How life came to be is a mystery that baffled the minds of even the smartest researchers. Although the researchers found no definite answers throughout the centuries, they had created many theories that could explain the origin of modern organisms. Evolution is a prominent theory among others, as supported by ancient ancestry, fossil evidence, and genetics. Evolution is the correct theory because the evidence, which is ancestry, fossil evidence, and genetics, proves evolution to have a solid argument. First, fossils of organisms and their ancestors differ in order to fit the needs to survive, which explains evolution by showing that their skeletons change over a long or short period of time; this is similar to the definition provided by Dictionary.com.
Those animals that adapt will be more likely to survive and produce more offspring than other animals in the same environment that do not (Boyd and Silk 2000, p. 5), as maintained by Darwin’s second postulate. Phenotypes that are favored by Natural Selection include the ability to care for offspring, acquire resources, and avoid predators. The correlation between Natural Selection and Sexual Selection is the next necessary step to understanding how Sexual Selection accounts for awkward traits. The later of the two can be considered a special category of natural selection. It involves selection for traits only concerned with increasing the probability of mating (Krebs and Davies, 1993, p. 89).
Some anthropologists say the small sections of DNA found are not conclusive evidence, because modern humans show just as much variation in DNA. These people point out that individuals such as the “Portugal Kid” are hybrids of Neanderthals and modern humans, showing there was gene trading. One argument against this is that there is no skull from the ‘Portugal Kid” so it is hard to compare it to Neanderthals. Also, it is known that closely related species can breed and their offspring can be fertile, but they are still separate species (Kunzig, 161). Ot... ... middle of paper ... ...ro-Magnon.

If species are as similar as we are, genetically, physically and socially, then they should be able to share a genus. It is not degrading or upgrading to anyone, it’s just painting an accurate picture of our evolutionary past. Works Cited Carey, Benedict. Kissing Cousins.
There are several reasons why evolution is classified as a theory but the main reason is because it has never been proven. For over 200 years scientist have been trying to prove evolution and have not come close. They have tried using fossils, DNA ,every and anything to try and prove evolution. People have even tried mixing the bible with evolution, which is a very sad and pitiful thing to do http://www.talkorigins.org/faqs/faq-misconceptions.html
There were who supported it and people who didn't support the idea expressed by Darwin. But when scientists first started digging up dinosaurs bones they thought that the creatures where giant lizards or iguanas. The words deinos ‘terrible’ + sauros ‘lizard,’ “The first dinosaurs were called iguanodons. It wasn't until the fossils of two-legged dinosaurs started showing up in the 1850s that scientists had to grapple with the idea that organisms of the past were somewhat similar to ones today like, dinosaurs were reptiles, but many of them took on a diversity that's barely recognizable to us” (Crash Course). Some of these iguanodons survived today in the likes of birds such as chickens.
At first, society did not accept the evolution but that did not stop Charles Darwin from arguing that it is a fact. In conclusion, the views of society has changed since the introduction of evolution because at first society would rely upon religion to answer their questions but after the introduction of evolution they now understand that religion cannot answer every question. The past society thought that white Europeans are a divine creature which was proved to be false since we all evolved from one ancestor. There was huge amount of debate when Charles Darwin published the Origin of species and society did not accept its ideologies at first. However, as time went on it became more believable.
Evolution is the process that all living things developed from primitive organisms over billions of years ago. Up to this day know one knows exactly how evolution occurs, but there are many theories. Including, the Carolus Linnaeus theory, the Erasmus Darwin theory, the Jean-Baptiste Lamarck theory, and last but certainly not least the Charles Darwin theory. Many people are skeptic which mean they think that evolution is fake and don’t want to even hear the facts behind it, these people usually believe in creationism. In this essay I will be doing an over view of evolution.
Nuclear Power Nuclear power is known to us as a source of energy and not much more than that. We do not consider the risks of this power source in which we use. Using nuclear power plants hurts our planet by producing harmful fumes and radioactive wastes. Nuclear power plants produce radioactive waste that has to be disposed properly but even with precautions the waste stays dangerously radioactive for several years with nothing we can do about it. It is not only dangerous because of life of the radioactive waste but also the consideration that it might be spilled in an area in which can harm our planet even more and/or people and animals.
Intelligent Design is not testable and states that organisms appear abruptly however, Darwin in “An Origin of a Species” explains the commonly accepted idea of how organisms came about through the idea of evolution.

In addition, teachers may not even have the educational science knowledge to teach such highly complicated theories. According to Plutzer “Teachers in all states are expected to meet certain minimum requirements for certification. But this does not mean all science teachers are equally knowledgeable about evolutionary theory or science generally” (Plutzer, 2011, p. 620).
