The Great Chinese New Year 2023 The scientific theory of evolution by natural selection was conceived independently by two british naturalists, charles darwin and alfred russel wallace, in the mid 19th century as an explanation for why organisms are adapted to their physical and biological environments. Evolution, theory in biology postulating that the various types of plants, animals, and other living things on earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.

Darwin and a scientific contemporary of his, alfred russel wallace, proposed that evolution occurs because of a phenomenon called natural selection. in the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Evolution is a process of continuous branching and diversification from common trunks. this pattern of irreversible separation gives life's history its basic directionality. Evolution is the process by which species change over time through the gradual accumulation of genetic variations, driven by mechanisms like natural selection, genetic drift, and mutation, leading to the development of new traits or species.

Evolution is the process by which species change over time through the gradual accumulation of genetic variations, driven by mechanisms like natural selection, genetic drift, and mutation, leading to the development of new traits or species. Evolution is a process that results in changes in the genetic material of a population over time. evolution reflects the adaptations of organisms to their changing environments and can result in. Darwin published his theory of evolution in on the origin of species (1859), with carefully reasoned evidence to support this theory that all life on earth evolved from a common ancestor. Evolution explains how microscopic single celled organisms eventually gave rise to the vibrant explosion of life we see today. it tells us how species adapt, survive, diverge, and sometimes disappear. In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. the theory of evolution is based on the idea that all species are related and gradually change over time.
