Explanation:

Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a species due to evolution by natural selection,

In evolution by natural selection, the following must occur

reproduction
the inheritance of specific traits from parent to offspring- heredity
variations in the number of offspring each individual produces
variations in physical characteristics

Further Explanation:

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.

During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

This is called natural selection- an evolutionary mechanism which changes the inheritance frequencies of these beneficial alleles over several generations of offspring. These offspring are said to develop adaptations which ensure their survival, the alleles for which become more stable within a population over time.
