- Animals require food for survival
- Hunting is a kind of method for obtaining food
- So, some animals must hunt to survive

- Some animals must hunt to survive
- Hunting requires sensing prey
- Hence, some animals must sense prey to survive

- If a living thing must do something to survive, then doing that something better has a positive impact on that living thing's survival
- An animal is a kind of living thing
- Therefore, if an animal must do something to survive, then doing that something better has a positive impact on that animal's survival

- Some animals must sense prey to survive
- If an animal must do something to survive, then doing that something better has a positive impact on that animal's survival
- Therefore, better senses have a positive impact on an animal 's survival

- Better senses have a positive impact on an animal 's survival
- Hearing is used for sensing sound by animals
- Therefore, better hearing has a positive impact on an animal's survival

- Inheriting is when an inherited characteristic is passed from parent to offspring by genetics / dna
- Senses are passed down from parent to offspring
- Hence, senses are an inherited characteristic

- Senses are an inherited characteristic
- Hearing is used for sensing sound by animals
- So, hearing is an inherited characteristic

- Better hearing has a positive impact on an animal's survival
- Hearing is an inherited characteristic
- So, better hearing is an inherited characteristic that has a positive impact on an animal's survival

- As the ability of a living thing to survive / to reproduce increases , the likelihood of passing on its traits to its decendents will increase
- Animals with traits that positively impact their survival have a greater ability to survive / reproduce
- Therefore, the decendants of an animal with traits that positively impacted their survival will also have traits that positivley impact their survival

- Better hearing is an inherited characteristic that has a positive impact on an animal's survival
- The decendants of an animal with traits that positively impacted their survival will also have traits that positivley impact their survival
- So, the decendants of an animal with better hearing will also have better hearing

Hence, the decendants of an animal with better hearing will also have better hearing
Question
A fox gave birth to an offspring that had a better sense of hearing than most foxes. How could this small change most likely result in descendants that are different from the original fox?
