The theory of evolution by natural selection, first formulated in Darwin’s book “On the Origin of Species” in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring. 


Theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations. The theory of evolution is one of the fundamental keystones of modern biological theory.

Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.

The theory is sometimes described as “survival of the fittest,” but that can be misleading, Pobiner said. Here, “fitness” refers not to an organism’s strength or athletic ability, but rather the ability to survive and reproduce.

The first person who explained how evolution happens was Charles Darwin with his scientific theory of natural selection

Charles Darwin observed that although individuals in a species shared similarities, they were not exact copies of each other; there were small differences or variations between them. He also noticed that everything in the natural world was in competition.

The winners were those that had characteristics which made them better adapted for survival. For example, they were stronger, faster, cleverer or more attractive than others in their species. These living things were more likely to reproduce and pass on their useful characteristics to their offspring.

Individuals that were poorly adapted were less likely to survive and their characteristics were not as likely to be inherited.

Over time, the characteristics that help survival become more common and a species gradually changes. Given enough time, these small changes can add up to the extent that a new species altogether can evolve.


Creationism, the belief that the universe and the various forms of life were created by God out of nothing (ex nihilo). It is a response to modern evolutionary theory, which explains the emergence and diversity of life without recourse to the doctrine of God or any other divine power. Mainstream scientists generally reject creationism.


Biblical creationists believe that the story told in Genesis of God’s six-day creation of all things is literally correct. Others, such as old-Earth creationists, believe that a creator made all that exists, but they may not hold that the Genesis story is a literal history of that creation. Both types of creationists, however, believe that changes in organisms may involve changes within a species (often understood as the “kind” mentioned in Genesis 1:24) or downward changes such as negative mutations, but they do not believe that any of these changes can lead to the evolution of a lower or simpler species into a higher or more-complex species. Thus, the theory of biological evolution is disputed by all creationists.

Creationism became the object of interest among conservative religious groups following the publication in 1859 of On the Origin of Species by Charles Darwin (1809–82), the first systematic statement of evolutionary theory. Within two decades most of the scientific community had accepted some form of evolution, and most churches eventually followed suit. In the early 20th century, some state legislatures in the United States banned the teaching of evolution on the ground that it contradicted the biblical creation story, which they considered a revealed truth. The result was the famous Scopes Trial (the so-called “Monkey Trial”) of 1925, in which a high-school teacher, John T. Scopes, was convicted of unlawfully teaching the theory of evolution (he was later acquitted on a technicality). Creationism has largely been promulgated by conservative Protestant Christians

We must distinguish clearly between research which investigates the creation around us, and contemplation of the beginnings of creation.

Should Christians Push for legislation to have creationism taught at their public schools?

We understand the difference between historical and observational science and between fallible man and infallible God. The observable principles and facts of science do not contradict biblical Christianity. We maintain that Genesis 1–11 is history, not fictitious “storytelling” by ignorant, primitive people. We choose to trust the Word of the God who knows.
