In science, a theory is a well-substantiated explanation based on evidence and testing. The ideas about evolution are called theories because they have been extensively researched, tested, and supported by a wide range of scientific evidence from various fields such as genetics, paleontology, and comparative anatomy. Evolutionary theory is considered one of the most robust and well-supported theories in biology.
Although natural selection is affected by geology, and some knowledge of geology is certainly necessary to be able to interpret the evidence for the various phylogenies of evolution, these theories themselves do not affect geology. Evolution therefore remains a matter of biology, not geology.
Current theories that conflict with Darwin's theory of evolution include Lamarckism, which suggests acquired traits can be passed down through generations, and Saltationism, which proposes that large evolutionary changes can happen suddenly. Supporters of Lamarckism cite cases of epigenetics as evidence, while proponents of Saltationism point to instances of punctuated equilibrium in the fossil record to support their claims.
I believe you are referring to microevolution and macroevolution. These theories both support evolution, but each in their own way. Microevolution is the most common belief today. This states that evolution is happening so rapidly that we don't even notice it. The mutations needed for evolution happen so quickly and on such a small scale that we never realize it's happening until afterwards. Macroevolution is exactly the opposite. This states that the mutations take so long that we never notice it. Both theories, in fact, were proposed because people were asking why, if evolution actually did take place, we could never see it happening.
One unintended consequence of the theory of evolution is the misconception that it promotes the notion of "survival of the fittest" as a justification for social inequality or unethical behavior. This misinterpretation can lead to misunderstandings about the complexities of evolution and human behavior. Additionally, some may use evolution to support eugenic ideologies, which can have harmful implications for society.
The vast majority of scientists support evolution. There is no longer any debate in the scientific community about whether evolution occurs, only the mechanisms in which evolution acts upon is debated.
Experiments.
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
The theories are evolution deal with the fact that every being on the planet today came from a now-extinct species. This goes for humans as well. Scientists believe that humans evolved from now-extinct mammals during the Late Cretaceous period. Evidence proves people came from a member of the gibbon family.
There is not enough evidence to support these new theories. More tests and research needs to be carried out before these theories can be proved.
Theories don't support theories.Only evidence that comes from observation or experiment supports or demolishes theories.
It is generally thought to support the Theory of Evolution.
