Why do people believe in the theory of evolution?

Answer 1Because they accept the myriad of evidence that underlines the Theory of Evolution by Natural Selection.Answer 2Because they relied on evidences, observations, experiments. These are the basic premises of sciences. For an idea to be called a 'theory' in science required more evidences and tests, etc. A theory in science means more than what most lay people realize. A hypothesis in science is closer to what lay people think of as a 'theory' in daily usage. So when you hear the Theory of Evolution, there is substantial evidence behind it, just like there is for the Theory of Relativity or Theory of Gravitation.On the other hand, just because something has lots of evidence behind it does not mean it's correct. However, it takes a lot of counter-evidence to overturn a theory. Remember, it took a long time and substantial evidence to change the theory that the earth was not the center of the universe.


Theory on the evolution of the state?

Evolution - a unifying principle of biologyThe theory of evolution states that modern organisms are descendants of ancient organisms and that modifications accumulated over time explain the apparent changes and differences among modern forms of life. This 'descent with modification' theory was central to Charles Darwin's argument of biological evolution, an idea spearheaded by Jean-Baptiste Lamarck (1744-1829). The idea of evolution proposes that animals and plants can change over time, and are not static forms created at once and independent of each other. Lamarck and Darwin proposed different explanation of how these changes may occur. Darwin's proposal of natural selection has proved correct and evidence from biology, earth science, and cosmology all corroborate the basic mechanism of natural selection.

What are the basic priciples behind the theory of evolution?

The theory of evolution is quite simple. The principle behind it states that every living being on Earth today came from a species that is now extinct. Over millions of years, each species has undergone evolution and has changed them to make them able to live in today's world. For example, humans evolved from a gibbon species and birds evolved from dinosaurs.
