DARWIN’S THEORY OF NATURAL SELECTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During the Industrial Revolution in Britain, many new factories were built which released dark clouds of smoke into the air. Dark grey moths survived attacks by birds more often than their light grey neighbors. Over time, light grey moths disappeared from the area. This change in population is an example of:
A
Selective breeding
B
Natural selection
C
Genetic engineering
D
Cloning
Explanation: 

Detailed explanation-1: -Ostriches, emus, cassowaries, rheas, and kiwis can’t fly. Unlike most birds, their flat breastbones lack the keel that anchors the strong pectoral muscles required for flight.

Detailed explanation-2: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-3: -Individuals with adaptive traits-traits that give them some advantage-are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population.

Detailed explanation-4: -Which statement best explains why Darwin avoided discussing human beings in Origins? He was afraid of the response he would get from religious groups.
