According of Darwin, the organic evolution is due to

A

intraspecific competition

B

interspecific conpetition

C

competition within closely related species

D

reduced feeding efficiency in one species due to the presence of interfering species

Text Solution

Verified by Experts

The correct Answer is:
B
Darwin stated that the organic evolution is due to the 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 the struggle for existence.
