According to Darwin, the organic evolution is due to

Options

  1. Aintraspecific competition
  2. Binterspecific competition
  3. Ccompetition within closely related species
  4. Dreduced feeding efficiency in one species due to the presence of interfering species

Correct answer

B. interspecific competition

Step-by-step 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.
