Detailed explanation-1: -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 species into a new one (through a process called anagenesis).

Detailed explanation-2: -General Overviews. Gradualism in biology and geology refers most broadly to a theory that changes of organic life and of the Earth itself occur through gradual increments, and often that transitions between different states are more or less continual and slow rather than periodic and rapid.

Detailed explanation-3: -Gradualism is selection and variation that happens more gradually. Over a short period of time it is hard to notice.

Detailed explanation-4: -Darwinian gradualism suggests that differences between species are often matters of degree and not matters of kind. From: Philosophy of Biology, 2007.

Detailed explanation-5: -Individual organisms can evolve during a single lifespan. Evolution only occurs slowly and gradually. Because evolution is slow, humans cannot influence it.
