Question

The animals of cold countries have relatively shorter and poorly developed ears, eyes, hairs and other phenotypic characters. This is known by which law?

• A. Cope’s Law
• B. Dollo’s Law
• C. Allen’s Law
• D. Bergmann's Law

Answer 1

The correct option is C

Allen’s Law

Allen’s law states that 'animals that live in very cold climates, their extremities such as ears, tails etc. become progressively smaller'. Cope’s law states that 'there is a tendency for animals to increase in size during the long course of evolution'. Dollo’s law states that 'evolution is irreversible'. Bergmann’s law states that 'warm-blooded animals become larger in the northern and colder parts of their range'.
