Better evidence, especially from genetics. When Charles Darwin first proposed the theory of evolution by natural selection his mechanism of heredity was dead wrong. He posited a blending type of heredity. When Gregor Mendel's work was rediscovered in about 1900 particulate inheritance was brought to the forefront of evolutionary thinking and the synthesis of the 1930's and '40's cooperated this thinking with Darwinian though to give us modern evolutionary theory.
There is no " theory of evolution " as evolution is a fact. The theory is; the theory of evolution by natural selection and explains much about the fact of evolution. Charles Robert Darwin and Alfred Russel Wallace come up with the theory of evolution by natural selection, though natural selection is a phrase coined by Darwin.
Charles Darwin
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
Charles Darwin is the scientist who is most widely recognized for his contribution to evolutionary theory through the study of natural selection. Darwin's work provided the foundation for our understanding of how species evolve over time.
The modern theory of evolution may be referred to as natural selection, Darwinism, the Modern Evolutionary Synthesis, or sometimes simply evolution.
How it can change in response to its enviroment
the theory about how organisms change over time.
Short and memorably answer. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of adaptive change leading to evolution.
Natural selection explains adaptive change in the immediate environment.
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.
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
which is not part of darwins theory of natural selction
Darwin's theory of evolution by natural selection does not incorporate theories about geological change. Those are the domain of geology, not biology.
Natural selection
Evolution by natural selection.
