Question

Which of the following facts developed suspicious in Lamarckism?

• A. Human females are not born with bored ear pinna although they have been bored for thousands of years.
• B. Giraffe has long neck to eat leaves of tall trees.
• C. A stag can run fast to protect against the enemies.
• D. None of the above.

Answer 1

The correct option is A Human females are not born with bored ear pinna although they have been bored for thousands of years.

Boring of pinna (external ear) and nose of Indian women is never inherited to the next generations although they have been bored for thousand of years, it is not explained by Lamarckism.

The ancestors of giraffe were bearing a small neck and fore­limbs and were like horses. But as they were living in places with no surface vegetation, they had to stretch their neck and forelimbs to take the leaves for food, which resulted in the slight elongation of these parts, it is explained by Lamarckism.

The ancestors of stag were not having so much speed in running, but as they needed protection from other animals of that time they started running, due to which present speed were achieved by the stag, it is explained by Lamarckism.

Therefore, the correct answer is option A.
