The different theories of evolution basically states that all the plants and animals have their origin in their earlier existing types. It further states that there are few discernible differences and modification in the succeeding generations.
The five theories of the state are the Pluralist theory, the Elite theory, the Marxist theory, the Functionalist theory, and the Systems theory. Each of these theories offers a different perspective on how power is distributed and how the state functions within a society.
Some theories of human evolution include the Out of Africa theory, which suggests that modern humans evolved in Africa and migrated to other parts of the world. The Multiregional theory suggests that modern humans evolved simultaneously in different regions of the world. The Recent African Origin theory posits that modern humans originated in Africa and replaced other hominid populations.
Some of the main evolutionary theories include Darwin's theory of natural selection, which proposes that species evolve over time through the process of adapting to their environment; the theory of genetic drift, which suggests that random changes in gene frequencies can lead to evolution; and the theory of punctuated equilibrium, which posits that evolution occurs in short bursts of rapid change followed by long periods of stasis.
Gradualism proposes that evolution occurs through a slow and continuous process, with small changes accumulating over time. Punctuated equilibrium, on the other hand, suggests that evolution happens in rapid bursts of change separated by long periods of little to no change. Both theories address the concept of how species evolve over time, but they differ in the pace and patterns of these changes.
In the scientific sense of the word 'theory' (ie. testable explanatory model), there is just the one theory of evolution: evolutionary theory, which incorporates the central theses of common descent and natural selection.
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.
The evolution of public administration in Kenya can be traced through different theories such as the traditional model, the colonial model, the post-colonial model, and the current New Public Management model. These theories reflect the changing political, economic, and social contexts within which public administration has developed in Kenya over time.
Do you mean the formation of the Earth? If so, the two competing theories are creation and evolution, as in the formation of the observable universe by the Big Bang.

No, there are no other theories but the theory of evolution by natural selection that explain so much about evolution.
There is only one central "theory of evolution", which is the theory of evolution by natural selection that Charles Darwin pioneered. There have been different theories in the past - such as Jean-baptise Lamarck's theory of acquired traits - but these lost their status of scientific theory when they were shown to be wrong.

Natural selection, I'm not sure, and Consumer-based evolution, respectively.
by making theories
Darwin's theories were revolutionary because they proposed a mechanism, natural selection, by which evolution could occur through the adaptation of populations to their environment. This was different from the prevailing idea of fixed species created by a divine force. Darwin's focus on variation within a population and the importance of competition and survival for shaping evolution set his theories apart from his predecessors.
