Actually there are three: Darwin, Mendel and Wallace.
The theory of evolution by natural selection.No, as however life came about the fact that it evolves is observed and observable and natural selection would still be one of the main drivers of evolution and the only driver of adaptive change.
The mechanism and main driver of adaptive change in evolution is natural selection.
All educated and not ideologically blinded scientists explain evolution by three primary mechanisms. Genetic drift, gene flow and natural selection.I have the feeling you do not know what secular means.
Darwin developed The theory of evolution by natural selection.So, to answer you question, all of it!You need to make a distinction between evolution, the change in allele frequency over time in a population of organisms, and natural selection, the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of evolution.
Evolution is a fact-based scientific theory backed up by more than a century of research and observation. It is a solid theory that fits the facts observed in biology, paleontology, and geology. Evolution adresses the origin and evolution of life, not that of the universe. ID is a religion-based concept with no substantiated evidence that science would accept as such. It is in conflict with observed facts in four main scientific disciplines: biology, geology, paleontology, and cosmology. It makes statements about everything from the origin of the universe & the earth to the origin of life and denies the evolution of species, claiming that all species were created, but offers no explanation on the mechanisms of the process other than stating they are of supernatural origin.
Jean Lamarck's theory of evolution is known as zoological philosophy or the inheritance of acquired characteristics, and stated that changes to an organisms phenotype (basically what it looks like) will cause changes to it's genotype (DNA). This has been disproved of by modern scientists, with natural selection as the main theory.
Evolution Theory, Force Theory, Divine Right Theory, Social Contract Theory
DNA molecules contain the assembly instructions for every living creature. Scientists compare DNA from ancient and present creatures to identify genetic similarities among species. The genetic similarities among species is the main evidence of evolution theory.

Mostly by explaining why these creationist criticisms are based in an incomplete understanding of the principles of knowledge and an insufficient knowledge of the relevant data. Creationists say that one of the main problems of Darwin's theory of evolution is that evolution cannot be proved. They say that the reason why it cannot be proved is because no one was there to observe the process of evolution. They call it a "theory" in the sense of an hypothesis. Scientists say that nothing is 'proved' in science, in the sense of mathematical proof. All theories are judged by the abundance and quality of the evidence in their favor. 'Being there' is not a requirement for theories of stellar fusion or of the internal workings of the atom. What matters is that the evidence can be observed in the present. And the word "theory", in science, does not carry the same meaning as used in the colloquial sense, of 'hypothesis' or 'guess'. A scientific theory is an explanation of some phenomenon or phenomena that has been extensively tested, and for which no contrary evidence exists.
His two main concepts, acquired characteristics and a innate " desire " to evolve, were both unsupported by any evidence and were not the way evolution happens. So, Lamarck's " theory " ( in the vulgar sense ) was utterly refuted by the actual evidence and process of evolution.

The three main theories of evolution are Lamarckism, Darwinism, and punctuated equilibrium. Lamarckism suggests that organisms can pass on acquired traits to their offspring, while Darwinism proposes natural selection as the main mechanism of evolution. Punctuated equilibrium suggests that evolution occurs in rapid bursts separated by long periods of stability.
There are 2 main answers:1) GOD has created us!2) Evolution!We were all created by God. Read in The Bible in Genesis, it will tell you all about the creation of the world and EVERYTHING in it. It's amazing how much God can do. He's very powerful.But if you are not religious then we came from the Sea! From Darwin's theory of evolution do we learn how we were created!
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
Many scientists dismissed the theory because it flew in the face of conventional wisdom.
