  2. r/K selection theory - Wikipedia

    en.wikipedia.org/wiki/R/K_selection_theory

    The terminology of r/K-selection was coined by the ecologists Robert MacArthur and E. O. Wilson in 1967 [2] based on their work on island biogeography; [3] although the concept of the evolution of life history strategies has a longer history [4] (see e.g. plant strategies).

  3. Biological value - Wikipedia

    en.wikipedia.org/wiki/Biological_value

    Common foodstuffs and their values: [18] (Note: These values use "whole egg" as a value of 100, so foodstuffs that provide even more nitrogen than whole eggs, can have a value of more than 100. 100, does not mean that 100% of the nitrogen in the food is incorporated into the body, and not excreted, as in other charts.) Whey protein concentrate: 104

  4. Selection coefficient - Wikipedia

    en.wikipedia.org/wiki/Selection_coefficient

    Selection coefficient, usually denoted by the letter s, is a measure used in population genetics to quantify the relative fitness of a genotype compared to other genotypes. . Selection coefficients are central to the quantitative description of evolution, since fitness differences determine the change in genotype frequencies attributable to selecti

  5. R* rule (ecology) - Wikipedia

    en.wikipedia.org/wiki/R*_rule_(ecology)

    Understanding the differences between the R* theory and its major alternative the CSR triangle theory is a major goal in community ecology for many years. [6] [7] Unlike the R* theory, the CSR theory predicts that competitive ability is determined by relative growth rate and other size related traits.

  6. Evolutionary biology - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_biology

    Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth.

  7. Lawrence Kohlberg's stages of moral development - Wikipedia

    [1] [29] Most cultures do place some value of life, truth, and law, but to assert that these values are virtually universal requires more research. [27] While there had been some research done to support Kohlberg's assumption of universality for his stages of moral development, there are still plenty of caveats and variations yet to be ...

    Kohl's announced Tuesday that Amazon customers will be able to return items at all of its stores beginning in July. The news cements a two-year collaboration between a department store retail ...

  9. Stabilizing selection - Wikipedia

    en.wikipedia.org/wiki/Stabilizing_selection

    Stabilizing selection (not to be confused with negative or purifying selection [1] [2]) is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. This is thought to be the most common mechanism of action for natural selection because most traits do not appear to change drastically over time. [3]
