Which of the following cannot be explained by Lamarckism ?
A
Absence of lips in snakes
B
Long neck of giraffe
C
Degeneration of visual apparatus in cave dwellers
D
Dull progeny of noble laureate
(AIIMS-2012)
Solution
According to Lamarck, during the lifetime of an organism new characters are developed due to internal vital forces, effect of environment, new needs, use and disuse of organs. These acquired characters are inherited from one generation to another. According to him, intelligence should also be inherited and so it fails to explain dull progeny of nobel laureate.
