Question

Lamrck's theory of evolution fails to explain

• A. Indian women have been getting their ears pierced for thousands of years, but not a single baby with pierced ears is born.
• B. Giraffes have long necks because they have to eat leaves from the tall trees on their habitat.
• C. Deer have the capacity to escape from agile enemies because these can run very fast.
• D. High attitude pines have branches which slope down so that snow fails to collect them in winter.

Answer 1

The correct option is A Indian women have been getting their ears pierced for thousands of years, but not a single baby with pierced ears is born.

Indian women have getting their ears pierced for thousands of years, but this character does not passed to any offspring, this casts doubt on lamarck's theory of evolution. Later on, in Neo-lamarckism it was explained that only those characters will be inherited which can affect germ cells, while characters that affect somatic cells do not pass to descendants. Thus, the correct answer is 'Indian women have been getting their ears pierced for thousands of years, but not a single baby with pierced ears is born.'
