Zoology - Evolution Question with Solution | TestHub
Which of the following evidences does not favour the Lamarckian concept of inheritance of acquired characters?
Options:
Answer:
Solution:
Industrial melanism is an adaptation where the moths living in the industrial areas developed melanin pigments to match their body to the soot-covered surroundings. The phenomenon provides an excellent example of operation of selection in natural conditions. Industrial melanism, therefore, presents an excellent example of natural selection (proposed by Darwin), but it is not the example of acquired characters proposed by Lamarck. In caves, due to absence of light, the body of the animal lacks pigmentation, e.g., Proteus anguinus. In pythons and related snakes rudimentary pelvic girdle and traces of hindlimb are present. They form small clawed projections externally, but internally there are vestiges of an ilium, femur, tibia and a claw. In aquatic birds and flying frog, the feet are webbed which sustain it in the prolonged leaps to which it is adapted.
