Evolution Theory

Evolution theory, also known as evolutionary theory, or the theory of evolution, is based on the idea that all life on earth is related and gradually changes over time. The theory primarily explains the ongoing speciation of life since its emergence on Earth.

Scientific Theory

The word theory entered the English language in the late sixteenth century meaning conception, mental scheme, speculation. Arts and sciences began using the word in the seventeenth century but in a different meaning.

Contrary to popular belief, in science, a theory is not the best-educated guess scientists have about a certain natural phenomenon. On the contrary, a scientific theory is a well-confirmed type of explanation of nature, made in a way consistent with modern scientific methods.

A scientific theory is a framework for observations and facts in the natural world, and it does not only address existing scientific data but also makes predictions. Scientific theories are repeatedly tested confirmed through experiments or observation.

Following are some examples for scientific theories:

Cell theory

The Theory of Gravity

General relativity

Evolution

Evolution

Evolution is change in the heritable characteristics of biological populations over successive generations.

We know that evolution is a fact thanks to massive evidence from other branches of science such as paleontology, genetics, zoology, and molecular biology.
