Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the reason behind the extinction of the Abingdon tortoise in the Galapagos Islands.

2. **Identifying Key Concepts**: The extinction of a species can often be linked to competition for resources. The competitive exclusion principle states that two species competing for the same resources cannot coexist indefinitely if one is inferior to the other.

3. **Analyzing the Case of the Abingdon Tortoise**: The Abingdon tortoise was native to the Galapagos Islands. Its extinction can be attributed to the introduction of another species that competed for the same resources.

4. **Identifying the Competing Species**: In this case, the species that was introduced and led to the extinction of the Abingdon tortoise was the goat. Goats are known to be better browsers and more efficient at consuming the available vegetation.

5. **Conclusion**: Due to the introduction of goats, the Abingdon tortoise could not compete effectively for food resources, leading to its eventual extinction.

**Final Answer**: The Abingdon tortoise in the Galapagos Islands became extinct due to the introduction of goats.
