That each living thing on this earth derives from a single less complex ancestor common to all species
This theory is known as the theory of evolution, which states that living organisms have descended and diversified over time from common ancestors through the process of natural selection and genetic mutation.
Darwin's Theory of Evolution states that individuals within a species that inherit traits that give them a better chance of surviving and reproducing in their environment are more likely to pass on their genes to the next generation. Over time, this process leads to changes in the characteristics of a population, resulting in evolution.
The modern theory of evolution states that all living organisms have descended from a common ancestor through the process of natural selection acting on genetic variations.
population
Evolution is a fact. The theory of evolution by natural selection is what you are trying to talk about. When someone says " evolution is just a theory " they are using the vulgar, common sense of the word theory. They mean guess, hunch and the like. The theory of evolution by natural selection is in the scientific sense of the word theory, which means a body of explanatory work supported by myriad lines of converging evidence that has been tested rigouusly and replicated often. Any good dictionary uses this scientific meaning of theory as the primary meaning of the word.
Evolution Theory
The theory that states governments developed from family ties is called the "patrimonial theory." This theory suggests that early rulers maintained power through family lineage, passing down leadership roles and maintaining control within a particular family group.
Cell theory does not contradict evolution. Cell theory states that all living organisms are composed of cells, while evolution explains how these cells and organisms change over time through the process of natural selection. Both concepts are supported by scientific evidence and are compatible with each other.
This question has been debated for many years. There are two theories, a religious theory and an evolution theory. The religious theory states that man kind was created by god. The other theory is that man kind came about through evolution.
Theory of evolution refers to animals and plants evolution along the time. Language evolution is another issue, not entirely related to the theory of evolution. It follows the theory of evolution on some way but it is related to culture evolution, not to the physical attributes evolution.

it is evolution
Evolution is an observed and observable fact. The theory of evolution by natural selection explains many things about evolution. The theory generates testable hypothesis, as any good theory does. Remember, theory is the highest concept in science.
The modern theory of evolution states that all living organisms have descended from a common ancestor through the process of natural selection acting on genetic variations.
There are many books that describe the theory of evolution. For example, there is a book called Evolution: The Remarkable History of a Scientific Theory.
The best way to respond to this is to explain that there is the fact of evolution and the theory of evolution. Evolution is defined as genetic change within a population. This is an easily observable fact both in nature and the laboratory. The theory of evolution is an explanation for the diversity of life on earth based on the observable facts that evolution does indeed occur. It is exactly the same situation with gravity. Gravity is a fact, an easily observed physical phenomenon. But there is also a Theory of Gravitation, an explanation for the phenomenon itself and how it works. That there is a theory for both evolution and gravity does not mean the facts of evolution and gravity are any less true.
