  2. Neutral theory of molecular evolution - Wikipedia

    en.wikipedia.org/wiki/Neutral_theory_of...

    The neutral theory assumes that most mutations that are not deleterious are neutral rather than beneficial. Because only a fraction of gametes are sampled in each generation of a species, the neutral theory suggests that a mutant allele can arise within a population and reach fixation by chance, rather than by selective advantage. [1]

  3. Scientific modelling - Wikipedia

    en.wikipedia.org/wiki/Scientific_modelling

    Modelling is the process of generating a model as a conceptual representation of some phenomenon. Typically a model will deal with only some aspects of the phenomenon in question, and two models of the same phenomenon may be essentially different—that is to say, that the differences between them comprise more than just a simple renaming of ...

  4. The Neutral Theory of Molecular Evolution - Wikipedia

    en.wikipedia.org/wiki/The_Neutral_Theory_of...

    The Neutral Theory of Molecular Evolution is an influential monograph written in 1983 by Japanese evolutionary biologist Motoo Kimura. While the neutral theory of molecular evolution existed since his article in 1968, [ 1 ] Kimura felt the need to write a monograph with up-to-date information and evidences showing the importance of his theory ...

  5. Unified neutral theory of biodiversity - Wikipedia

    en.wikipedia.org/wiki/Unified_neutral_theory_of...

    A neutral model that can analytically predict both the relative species abundance (RSA) at steady-state and the STD at time t has been presented in Azaele et al. (2006). [12] Within this framework the population of any species is represented by a continuous (random) variable x, whose evolution is governed by the following Langevin equation:

  6. Linear model of innovation - Wikipedia

    en.wikipedia.org/wiki/Linear_model_of_innovation

    Original model of three phases of the process of technological change: Invention is followed by Innovation, which is followed by Diffusion. The Linear Model of Innovation was an early model designed to understand the relationship of science and technology that begins with basic research that flows into applied research, development and diffusion [1]

  7. Scientific method - Wikipedia

    en.wikipedia.org/wiki/Scientific_method

    Science is the process of gathering, comparing, and evaluating proposed models against observables. A model can be a simulation, mathematical or chemical formula, or set of proposed steps. Science is like mathematics in that researchers in both disciplines try to distinguish what is known from what is unknown at each stage of

  8. Value-freedom - Wikipedia

    en.wikipedia.org/wiki/Value-freedom

    Max Weber, the creator of this concept. Value-freedom is a methodological position that the sociologist Max Weber offered that aimed for the researcher to become aware of their own values during their scientific work, to reduce as much as possible the biases that their own value-judgements could cause.

  9. Process science - Wikipedia

    en.wikipedia.org/wiki/Process_science

    Process science is the method of describing change from an inquiry-oriented process perspective. [1] [2] [3] Process science includes algorithms, heuristics, and sequences found in psychology, linguistics, anthropology, politics, and economics. [4] In sociology, processes are temporal. [5] In computer science, a process is the collective input ...
