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.
Edwin Darwin did not propose a separate theory on evolution. The theory of evolution is commonly attributed to Charles Darwin, who put forth the concept of natural selection as the mechanism driving evolution. Edwin Darwin does not have a notable theory associated with evolution.
Rather both. Evolution, the change in allele frequency over time in a population of organisms, is an observed and observable fact. The theory of evolution by natural selection explains this fact with overwhelming evidences from many different disciplines.
Yes, evolution is a theory. But it is not "just a theory" in the sense that you probably mean. In layman's terms, we might speak of a theory as simply an idea or an opinion, such as "Well, that's YOUR theory..." In science, it is something else entirely, and when something becomes scientific theory, it has been very well substantiated. It is more synonymous with the word "fact" in this usage, unlike the previous usage I used as an example. in fact, all scientific discoveries are considered theories. hell, the fact that our bodies are made up of cells that reproduce is still just a theory.
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.
Evolution is a scientific theory that is supported by overwhelming evidence from various fields such as paleontology, genetics, and microbiology. The term "theory" in science does not mean a guess, but rather a well-substantiated explanation based on evidence. While evolution is widely accepted among scientists, it is not considered a fact in the same way as established scientific laws because theories are subject to modification based on new evidence.
You mean the evolution theory? Darwin
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.
Edwin Darwin did not propose a separate theory on evolution. The theory of evolution is commonly attributed to Charles Darwin, who put forth the concept of natural selection as the mechanism driving evolution. Edwin Darwin does not have a notable theory associated with evolution.
If you mean the theory of evolution and the survival of the fittest: That would be Charles Darwin.
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
Rather both. Evolution, the change in allele frequency over time in a population of organisms, is an observed and observable fact. The theory of evolution by natural selection explains this fact with overwhelming evidences from many different disciplines.
If you mean, "are they ignorant for being in evolution," then no. The theory of evolution is a well-founded, heavily detailed theory with an enormous amount of evidence behind it. The theory of evolution is used to study disease. It's used to study agriculture. It's used to bring together all of the sciences pertaining to life.
When you say evolution theory implies to accept the idea you just inserted, do you require us to buy it ad nominee or are you going to explain what is evolution theory and what do you mean while using it?I had to write ad nominee, because it didn't accept the original word as correct.
It does not. Cell theory is fully compatible with evolutionary theory. Does this mean we know everything about the evolution of cells? No. We say we do not know, not that cell theory shows that evolutionary theory is incorrect. ( except, of course, if you are referring to heritability. This Darwin got wrong, but this is not directly related to cell theory )
Who do you mean? Wallace or Darwin? Either way they both wrote a book about it.

"Theory" in the "Theory of Evolution" phrase (and in any other similar phrase, like "theory of relativity") means that evolution is just something we suppose explains how world works, until we find a better way to explain things..."Theory" actually refers to the inherent inability of human to know the 'real' reality - or even if such 'real' reality exists (as the world of ideas of Plato).
