Charles Darwin developed the Theory of Evolution by Natural Selection before most of the fossil evidence for the theory existed. He looked at the micro-evolution practised by pigeon breeders, the evidence on the Galapagos Islands and elsewhere, and realised that evolution was the only explanation that made sense. He saw that related species were to be found in close proximity, evidence of evolution from a single parent species, whereas a single act of Special Creation ought to have placed the species anywhere on the globe where the environment was suitable.

The fossil record shows clear evidence of evolution over a period of more than a billion years. Certainly, at first, there were no transitional species among the many species that had been found, although scientists saw much that did confirm the Theory of Evolution. That has changed, because many transitional species have been found. A recently discovered 220-million year old fossil, Odontochelys semitestacea, is a new species of turtle that had a fully formed shell on its underside, but only a small partial shell on its back, extending from its backbone. As well as a partial shell, Odontochelys semitestaceaalso had ribs that had begun to widen, thus demonstrating that the fully developed shell of later turtles evolved from the ribs of earlier species. Tiktaalik roseae is the name of a newly discovered lobe-finned fossil fish from the late Devonian period, that is a transitional form to amphibians, with basic wrist bones and simple fingers, as well as the robust ribcage necessitated by existence out of water. Odontochelys semitestacea and Tiktaalik roseae are two more pieces in the jigsaw that shows conclusively how life on Earth evolved from earlier species.

Scientists can now use DNA evidence from modern species to support the fossil record, as further evidence of evolution.

Scientists believe in evolution because there is overwhelming evidence from multiple scientific fields such as Paleontology, genetics, and comparative anatomy that support the theory. Fossil records show a progression of organisms over time, genetic similarities between different species provide evidence of common ancestry, and observations of natural selection and adaptation in action further support the theory of evolution.

When did scientists believe that chemical evolution occurred?

Scientists have believed that chemical evolution occurred about 4 billion years ago, shortly after the formation of the Earth. This process is thought to have led to the development of the first life forms on our planet.


When did scientist believe chemical evolution occur?

Scientists believe that chemical evolution occurred around 3.5 billion years ago.


When do scientists believe the chemical evolution occurred?

Scientists believe that chemical evolution occurred around 3.8 to 3.5 billion years ago on Earth, leading to the development of life from simple organic molecules. It marked the emergence of the first self-replicating molecules, laying the foundation for the evolution of diverse life forms over time.

Where do scientists believe the chemical evolution occurred?

Scientists believe that chemical evolution occurred in the early Earth's oceans, where simple molecules combined and formed more complex ones through processes like lightning, UV radiation, and undersea vents. These conditions allowed for the formation of organic compounds, leading to the development of life over time.


When do scientists think chemical evolution occurred?

Scientists believe that chemical evolution occurred around 4 billion years ago, shortly after Earth was formed. This process involved the formation of complex organic molecules from simpler compounds through reactions such as polymerization and the assembly of molecules on mineral surfaces.


Where do scientists believe chemical evolution occcured?

Scientists believe that chemical evolution, or the formation of complex organic molecules from simpler compounds, occurred in the early Earth's oceans, hydrothermal vents, or deep-sea environments. These environments provided the necessary conditions, such as energy sources and a variety of chemical compounds, for the spontaneous formation of complex molecules that eventually led to the origin of life.


Where do scientists believe evolution occurred?

Probably in tidal pools.


At the beginning of the universe scientists believe that stellar evolution contained only what two elements?

Scientist believe that stellar evolution contained only hydrogen and then helium.


Do scientists believe man was created by God or that they just evolved?

Different scientists hold different beliefs. Many scientists accept the theory of evolution as a scientific explanation for the diversity of life on Earth. However, there are also scientists who believe in theistic evolution, which posits that evolution is a process guided by a higher power, such as God. Ultimately, beliefs about the origins of humans vary among scientists.


Where do scientists believe chmical evolution occurred?

The higher elements are forged in the center of stars. Most stars can create up to about element 6-8 on the periodic table, but any elements higher than that require a super nova.


Is it true that only atheists accept the theory of evolution?

No. Many theists, including Christians, believe that evolution occurred. Belief in some sort of god and belief in evolution are not mutually exclusive. Some even believe evolution was guided by some divine entity such as God.
