Evolutionary Dynamics of Collective Behavior Selection and Drift: Flocking, Collapse, and Oscillation
IEEE Transactions on Cybernetics
|June 21, 2016
Summary
This study introduces a selection-drift dynamic model to understand social behavior evolution. The model reproduces flocking, collapse, and oscillation patterns, offering insights into social norms and cultural trends.
Area of Science:
- Social dynamics
- Evolutionary game theory
- Computational social science
Background:
- Collective social behavior formation is a complex phenomenon.
- Understanding how populations evolve behaviors amidst conflicting alternatives is crucial.
Purpose of the Study:
- To formulate a selection-drift dynamic model for behavior imitation and exploration.
- To analyze behavior evolution patterns on various network structures.
Main Methods:
- Developed a selection-drift dynamic model.
- Simulated behavior evolution on homogeneous, heterogeneous, and asymmetric behavior networks.
- Analyzed phase transitions and survival conditions for optimal behavior.
Main Results:
- Reproduced flocking, collapse, and oscillation patterns.
- Unveiled a phase transition from flocking to collapse on homogeneous networks.
- Proposed a mechanism for optimal behavior consensus on heterogeneous networks.
- Demonstrated that asymmetry induces behavioral oscillations.
Conclusions:
- The selection-drift model effectively characterizes social behavior evolution.
- Network structure significantly influences behavioral outcomes.
- Results provide insights for understanding and controlling social norms and cultural trends.

Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.

01:09Mutation, Gene Flow, and Genetic Drift
65.6K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

01:46Types of Selection
46.1K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

01:21Frequency-dependent Selection
24.4K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

01:20Evolutionary Psychology
1.2K
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.
