Punctuated equilibrium in social theory is a conceptual framework for understanding the process of change in complex social systems. The approach studies the evolution of policy change, [1] including the evolution of conflicts. [2] The theory posits that most social systems exist in an extended period of stasis, which may be punctuated by ...
Gersick's study of naturally occurring groups departs from the traditionally linear models of group development. Her punctuated equilibrium model (Gersick, 1988, 1989, 1991) suggests that groups develop through the sudden formation, maintenance, and sudden revision of a "framework for performance".
v. t. e. In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolutionary change for most of its geological history. [1] This state of little or no morphological change is called stasis.
Gould's initial work on punctuated equilibrium was coauthored with Niles Eldredge. [20] Gould's model of punctuated equilibrium drew attention to episodic bursts of evolutionary change followed by periods of morphological stability. He challenged the conventional model of gradual, continuous change - called phyletic gradualism. [21]
The equilibrium model of group development (equilibrium model) is a sociological theory on how people behave in groups. The model theorizes that group members will work to maintain a balance, or equilibrium, between task-oriented (instrumental) and socio-emotional (expressive) needs. [1][2] A group can be successful if it maintains this ...

The word phyletic derives from the Greek φυλετικός phūletikos, which conveys the meaning of a line of descent. [2] Phyletic gradualism contrasts with the theory of punctuated equilibrium, which proposes that most evolution occurs isolated in rare episodes of rapid evolution, when a single species splits into two distinct species, followed by a long period of stasis or non-change.
A group of people collaborating. Teamwork is the collaborative effort of a group to achieve a common goal or to complete a task in an effective and efficient way. [1][2] Teamwork is seen within the framework of a team, which is a group of interdependent individuals who work together towards a common goal. [3][1] The four [clarification needed ...
