Organisms in a population must compete for the resources as the resources are limited and the organism that compete and survives wins.
The best equipped organism survive which is known as the survival of the fittest.
Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.

The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.
