Question

Which of the following evidence does not favor the Lamarckian concept of inheritance of acquired characters?
a. Absence of limbs in snakes
b. Melanisation in the peppered moth
c. Presence of webbed toes in aquatic birds
d. Lack of pigment in cave-dwelling animals

Answer 1

Hint: "Neo-Lamarckism" is the other name for a Lamarckian inheritance, generally it is the notion that an organism can essentially pass on to its offspring bodily traits that the discern organism received through use or disuse at some point of its lifetime, or so that they essentially even though.

Complete answer:
Moths living in the industrial regions have industrial melanism, this melanism especially an adaptation. Melanin pigments are evolved literally to shape their frame to the soot included surroundings in a usually foremost manner. The phenomenon provides an incredible example of the operation of choice in the type of herbal conditions in a diffuse manner. Business melanism, therefore, specially offers an exceptional instance of actually natural selection, but it simply isn't the example of obtained characters proposed through Lamarck, or so that they are generally of notion.

In caves, basically because of the absence of mild, the body of the common animal lacks pigmentation, which for the most component is quite substantial. They form small-clawed projections externally, but internally there normally are vestiges of an ilium, femur, tibia, and a claw, virtually similarly showing how in caves, usually because of the absence of mild, the body of the genuinely animal lacks pigmentation in a certainly massive way.

Hence, the correct answer is option (B).

Note: Peppered moths seem as mild and essentially dark pretty colored moths, which simply is reasonably widespread. While the pupae were fed in particular leaves covered with coal soot the wings of the adults which are especially darker in an in particular massive manner. For experiments, few scientists for all intents and functions have breed and functions peppered moths, predominantly. They go mild and commonly dark moths in a totally large manner.
