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.
• Evolution relies on there being genetic variation? in a population which affects the physical characteristics (phenotype) of an organism.
• Some of these characteristics may give the individual an advantage over other individuals which they can then pass on to their offspring. In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.

mass noun

• 1The process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.

  The idea of organic evolution was proposed by some ancient Greek thinkers but was long rejected in Europe as contrary to the literal interpretation of the Bible. Lamarck proposed a theory that organisms became transformed by their efforts to respond to the demands of their environment. Lyell demonstrated that geological deposits were the cumulative product of slow processes over vast ages. This helped Darwin towards a theory of gradual evolution over a long period by the natural selection of those varieties of an organism slightly better adapted to the environment and hence more likely to produce descendants. Combined with the later discoveries of the cellular and molecular basis of genetics, Darwin's theory of evolution has, with some modification, become the dominant unifying concept of modern biology

  ‘Most do believe that evolution works by natural selection on changes in organisms due to random changes in their DNA, and the evidence for this is overwhelming.’

The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.

Sumber: Cambridge Dictionary

=======================================================================

Evolution is change in the heritable characteristics of biological populations over successive generations.^[1][2] These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.^[3] Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population.^[4] It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.^[5][6]

Evolution

First published Fri Aug 25, 2017

Evolution in its contemporary meaning in biology typically refers to the changes in the proportions of biological types in a population over time (see the entries on evolutionary thought before Darwin and Darwin: from Origin of Species to Descent of Man for earlier meanings).

Definition of evolution

1a: descent with modification from preexisting species : cumulative inherited change in a population of organisms through time leading to the appearance of new forms : the process by which new species or populations of living things develop from preexisting forms through successive generationsEvolution is a process of continuous branching and diversification from common trunks. This pattern of irreversible separation gives life's history its basic directionality.— Stephen Jay Gouldalso : the scientific theory explaining the appearance of new species and varieties through the action of various biological mechanisms (such as natural selection, genetic mutation or drift, and hybridization)Since 1950, developments in molecular biology have had a growing influence on the theory of evolution.— NatureIn Darwinian evolution, the basic mechanism is genetic mutation, followed by selection of the organisms most likely to survive.— Pamela Weintraub
