Rate of evolution
The rate of evolution is a variable of considerable interest in evolutionary biology. It concerns the limits of adaptation to natural environments as well as the limits of artificial selection.Humans ...
Quantum evolution
Quantum evolution is a component of George Gaylord Simpson's multi-tempoed theory of evolutionary change, proposed to explain the rapid emergence of higher taxonomic groups. According to Simpson, evol...
Phyletic gradualism
Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole...
Gradualism
Gradualism, from Latin gradus (“step”), is a hypothesis, a theory or a tenet assuming that change comes about gradually or that variation is gradual in nature. Similar concepts are: uniformitarianism,...

In biology, saltation (from Latin, saltus, "leap") is a sudden change from one generation to the next, that is large, or very large, in comparison with the usual variation of an organism. The term is ...

Punctuated equilibrium
Punctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological...
Rapid modes of evolution
Rapid modes of evolution have been proposed by several notable biologists ever since Charles Darwin proposed his theory of evolutionary descent by natural selection. In his classic volume On the Origi...

Punctuated gradualism
Punctuated gradualism is a microevolutionary hypothesis that refers to a species that has "relative stasis over a considerable part of its total duration [and] underwent periodic, relatively rapid, m...
Punctuated equilibrium in social theory
Punctuated equilibrium in social theory is a method of understanding change in complex social systems. The method studies the evolution of policy change, including the evolution of conflicts. The the...
