Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species. Evolutionary processes depend on both changes in genetic variability and changes in allele frequencies over time. The study of evolution can be performed on different scales.
The organisms exhibit different characteristics due to different genotypes (variation). If these characteristics are favoured by the natural environment, the organisms with these variations survive and propagate, and may form different species. Thus, evolution is the outcome of natural selection.
