Q.9
After the industrial revolution, melanic moths survived because ...
0%
a) They had black colour
0%
b) They had grey body colour
0%
c) They shifted to different habitat
0%
d) They reproduced vigorously
Explanation
The Peppered Moth occurs in two main colour forms, one pale with black speckles, the other solid black. Before the early 1800’s the black forms were rare, but over the next century they gradually increased in numbers, especially in regions surrounding rapidly industrialising cities like Manchester. At the same time the number of light forms decreased. This increase in numbers of black moths was called “industrial melanism,” and has been presented to generations of biology students as a classic example of natural selection, and therefore evolution, since according to Darwin, natural selection produces evolution. Answer : (a)

Explanation
Adaptive radiation is an evolutionary pattern whereby a single ancestral form (or species) diversifies (or speciates) into several or many related forms (or species). According to this concept, the different descendant taxa are similar, but each is adapted for a particular environmental niche. It is held that adaptive radiation led to the presence of over 250,000 species of beetles, Answer : (a)
