by promoting detrimental genes by stimulating beneficial DNA mutations by preventing the introduction of other predator species by increasing the reproductive success of healthy prey animals
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: Wolves have adapted skills for hunting large hoofed animals such as elk, deer, or moose. Wolves tend to target prey animals that are sick or weak. The wolf benefits from this strategy because it uses less energy to hunt. How would the prey animal population also benefit from this strategy?
Possibilities:
- by promoting detrimental genes
- by stimulating beneficial DNA mutations
- by preventing the introduction of other predator species
- by increasing the reproductive success of healthy prey animals
