9 mar 2020 · The Price equation, therefore, measures the effect of natural selection on every gene frequency, and on the breeding value of any trait, while the fundamental theorem measures natural selection in its totality as the additive genetic variance in relative fitness.
In the theory of evolution and natural selection, the Price equation (also known as Price's equation or Price's theorem) describes how a trait or allele changes in frequency over time. The equation uses a covariance between a trait and fitness, to give a mathematical description of evolution and natural selection.
9 mar 2020 · The Price equation has found widespread use in many different areas of evolutionary biology. Here, we have illustrated how it can also provide useful insight into the evolutionary biology of infectious diseases.
11 mar 2008 · The Price equation is a simple mathematical statement about change. In its usual formulation, it describes how the average value of any character — body weight, antler size, proclivity to altruism — changes in a biological population from one generation to the next.
9 mar 2020 · The Price equation is a statistical summary of evolutionary change, and it is widely acknowledged that statistical relations do not necessarily imply or directly map onto causal relations. So, caution is required when making claims about causality based solely on the Price equation.
16 wrz 2016 · In evolutionary biology, the Price equation, also labelled as Price’s theorem, plays this role (Rice 2004; Frank 2012a). Developed originally by George Price (1970, 1972), the Price equation describes the evolution of a population from one generation to another in a simple algebraic language.
Price equation is, how we should think about it, and its value and limitations in reasoning about evolution. Subsequent articles will show the Price equation in action, applied to kin selection, causal analysis in evolu-tionary models and an information perspective of natural selection and Fisher’s fundamental theorem.
