Organic evolution is the slow, generational transformation of ancestral life forms into today's diverse species.

Organic evolution refers to the gradual and continuous biological process through which the characteristics of populations of organisms change across successive generations, ultimately giving rise to new, more complex species from simpler pre-existing ancestral forms. This change occurs through the accumulation of small, heritable variations (arising from mutation and recombination), acted upon by mechanisms such as natural selection, over vast spans of geological time, leading to the tre …
