Name one scientific theory that was proved to be true?
Well, that's not possible. It is called a theory because it can't be definitively proved. For instance, we know gravity exists, so it is a scientific law, but there is no definite proof for evolution, so it is just a theory.
How did humans evolve through natural selection?
Modern homo sapiens developed from a species known as homo erectus; erectus was the first hominid to walk upright hence the Latin name. The first appearance of sapiens is around 200 thousand years ago.Homo erectus developed from a species named homo habilis, the first hominid to be using tools. The first appearance of erectus was around 1.8 million years ago (or 1.25 mya if you follow the idea that erectus developed from the very similar ergaster, with ergaster being the step between habilis and erectus).Homo habilis is believed to have developed from Kenyanthropus platyops. Habilis first appeared between 2.5 and 2 million years ago.Platyops is believed by some to be either a member-species of the genus Australopithecus, or to be a misidentification of another extant species afarensis within that genus. Both of these would explain the heritage it has; the specimens found were given their own genus and species in the interim. Kenyanthropus platyops first appeared around 3.5 million years ago.At this point, the exactness of the human evolutionary tree is disputed; several specimens have been found, the characteristics and times of which complicate the tree somewhat. However, there are at most two or three further ancestors before we reach the most recent common ancestor of chimpanzees and humans 5 to 7 million years ago - it is some interesting research to go back further, and shall be left to the reader if they are interested.
Is there a difference in evolution theory between neo Darwinism and Darwinism theory?
Well a simplified definition of evolution is a process of something changing over time. Darwinian evolution (or biological evolution) pertains to the changing of species over time through the genes, its a chemical and physical process that has to do mainly with the fields of biology, chemistry, and for a smaller extent (though my field) psychology and the social sciences. It's refered to as "darwinian" evolution because Charles Darwin first proposed the idea of evolution by natural selection as a way of explaining the varieties of the species. Cultural evolution refers to the changing of cultures over time. A big proponent of this field is Daniel Dennett who refers to "memes" (originally coined by Richard Dawkins) as the cultural counterpart to genes. Cultural evolutionists argue that cultural phenomon such as fads, sayings, language, or beliefs also undergo a "natural selection" of a sort by having to be continually reproduced or else they are forgotten (the meme equivalent to a species going extinct).
Can a reaction mechanism be determined without an experiment?
While theoretical approaches like computational chemistry can provide insights into reaction mechanisms, experimental validation is necessary to confirm the proposed mechanism. Experimentation allows for the observation of intermediates, rate laws, and other key details that are crucial for elucidating the complete reaction pathway. Theory and experiment are often combined to develop a comprehensive understanding of reaction mechanisms.
Because ideas about evolution by natural selection have never been false what term can be used to describe evolution by natural selection?
We often say the theory of evolution when we refer to the idea that life evolved through natural selection.Note that the theory of evolution, at least as it is expressed in modern evolutionary synthesis, is far and away the bestexplanation for the countless facts we've discovered about life on earth and its long history here. In that light, modern evolutionary synthesis (MES) is considered fact by almost all of the scientific community.The fact that the ideas expressed have not been proved false does not keep some from trying. And though the questions raised and the contrary opinions expressed are, in general, healthy for science on the whole, there is an undercurrent of desperate intent on the part of some investigators who attack the theory. These exchanges are spoken to in other posts here on WikiAnswers. Links can be found below.
Is the mechanism which proved species change over time?
The mechanism that has been proven to show species change over time is natural selection, as proposed by Charles Darwin. This process involves the differential survival and reproduction of individuals with advantageous traits leading to changes in populations over generations.
Do giraffes smile because they don't know what's going on?
Yes. I proved this in my book, Natural Selection.

How mutation can lead to change in population over time?
with the theory of natural selection, darwin proved that it is all down to "the survival of the fittest" meaning, that the strongest of a species will always be the last to die off, therefore it has more chance of reproducing and handing its genes down.
Who was the first scientist to propose a theory about how life evolves?
Charles Darwin. His theory is The Theory of Natarual Seletion. A theory that has been proved even today
What is the name of the famous book of evolution?
Though I'm not sure it was his first book, most are referring to the following:The full, original title of Darwin's most famous book published in 1859 was:On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for LifeLater, in 1872,the title of his book is shortened to The Origin Of Species
How did Charles Darwin contribution impact science?
Charles Darwin's contribution to science, particularly his theory of evolution through natural selection, revolutionized our understanding of how species evolve over time. His work laid the foundation for the field of evolutionary biology and has had a profound impact on numerous scientific disciplines, from biology to anthropology. Darwin's observations and ideas continue to influence scientific research and shape our understanding of the natural world.
How did Benjamin Franlin contribute to our knowledge of energy?
He proved that electricity was natural to nature.
Why was Darwin's theory of evolution controversal?
Darwin's theory of evolution was controversial because it challenged existing religious beliefs about the creation of life, suggesting instead that species evolved over time through natural selection. This clashed with the prevalent idea of divine creation as outlined in religious texts. Additionally, some people were uncomfortable with the implications of humans evolving from earlier species.
Who signed declaration of independence and discovered electricity?
Ben Franklin, but he didn't "discover electricity". He proved that electricity was in the natural world.
The league of nations proved to be an ineffective mechanism for solving global conflicts is the united nations similar should the us drop out of the un for that reason why?
no. because it only makes sense to try again.
Why was Benjamin Franklin a scientist?
Yes and an inventor. He proved that electricity was natural in the environment. Invented the lighting rod, Franklin stove, and bifocals.
