How are the mammals from colder climate adapted to their surroundings?

Explanation

**Step-by-Step Solution:**

1. **Understanding Adaptation**:
- Adaptation refers to the characteristics that enable an organism to survive and reproduce in its environment. These adaptations can be morphological (physical structure), physiological (internal processes), or behavioral (actions taken by the organism).

2. **Morphological Adaptations**:
- Mammals in colder climates exhibit specific physical traits to help them survive. Notably, they tend to have shorter ears and limbs. This is a crucial adaptation because shorter extremities reduce the surface area of the body, which in turn minimizes heat loss. This principle is known as **Ellen's Rule**.
