Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	Gradualism
B	Punctuated Equilibrium

Explanation:

Detailed explanation-1: -Evolution is a gradual process in which something changes into a different and usually more complex or better form. The mechanisms of evolution include natural selection acting on the genetic variation among individuals, mutation, migration and genetic drift.

Detailed explanation-2: -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-3: -Individual organisms can evolve during a single lifespan. Evolution only occurs slowly and gradually. Because evolution is slow, humans cannot influence it.
