Sexual production is a means of recreating more of a species. Once there is a gene change whether for the good or bad, and solely if the organism survives to reproduce its gene, then it will be passed on to its children and going further on until there is a large amount of a species with that specific gene. This species evolved. Evolution occurs because of gene changes.
No species exists in a vacuum; every form of life on Earth interacts over time with other organisms, as well as with its physical environment. For that reason, the evolution of one species influences the evolution of species with which it coexists by changing the natural selection pressures those species face.
