Has evolution been proved scientifically or it is a hypothesis?

Answer 1

mainly scientifically guess works if you ask me...

Answer 2

Evolution is NOT proven - you misunderstand the nature of scientific inquiry. Science never accepts anything as "proven" - it merely forms a "theory" to explain a body of observations about the world. These theories are always, of course, incomplete at describing the world and are subject to improvement. Since they are based on observation, they do not constitute a deductive "proof" like you might get in math, no matter how good they are at explaining the universe.

The canonical example is the theory of gravitation developed by Isaac Newton. For many years this was perfectly adequate in explaining gravitational phenomenon, until it was noted that certain eccentricities in the orbit of Mercury were not in agreement with Newton's gravitational theory. That is, it was a good theory, but it needed improvement. This led to the development of Einstein's general relativity theory, which better explained the workings of gravity. Newton's theory was not "wrong", per se, since it never claimed to be the truth - merely a good way of explaining the world.

Similarly, evolution is a theory with a huge amount of evidence and observation that has been used to develop it. Most laypeople do not appreciate how sophisticated our understanding of evolution really is - it is a deeply mathematical field, and we have in fact made quite a large study of the way natural selection and genetic drift affect the development of populations of all types. So, evolution is definitely not a hypothesis - a mere conjecture that has, as yet, very little or no supporting evidence.

Answer 3

Evolution, like almost all ideas in science, is a "theory." In science, you start with an idea (hypothesis), then test it out (experiment) and when you have accumulated a whole lot of really convincing evidence, then it is called a "theory."
Sometimes if you have a huge, gigantic amount of evidence, and there is absolutely not the slightest doubt about the idea, and noone objects, then you can call your idea a "Law" (like, the Law of Gravity, or the Law of Conservation of Energy and Matter)
So, why isn't Evolution a "Law"
Although scientists overwhelmingly support the idea of Evolution, there is no way to actually go back in time to watch evolution happen. We dont have time machines! So, we can look at fossils, and genetics, and physiological and anatomical relationships. But you can't absolutely, positively, unequivocally prove it. This is true of many other ideas in science, so it's nothing to get excited about. Evolution is the way it happened, unless someone comes up with a MOUNTAIN of evidence in favor of some other theory, that is larger than the MOUNTAIN of evidence that exists for Evolution.

Answer 4

There is an overwhelming amount of evidence that proves evolution is a valid theory on the small scale. We have seen organisms changing within our own lifetime - including insects becoming resistant to pesticides, strains of bacteria developing resistance to cleaners in hospitals, and many diseases becoming immune to drugs once effective in treatment. The basic principle behind evolution - that populations of organisms may change genetically / phenotypically through time in responce to external pressures - is indeed valid.

However the idea that all organims came from an earlier form (I.E. fish to amphibians to reptiles to mammals, etc) has little valid proof. Evidence theoretically may be in the fossile record but if not destroyed by geologic processes can be very easily mis-interpreted (remember the ceolocanth - thought to be an extinct shallow water transitional fish - turns out it very much alive and a deep water marine fish). There are many living organisms that could be considered transitional stages however - walking catfish, mudskipper fish, etc.

So yes, scientifically Evolution has been Proven and Disproven many times over. Because of this, it will always be considered a valid theory as to how life has changed over time.

Answer 5

Well, it's still a theory. It does have some scientific evidence to support it, though a few major gaps still exist that have yet to be explained. I'm pretty sure it's a widely accepted theory in the scientific community, and seems to make some sense.

Answer 6

A hypothesis is a guess, a theory is a guess with evidence supporting it to be true.

There is evidence supporting the theory of evolution, but it has not been proven beyond a shadow of a doubt. However, the theory of relativity has not been totally proven, either, but we trust it enough to build rockets to Mars...

Answer 7

It's pretty darn close to proven. We've already observed bacteria evolving to become more resistant to antibiotics. The real debate isn't whether evolution works, but whether it is responsible for all life on Earth.

Answer 8

evolution of life has ben divded in two parts 1. biological evolution 2. chemical evolution
CHEMICAL evolution: it is scientifically proved by MILLER&C.H.UREY

Answer 9

its a theory which is heavily supported by much scientific evidence. I dont think its something that can ever be proven.

Answer 10

Proven. Go and search the web on evolution.
