The nonrandom survival and reproductive success of randomly varying organisms.
All organisms are variations. More organisms are born than can possible survive on the resources available. Those organisms that vary in ways that aid their survival and reproduction, over other organisms whose variations do not aid them to do these things, are selected and their genes become well represented in the population while the disadvantageous genes become less well represented. Also the characteristics must be heritable
A pseudoscientific theory
The theory of rapid evolution rather than over a very long time.
He proposed a theory that attempts to explain why and the fact of evolution works.It is, so far, the best and most accurate theory that adequately explains why evolution happens.
The theory of evolution by natural selection explains how adaptive change may lead to speciation,\. As any good scientific theory it explains much but not everything. I seriously doubt, except in an ultimate sense, that you can explain why Gothic literature is now popular with evolutionary theory.
In science, a hypothesis and a theory differs in that a hypothesis is a conjecture based on empirical observation or theoretical derivation yet unproven or by any experimental work, and that a theory is a hypothesis that has been rigorously tested by many researchers and supported by strong evidence. Evolution is a theory that has been repeatedly tested, supported by overwhelming evidence, and can be used to explain natural phenomenon very well.
No, there are no other theories but the theory of evolution by natural selection that explain so much about evolution.
It doesn't. Evolution is explained by population genetics, evolutionary theory.
the theory of evolution

William Gilbert used a terella in an attempt to explain his theory that the Earth is a giant magnet.
How it can change in response to its enviroment
The Ladder Theory attempts to explain the frustrating mystery of why women sleep with certain men. The theory is a type of sexual evaluation for both sexes.
Albert Einstein did not propose a theory of evolution. His primary contributions were in the fields of physics, particularly in the theory of relativity and the equation E=mc^2. Evolution is a biological theory developed by Charles Darwin to explain the diversity of life on Earth through the process of natural selection.
A pseudoscientific theory
The modern theory of evolution is also known as the synthetic theory of evolution or the modern synthesis. It combines Darwin's theory of natural selection with genetics and other fields of biology to explain how organisms evolve over time.
The theory of evolution by natural selection. It explains evolution; the change in allele frequency over time in a population of organisms. Why organisms change over time in differing environments.
Two major theories that attempt to explain hearing are the place theory and the frequency theory. The place theory suggests that different sound frequencies activate different areas on the basilar membrane in the cochlea, while the frequency theory proposes that the rate at which nerve impulses are generated in response to sound waves determines pitch perception.
