Biology Question on evolution
According to Darwin, the organic evolution is due to :
A
Reduced feeding efficiency in one species due to the presence of interfering species
B
Intraspecific competition
C
Interspecific competition
D
Competition within closely related species
Answer
Interspecific competition
Explanation
Solution
Darwin stated that, the organic evolution is due to interspecific competition. It is the competition between members of different species. Intraspecific competition occurs amongst members of the same species for obtaining optimum amounts of their food, shelter, mate, water, light, etc. Closely related species if compete cannot cause evolution. Reduced feeding efficiency in one species due to the presence of interfering species is due to strugle for existence.
