Who proposed natural selection as a mechanism of evolution?
At the Linnaen Society meeting sometime in 1858 Charles Robert Darwin and Alfred Russel Wallace had both their papers presented before the Society on which they proposed the idea of natural selection as a mechanism of evolution.
What is the name for the process that causes a species to evolve?
Evolution is enabled by natural selection: the ability of a species through its individuals to make long-term improved changes in its response to its environment through beneficial mutations, resulting in the species being able to reproduce itself more successfully than before.
What scientist suggested that organisms slowly acquired physical characteristics?
Charles Darwin and his theory of evolution. Strictly speaking, Charles Darwin did not put forward the "theory of evolution". He publish a book called "On the Origin of Species by Means of Natural Selection OR The Preservation of Favoured Races in the Struggle for Life". The theory of evolution had been around for a long time, in fact, his grandfather, Erasmus Darwin, had proposed evolution 75 years before Charles published his book. Charles Darwin gave us the driving force for evolution - Natural Selection. There had been suggestions for evolution and evidence in fossils well before Charles Darwin. It is just that nobody could work out why until Charles.
Can evolution occur without natural selection?
Natural selection is the differential fitness of diverse phenotypes, causing some individuals to reproduce more than others according to their own relative fitness. Evolution is the change in gene frequencies of a population between generations. Therefore, natural selection can indeed occur without resulting in evolution, as changes in mean fitness do not necessarily lead to changes in gene frequencies. For example, a deleterious allele may affect only homozygotes in a population. Thus, homozygotes may be selected against in equal proportions, causing them both to decrease in frequency at the same rate. While heterozygotes would have higher fitness, the mean change in frequencies would still equal zero. Both the dominant and recessive alleles are still present at the same frequency as before they were acted on by selection, due to the relative increase in heterozygotes.
What does the modern synthesis of evolutionary theory mean?
It means a synthesis was created between systematic biology, population biology, genetics, paleontology and botany to form the modern theory of evolution by natural selection. Before 1930 all biologists, and other disciplines, were confirmed in evolution but not all were sold on natural selection as the main driver of adaptive change, especially geneticists. By mathematical paraphernalia showing that gradual genetic change over time could drive evolution and a broad agreement among the other branches of biology and earth science we have the modern synthesis, some times called the Neo-Darwinian synthesis.

Scientific theories about evolution before the Darwin's discovery of natural selection?
Thomas Malthus' essay on the tragedy of the commons is thought to be a significant precursor to Darwin's Theory of Evolution.
Who proposed the idea of the theory of evolution?
The idea of evolution was thought of long before Darwin, by a man named Count Buffon. What Charles Darwin did was to successfully come up with the mechanism of evolution, known as natural selection.
Did Charles Darwin coin the concept of evolution?
Charles Darwin did not coin the concept of evolution, but he is famously known for developing the theory of evolution by natural selection. Evolution as a concept had been discussed by earlier scientists and philosophers before Darwin. Darwin's contribution was to provide a comprehensive explanation for how evolution occurs through the mechanism of natural selection.
How does the theory of evolution disprove the belief that natural selection prepares an organism to adapt to its environment Natural selection occurs before changes in the environment. A population ch?
To begin with, a theory can not prove or disprove anything until it is proven itself.
Who Came up with the idea of natural selection independent of Darwin?
The scientist Alfred Russel Wallace actually studied the idea of natural selection before Charles Darwin. Wallace and Darwin later became research colleagues, but Darwin became more well known after publishing "The Origin of Species".
Did the Theory of Natural Selection come before the Theory of Relativity?
Yes, by around 50 years. Natural selection was developed in the 1850s-60s. Relativity was developed in 1905.

How and when did the argument between creation and evolution begin?
Just after the beginning of the 20th century a religious revival called fundamentalism gained traction in America and the battle commenced. Of course there was opposition before then, but now the opponents of evolutionary science were literalists in their biblical interpretations and well organized in their opposition to the theory of evolution by natural selection. There is no real argument, Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much of the fact of evolution. Creationism is pure nonsense.
How did Darwin use scientific methods before presenting his ideas on the Theory of evolution by natural selection to?
Darwin collected extensive data from nature, including observations from his voyage on the HMS Beagle and research on various species. He also conducted experiments and analyzed patterns in nature to develop his theory of evolution by natural selection. Overall, Darwin employed scientific methods such as observation, experimentation, and analysis to support his ideas.
Did Huxley writes that the theory of evolution was by no means the sole product of Darwin?
Possible so, as the theory of evolution by natural selection, though his greatest product, was by no means Darwin's only production. Just before he died he produced a treatise on earthworms that is still relevant today.
