits are more likely to survive and reproduce, while those with less favorable traits are less likely to pass on their genes. This results in a gradual change in the characteristics of a population, leading to the emergence of new species.

In the case of the influenza virus, natural selection plays a significant role in the evolution of new strains. The virus evolves rapidly, leading to the emergence of different strains that can evade the immune system and cause widespread outbreaks. This process of evolution through natural selection is most evident during annual flu seasons when new strains of the virus become dominant.

Overall, natural selection drives the diversity of life on Earth by promoting the survival of organisms with traits that are well-suited to their environment. It is a continuous process that shapes the characteristics of populations and ultimately leads to the evolution of new species.
