Darwin's theory of evolution is probably one of the most popular theories every conceived. This theory includes how life on earth started and how it evolves from specie to specie.

There are many documents and historical information to prove that this theory is true including numerous books and historical documents written by Darwin himself.

The first portion of Darwin's theory of evolution pertains to the beginning of life on earth. Scientists believed that in order for life to exist four basic elements had to be present. These elements were carbon, hydrogen, oxygen, and nitrogen (CHON). Darwin thought that life could have came about from a mixture of these very materials on Earth's surface. As it is written in The Cradle of Life The Discovery of Earth's Earliest Fossils "Indeed, the notion that CHON-containing monomers might be easy to make on the primordial Earth dates from Darwin and a famous passage in a letter he wrote in 1871 to his botanist friend, Joseph Hooker: "It is often said that all of the conditions for the first production of a living organism are now present, which could ever have been present.

But if (and oh! What a big if!) we could conceive in some warm pond, with all sorts of ammonia and phosphoric salts, lights, heat, electricity etc. present, that a protein compound was chemically formed ready to undergo still more complex changes, at the present day such matter would be instantly devoured or absorbed, which would not have been the case before living creatures were formed." The life-starting scenario dreamed by Darwin is astonishingly close to what we think today. But only the rudiments of biochemistry were known in Darwin's time, and he was a...
