its been accumulated by like how plants like go through a faze you know like what it needs water sun. In nature useful traits have been accumulated in plants and animals by selection. Most of the time it is natural and among cultivated plants and domesticated animals, it is man made.
its all based on ressesive vs. dominate traitts and backround and luck.
They evolve and adapt so they have traits hat are useful to them, by Natural selection. This means that members of a species that are isolated, well, natural selection makes those with the best chances for survival mate with each other and produce offspring with that trait.
Natural selection is when biological organisms with favorable traits survive and reproduce more successfully than organisms that do not possess such traits. Organisms with negative or less useful traits survive and reproduce less successfully than organisms lacking such harmful traits. Natural selection played a huge part in the evolution of the great barracuda. The barracuda had to adapt their distinctive shape, design, and skills over the years and did so through many generations.
Humans are the only cause of artificial selection. Humans take organisms that they think are useful, or may become useful and they breed them true for traits they want in the organism and they cull the organisms that do not possess traits that humans find useful. not all animals can be artificially selected though.

Natural selection doesn't directly occur in the genes or alleles. Natural selection occurs in the "real world", in which the organisms with the desirable traits are living, while the organisms with undesireable traits are dying or otherwise failing to reproduce. Nature is "selecting" these animals with useful traits, which survive to reproduce and pass on these genes. The genes are what give animals the certain traits they need in order to survive. The individual alleles give the variation within a certain trait. For example, within the gene for fur color, there can be an allele for white, and an an allele for brown. The bunny that gets the brown allele will probably suvive in the wild. (Unless the environment is snow!)
