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. Gradualism states that evolution occurred slowly, while punctuated equilibrium posits that it occurred rapidly followed by long periods of no change.

Examining the fossil record gradualism and punctuated phyletic speciation suggests that abrupt mutations in a few regulatory genes occur after a species has. Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur a species can evolve by only one of these, or by both scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly.

Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual [1] when evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).
