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 know about the self. Evolutionary theory of the self When trying to understand the self in terms of the brain, neuroscientists have found contradictory results and paradoxes. Nevertheless, Gonzalo Munevar has argued that neuroscience in an evolutionary context can give a proper explanation of the self. His Evolutionary Theory of the Self depends on, “the ability by the brain to coordinate new sensory information in light of the organism’s internal states and in the context of its personal history and genetic inheritance." His theory is an alternative conception for the explanation of the self, which takes into account the evolutionary
