As for natural selection:
Nature selects animals whose phenotype allows it to survive, thus pass on its favourable qualities to next generations.
Animals whose phenotype disallows it to compete to gain food or survive will perish. (Survival of the fittest)

Phenotype is caused by genotype.

As the favourable qualities cumulate in the organism generation after generation, after a long period of time the organism will be different from the original --> new species.
This is evolution.
