Because it is based on a massive body of evidence that provides correct predictions of what we should find.
For example, humans have 46 chromosomes and the "great" apes (chimpanzees, gorillas, and orangutans) have 48. Why is this?
It was predicted that since we were the outlier, that we had a chromosome that fused. We started searching our genome and found teleomeres in the middle of chromosome #2. What does this mean? Well, since teleomeres are only found on the ends of chromosomes, this provided the evidence that our chromosomes had a head to head fusion.
Upon more research it was found that the genes on our Chromosome #2 (the fused one) directly correlated with the genes on two of the chromosomes of the "great" apes.
It has also been used to find specific fossils by predicting where the transitional species would be AND and what depth in the geological column. This is how we found a species of animal that was an ancestor of whales which lived both on land and in the water.
It's these kinds of correct, testable predictions that make evolution scientific theory.
No, evolution is widely supported by scientific evidence and is considered a fundamental principle of biology. There is no credible scientific theory that opposes evolution.
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.
Charles Darwin in the 19th century.
Evolution itself is a fact, as it can be observered in both the environment and in the laboratory. A theory is a statement or series of statements which describes and explains a natural phenomenon based upon a solid foundation of evidence. The theory of evolution fits into the criteria of a theory.
There are no scientific theories that disprove evolution. Evolution is a well-supported scientific theory that is backed by a vast amount of evidence from various scientific fields. Any claims to the contrary are not supported by scientific consensus.
The scientific movement accepts the Theory of Evolution. The Theory is the basis for the science of biology.
No, evolution is widely supported by scientific evidence and is considered a fundamental principle of biology. There is no credible scientific theory that opposes evolution.
theory of evolution
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.
A scientific theory is a model that withstands testing, like evolution.
Yes it is
As a biological phenomenon and a scientific theory.

Darwin's Theory of Evolution is solidly based on detailed observation of many different species, and on logical analysis of those observations, hence, it is scientific.
Albert Einstein supported the theory of evolution and believed in the scientific evidence that supported it.
Because evolution is a proven, testable, scientific theory.
A theory, when proven over time, can become a law. Example: Law of Gravity and Theory of Evolution
