Evolutionary Worldview Has developed over the last two hundred years It is a worldview that is made up of change, order, direction progress and perfectibility

Change All evolutionary theories whether physical, biological, or social phenomena are theories of change The are based on the idea that past, present, and future differ from eachother In general, all theories by the occasional intervention of a higher power or extraordinary force in a otherwise static universe stand in direct opposition to the evolutionary worldview which sees change as the regular and characteristic feature of natural and social systems Uniformitism Catasphorism

Change and Order Evolution only works in a society that is also changing Bergson and white noted that “evo;lution is a materialistic theory, is reduced to the role of being another word for description of changes to external reaction between portions of matter. There is nothing to evolve because one set of external relations is as good as any other set of external relationships. There can merely be change,purposeless and unprogressive

Order Because many theories were not satisfied with evolution merely being change with no description The came up ordering evolutionary change with complexity, homeostasis, and environmental buffering Theory of successsion= ecological theory that attempt to restore ordering with the following schema 1. the total number of species 2. species diversity taking both account both of number of species and of their relative abundance 3. biomass diversity including both the physical size each species and if their relative abundance 4. the ration of total rte of production of living material of total standing of crop material

Order continued The development of law of evolutionary transformation of a system and of the appropriate dimensions of description is a dialectical process that cannot be carried by a priori assumptions about or description Evolutionary or population genetics has been able to come with kinematic theory which look at the motion of evolutionary, but has had to give up the idea of the attempt to introduce an ordered description. Evolutionary or population genetics= elaborate theory of change in the frequecy of genes to populations as a consquence of mutations, migrations,breeding structure of poluation and natural selection Theory framed entirley in term of an extensive list changes in time

Direction Ordered description of the states in an evolutionary proecess…. Includes temporal direction to evolution. Either unilineal or cyclical Evolutionary ecology = idea thtat complexity, stability or the ratio of biomass to productivity increases over time and species diversity decreases or increases toward and intermediate value It is suggested that organisms are becoming more complex, and more physiologically homeostatic.
