Why is evolution considered s theory?
The generally accepted theory of evolution by natural selection was proposed by Charles Darwin
Basically, it is "survival of the fittest." As certain traits of species become in-adaptable to certain environmental changes, the organism with those traits will die out. The… organism of that species with the stronger genes will live and reproduce, thus creating more of the strong trait and less of the other.
The word 'theory' means it is an explanatory framework for some set of observational data. As to your question: while there is an overwhelming amount of observational data sup…porting the general tenets of evolutionary theory, and it is now impossible to rationally reject these tenets, it will technically always remain an explanatory model - a theory.
It is considered a theory because it is substantiated by evidence. In the scientific sense, a theory is a proposition that is supported by evidence, either direct or indirect.… With out some of observable evidence, it is only a hypothesis. Theories CAN be changed or proven false as new information is learned or as the INTERPRETATION of information is changed. Evolutionary theory can be said to be true, as the theory itself has evolved over time! :)
Evolution is a process, theories of evolution are theories which explain that process
they look the same when you take x-rays so it most mean the we came from the same organism improved ans: by monitoring how and what an embryo grows as it matures, you can see… a lot of things that you cannot see in a fully grown animal, for instance, human embryos have a tail at certain stages in developement, they also surprisingly have gills at one stage, two of these pairs of gill slits disapear as the embryo grows, and the final pair move upwards to become your eustacian canals and ears. this shows us that humans once had tails and that hundreds of millions of years ago we also had gills which means that at some point in our past we were once sea dwelling.
It is the foundation of all modern biology.
It flies in the face of Established Religion and every thing it stands for. Although evolution makes no claim about religion or even how life sprang from un-life, religious a…dherents see it as undermining the belief that God created everything and as science trying to replace God or someother supernatural diety. All evolution seeks to explain is the changing of living organisms from one form to another according to the dictates of the environment and natural selection, all of which could be ascribed to divine design or scientic explanation.
Basically, theory of evolution is the theory that explains the diversity of life. Many believe the father of evolution was Comte de Buffon, a French naturalist. However, h…e was unable to come up with a reasonable mechanism that drives evolution. Charles Darwin later came up with natural selection as the mechanism that drives evolution and wrote about it in his book On the Origin of Species.
Yes, by definition evolution is a theory (hence it is called the 'theory of evolution'). Despite what some would try to argue, this is not a statement against evolution's cr…edibility and the concepts involved. Rather, it is a statement of complete and unanimous support by the scientific community, which finds evolution to be the simplest and most logical explanation for the phenomena involved, as well as fitting the evidence, providing predictions which can be tested and passing all tests that ever attempted to break it. Another answer It is also a hypothesis, a fact and a process, and none of these are a problem either. However, as much as some would like to see this as a problem, we must first note what a theory is. In scientific terms, a theory is a hypothesis which has been experimentally confirmed, has made accurate predictions about phenomena, accommodates all known facts about the subject, and is widely accepted as correct. We must contrast this definition with that often used by those who don't understand it; in that case, a theory would be more correctly referred to by the term hypothesis, which is an explanation of something but which has yet to be experimentally confirmed. So in basic terms, a theory is an idea which - after a lot of testing and experimentation and criticism and debate - has been determined to fit all the facts, explain those facts consistently, and make reliable predictions. In short, it's about as close as you can get to certainty. The vast majority of the scientific community - about 99.9% of all qualified scientists - accept it as such. There is no better explanation of how life on earth came to be the way it is now.
it is backed up by scientific evidence.
Modern evolutionary theories are still based off of Charles Darwin's theories of evolution published in 1859. They have yet been proven as scientifically inadequate or incorre…ct, nor have new, more plausible theories been created so Darwin's theories are still the basis for modern evolutionary science.
Because it is an internally consistent explanation of a mechanism of evolution that is supported by many lines of converging evidence, that has been repeatedly tested and is c…apable of making testable predictions. Pretty much the scientific definition of theory.
The theory of evolution is relevant to every aspect of the science of biology. It shows relationships between different aspects of biology which otherwise would not seem to b…e related. Thus, it unifies the science of biology.
Evolution is the change in allele frequency (genotype) over time in a population of organisms resulting in alterations of the phenotype. Change over time gives rise to the div…ersity of species. The theory of evolution by natural selection is the nonrandom survival and reproductive success of randomly varying organisms. This is the main adaptive driver of evolution and can lead to speciation. All organisms are variations and the environment, the natural selector, preferentially chooses those with beneficial traits to be reproductively successful in the immediate environment at a greater rate than their fellow population members. As their descendents possess these traits, the alleles shift in the population gene pool and evolution occurs. Gene flow and genetic drift also cause evolution, especially in small populations, but they are not adaptive drivers.
evolution is considered a theory and not a hypothesis or law because there is no real proof or evidence to prove evolution.
There are five major points to Darwin's theory of evolution. These are: 1)members have heritable variations; 2)in a population, more individuals are produced than can surv…ive; 3)some individuals will adapt to better survive; 4)an increasing number of individuals will have adaptations due to genetic inheritance; and 5)natural selection results in a population that is adapted to the environment.
