Shifting balance theory Shifting balance theory The shifting balance theory is a theory of evolution proposed in 1932 by Sewall Wright, suggesting that adaptive evolution may proceed most quickly when a population divides into subpopulations with restricted gene flow. The name of the theory is borrowed from Wright's metaphor of fitness landscapes (evolutionary landscapes), attempting to explain how a population may move across an adaptive valley to a higher adaptive peak. According to the theory, this movement occurs in three steps: Although shifting balance theory has been influential in evolutionary biology, inspiring the theories of quantum evolution and punctuated equilibrium, little empirical evidence
Evolutionary theory of the self is by studying brains with deficits in activation of the anterior cingulate that bring problems when identifying self from non-self. This problem is prevalent in mental disorders such as schizophrenia, autism, and late-stage Alzheimer’s, where the ability to differentiate self vs other is compromised. Further research should use the results of Munevar's study and continue on to dissect the paradoxes and problems of traditional conceptions, while focusing on the evolutionary biology of the brain. Overall, the research done on the Evolutionary Theory of Self is promising and provides fruitful insight to the possibility of discovering new conclusions on what we
