A . Evolution because it is just a theory

The argument that evolution is just a theory ‘ usually stems from a misunderstanding of the scientific concept of the word theory ‘ The argument is commonly used by laypersons who only have a casual knowledge the theory of evolution . These persons use the argument because they incorrectly believe that theory ‘ means that there is no real proof

However , the theory of evolution has a very large body of evidence that supports it . Although evolution is generally accepted by the scientific world , it is still [banner_entry_middle]

labeled a theory ‘ because a scientist must keep an objective and open mind . As it stands now , many scientists who have devoted their professional lives to the study of the biology and its history accept the theory of evolution

Persons who use the just a theory ‘ argument may think that the theory of evolution was invented ‘ by armchair scientists ‘ but this is not so . While the theory of evolution may not have had the backing of a large amount of evidence in its early years , the evidence that supports evolution has steadily grown . The overwhelming amount of evidence (such as the fossil record , genetic similarities between species , etc ) that we now have for evolution naturally leads to the conclusion that evolution actually happened

A person who denies the theory of evolution because it is just a theory ‘ needs to do some research and to back up his claims . There is enough evidence for the theory of evolution for scientists to deem it acceptable , and all this evidence must be refuted if evolution is to be denied

B . We should not worry about air pollution because through natural selection , the human species will develop lungs that can detoxify pollutants

Aside from the moral wrongness of the implications behind the above argument (that the weak should be allowed to die , the argument is weak Natural selection is the survival of the fittest . What this means is that the weak will die while the strong will survive , allowing them to produce similarly strong offspring . Although there may still be some natural selection to a limited extent (such as people with very weak lungs dying too young before they are able to reproduce , natural selection is no longer a significant factor in the death or survival of specific humans . Natural selection no longer applies to a great extent to modern humans (or at least those who live in developed and developing countries . This is because through modern medicine and technology , even weak humans will be able to survive and reproduce

Additionally , natural selection is also a very slow process , but air pollution , in contrast , continuously and rapidly increases , especially if we do not worry about air pollution ‘ as the argument above states In this case , natural selection may mean the death of everyone , because even if natural selection were allowed to play its part , air pollution will go out of hand and possibly kill all humans before they can catch up through natural… [banner_entry_footer]
