It sought explanations of natural phenomena in terms of physical laws that were the same for all visible things and that did not require the existence of any fixed natural categories or divine cosmic order. Variations of this idea became the standard understanding of the Middle Ages and were integrated into Christian learning, but Aristotle did not demand that real types of organisms always correspond one- for- one with exact metaphysical forms and specifically gave examples of how new types of living things could come to be. Lucretius followed Empedocles in his masterwork De rerum natura (On the Nature of Things). Moreover, previously held notions about evolution, such as orthogenesis, evolutionism, and other beliefs about innate. The importance of natural selection as a cause of evolution was accepted into other branches of biology.

Evolution by natural selection is a process demonstrated by the observation that more offspring are produced than can possibly survive, along with three facts about populations: 1) traits vary among individuals with respect to morphology, physiology, and behaviour (phenotypic variation), 2) different traits confer different rates of survival and reproduction (differential fitness), and 3) traits can be passed from generation to generation (heritability of fitness). Existing patterns of biodiversity have been shaped both by speciation and by extinction. The fossil record includes a progression from early biogenicgraphite. Evolution is change in the heritable characteristics of biologicalpopulations over successive generations.
