Evolution question

2013 · Q71

NEETBiologyEvolutionMCQ+4 / −1
According to Darwin, the organic evolution is due to -
  1. A
    Reduced feeding efficiency in one species due to the presence of interfering species
  2. B
    Competition within closely related species
  3. C
    Intraspecific competition
  4. D
    Interspecific competition
View written solutionFree

Correct answer: C

Intraspecific competition leads to evolution. Variations arise naturally in a growing population due to crossing over etc. Organisms with variations better suited to their environment are favoured by natural selection, while less fitted ones are eliminated. Gradually this continued process of natural selection leads to evolution. Interspecfic struggle also plays a role in evolution but intraspecific struggle is more intense and prominent one.
