Can a reaction mechanism be determined without an experiment?
A reaction mechanism can be proposed using computational studies. But needs to be experimentally proved.
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.
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.
Who proved continental drift?
Alfred Wegener Proved The theory of Continental Drift.
How was the cosmoligical constant proved wrong by Hubble?
Albert Einstein's cosmological constant was proved wrong by Hubble as he proved the universe is expanding so it doesn't need a constant to stop it imploding.
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.

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 Benjamin Franlin contribute to our knowledge of energy?
He proved that electricity was natural to nature.
Why is therE a big difference in aging of creation and evolution?
The main difference is intimated by the methods used to work out the age differences. Creation is part of a story written by people in the Bronze Age in the Middle East which was borrowed from earlier stories which probably originated in, what is now, Iraq, for which there is no scientific evidence. Evolution is a term normally associated with "On The Origin of Species, by Means of Natural Selection" by Charles Darwin, which has been proved by evidence from many sources in many disciplines.
Theory on the evolution of the state?
Evolution - a unifying principle of biologyThe theory of evolution states that modern organisms are descendants of ancient organisms and that modifications accumulated over time explain the apparent changes and differences among modern forms of life. This 'descent with modification' theory was central to Charles Darwin's argument of biological evolution, an idea spearheaded by Jean-Baptiste Lamarck (1744-1829). The idea of evolution proposes that animals and plants can change over time, and are not static forms created at once and independent of each other. Lamarck and Darwin proposed different explanation of how these changes may occur. Darwin's proposal of natural selection has proved correct and evidence from biology, earth science, and cosmology all corroborate the basic mechanism of natural selection.

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.
What connection does Denis Diderot see between natural world and religion?
Because he traveled the sea and ate tacos. He proved that tacos were yummy!
