Evolution Is It Really A Theory?

One way to test the evolution theory is to look at what is “Written In The Rocks”. Fossils have been known since ancient times hence the myth of the griffin coming from the beaked dinosaur Protoceratops. The formation of fossils requires a certain amount of

There have been many theories of evolution and how it is brought about and what it is exactly. Charles Darwin a scientist who came up with his theory of evolution and how it works. Darwin felt as though evolution to him was that it occurred through natural selection. Natural selection is the process of only traits that will survive are passed to the next generation. Species selection operates on variation provided by the largely random process of speciation and favors species that speciate at high rates or survive for long periods and therefore tend to leave many daughter species (Stanley, 1975 ). So Darwin believed that the next generations of animals or different species were created by taking only the traits of species

The first and quite possibly the best evidence for evolution is Homology. Homology is when species share similarities that are signs of common ancestry such as homologous structures. Homologous structures are ones that derive from a common ancestral structure (“Evidence of Evolution…”). These can prove to be very solid reasoning when arguing

The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a "warm warm little pond" and that it took billions of years for the present diversity of living things to evolve. At the time, it was thought that the few "missing links" in the fossil record would be soon filled.(Darwin, 1927 ). Today, however, there is today a considerable body of scientific evidence that refutes this entire theory.

According to Ms. Witsaman, evolution is not the theory of how life began, which is a common misconception nowadays, but the theory of how life has changed over time. Theories are predictions which are backed up by several evidences and supported by scientists. The evidences that scientists use now to prove include fossils, homologous structures, analogous structures, vestigial structures, embryology, biogeography, and biochemicals. Fossils are the remains of living things that once roamed the Earth. Homologous structure are structures shared by different organisms that have similar structure but different functions. Analogous structures are the opposite, they have similar functions but completely different structure.Vestigial structures are

All primates have a common ancestor, from millions of years ago. Go further back, and you will find a common ancestor for all mammals. Then a common ancestor for all vertebrates, then animals, then all life on earth. How closely two organisms are related can be deduced by looking for homologous structures, structures that look similar and have a similar function. This proves that the organisms descended from a common ancestor. Station 1 contained multiple vertebrate skeletons. They all had homologous structures, including a vertebral column and a rib cage. This shows that all vertebrates are related and come from a common ancestor with a

Homologous Structures – structures that have different functions but have a common ancestry. (ex. – arm of a human, flipper of a whale, and the wing of a bat)

Evolution theory is not true because it gives a vague explanation of how the world developed to be what it is today and it also fails to explain why it is no longer going on today. As absurd as it is there are people in the world today who believe it majority of them being atheist.

When scientists compare embryo similarities we discovered that humans embryos and animal embryos are almost exactly alike. We go through the first two stages as the same embryos as the animals but when go to the third stage we start to differentiate and grown into the animal or human. Scientists also look at similar DNA structure that gives us evidence that evolution occurred and shows us what similar ancestors we have. When we look at analogous structures we see that the structure is not common and is not evidence of evolution but when we look at homologous structures we see that there is evidence that evolution occurred. For example cats and humans have the same arm bone structure. When scientists looked at homologous molecules they see the alike DNA

The fossil record is evidence of evolution. Fossils are often fingerprints of evolution. They help scientists track how species evolved

The theory of evolution is a species will adapt to the environment it is in over generations to ensure they have the desired traits to survive and reproduce. An exceptional example of evolution is the saltwater crocodile, who has gone through up to 200 million years of evolution since the cretaceous period. Adding on to evolution the proof that supports it is the DNA found that links current species with ancient ancestors, geology how species have certain traits that make them perfectly suited to an environment, and direct observations on how a current species si alike to a past species. The theory of evolution is supported by current species for example the saltwater crocodile and many other physical observations. The individual who created

For example, A fish fossil called Rhipidistian was found. Because the bones from it are similar to amphibian. People thought that it is the transitional form between fish and amphibian. But when the living fossil called Coelacanth was found. The hypothesis was overthrew. Because the phylogeny of these two amphibians is very close. Research shows

Common Ancestry, also known a common descent, is the idea that everything evolved from one single ancestor (Levine and Miller pg#). This theory relies on the fossil record being in a certain order, evolution occurring today, and having genetic similarities to animals. Fossils do not lie, which is why many scientists search nature’s records for the answers to questions about our ancestry including finding a link between humans and apes along with searching for evidence to support the evolutionary timescale.

The theory of a common ancestor has plenty of fossil evidence to back it up. Throughout the years fossils from different human ancestors from different ages have been found. In 1856, the fossils of neanderthals were found. Neanderthals lived from 200,000 to 300,000 years ago, they had a big brain made of 1400 cc’s, they were social, big creatures that learned to use and make tools and made cave art. Neanderthals also buried their dead, like modern day humans. In 1892, the fossils of homo erectus were found. Homo erectus lived about 1.8 million years ago. They had a brain of 600 to

Examples are A dolphin’s flipper, a human arm and the leg of a cat are examples of homologous structures.”(n.d.). Retrieved June 21, 2017
