  8. Evolution(noun)

    that series of changes under natural law which involves continuous progress from the homogeneous to the heterogeneous in structure, and from the single and simple to the diverse and manifold in quality or function.

It is also applied to explain the existence and growth of institutions, manners, language, civilization, and every product of human activity. The agencies and laws of the process are variously explained by different philosophrs

  1. Evolution

    Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins. All life on earth is descended from a last universal ancestor that lived approximately 3.8 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological traits, or by shared DNA sequences. These homologous traits and sequences are more similar among species that share a more recent common ancestor, and can be used to reconstruct evolutionary histories, using both existing species and the fossil record. Existing patterns of biodiversity have been shaped both by speciation and by extinction. Charles Darwin was the first to formulate a scientific argument for the theory of evolution by means of natural selection. Evolution by natural selection is a process that is inferred from three facts about populations: 1) more offspring are produced than can possibly survive, 2) traits vary among individuals, leading to different rates of survival and reproduction, and 3) trait differences are heritable. Thus, when members of a population die they are replaced by the progeny of parents that were better adapted to survive and reproduce in the environment in which natural selection took place. This process creates and preserves traits that are seemingly fitted for the functional roles they perform. Natural selection is the only known cause of adaptation, but not the only known cause of evolution. Other, nonadaptive causes of evolution include mutation and genetic drift.

The Nuttall Encyclopedia

  1. Evolution

    the theory that the several species of plants and animals on the globe were not created in their present form, but have all been evolved by modifications of structure from cruder forms under or coincident with change of environment, an idea which is being applied to everything organic in the spiritual as well as the natural world. See Darwinian Theory.

The Roycroft Dictionary

  1. evolution

    1. A word that has reclassified in an entertaining manner our impermeable and eternal ignorance. 2. The growth of a thing from the simple to the complex, and the wasting away of the complex until it is simpler than ever. 3. The one superstition that is cordially hated by theologues.

U.S. National Library of Medicine

  1. Evolution

    The process of cumulative change over successive generations through which organisms acquire their distinguishing morphological and physiological characteristics.

The Foolish Dictionary, by Gideon Wurdz

  1. EVOLUTION

    A clever trick performed by one Darwin, who made a monkey of Adam.
