Punctuated Equilibrium: theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis; when significant evolutionary change occurs, it is generally restricted to rare and rapid events of branching speciation called cladogenesis (process by which a species splits into 2 distinct species, rather than 1 species gradually transforming into another)
