Evolution
How does new species derive? Evolution, is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. Speciation by natural selection has been a topic of much debate for many years and the foundation of the evolution theory. The role of natural selection in speciation first described by Darwin has been widely accepted. Speciation remains to be up for debate. There are many evidences that both support and refute the idea of speciation by natural selection. Theorist Charles Darwin, the father of the “Evolution Theory”, purported that natural selection is about how organisms that are better adapters to their environment survive and …show more content…

Long neck giraffes were the result of a mutation. Since their necks were long they found food. They survived and multiplied and short neck giraffes didn’t. Speciation is how a new kind of plant or animal species is created. This happens when a group within a species develops its own unique characteristics. Darwin used fossils and similarities between related living organisms. (Evidence for Evolution). Darwin also emphasized the role of natural selection and competition in shaping species and keeping them in separate ecological niches. (CITE) There is scientific evidence in favor of speciation by natural selection. Research states, “Along path leads from the origins of primitive "life," which existed at least 3.5 billion years ago, to the profusion and diversity of life that exists today. This path is best understood as a product of evolution. (Evidence Supporting Biological Evolution)” It is set to believe that the idea of evolution is understood as life that has existed more than 3.5 billion years ago. By means of natural selection, in 1859, Charles Darwin published a book by the name of “On the Origin of Species” that provided …show more content…

(WIKI CITE)” There are five types of evidences that support evolution, they are ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA and similarities of embryos (Evidence for Evolution). Research states, “But the processes by which planets, stars, galaxies, and the universe form and change over time are also types of evolution. (The Origin of the Universe, Earth, and Life)”
Although there is scientific evidence in favor of speciation by natural selection, there are also scientific evidence opposing speciation by natural selection. Research states, “Belief in evolution is a remarkable phenomenon” (The Scientific Case against Evolution). The author, Henry M. Morris, Ph.D., provides evidence that proves that evolution is not happening now and has not happened in the past. It is clear that individuals have never seen it happen, so some may conclude that there isn’t

The concept of evolution has been a back and forth conversation and will probably be for as long as we know it. I personally support the concept of evolution. I believe that it is what has made everything to be the way that it is now. One example that is often used to show evolution are the finches in the Galapagos. This is a biogeographical example because the finches are different depending on which island or location they were on.

In this summary of "Was Darwin Wrong?" by Quammen I will explain the evidence behind the theory of evolution and evaluate each of the five categories of evidence of evolution. Darwin proved evolution in multiple ways each of which Quammen discusses. First, to prove his position, Quammen expressed the scientific evidence behind theories their strong standing in the scientific community. Quammen does this by using examples such as the atomic theory and the theory of continental drift both of which are strong beliefs in the science community. Therefore, he expressed the strength of the theory of evolution and explained how it is more than just an idea.

In addition, scientists use the homologous structure as evidence for evolution by using structures with different appearances and functions that derived from the same body parts in a common ancestor. Furthermore, natural selection is evidence for evolution because for example, when Darwin collected birds they were a closely related group of distinct species, but the different beak shapes were related to food gathering. Artificial selection is another piece of evidence for evolution in which operates by favoring individuals with certain phenotypic traits allowing them to reproduce and pass their genes to the next generation. Overall many biologists accepted Darwin’s theories but there are some objections such as how evolution is not demonstrated, no fossil intermediates, the intelligent design argument, evolution violating the second law of thermodynamics, proteins are too improbable, the irreducible complexity argument, and how natural selection does not imply

Evolution is supported by the fossil record, and how scientists can see similarities in DNA. To see how organisms are related,scientists can see that they have homologous structures and scientists can look in the fossil record and see common ancestors. When scientists look into the fossil record, they can see how organisms may have evolved. They look further back and see common ancestors. scientists can look at DNA and see how things are similar in other organisms, they can see that things may have had common ancestors and evolved from the same thing.

Evolution Evolution, the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth all started by Charles Darwins. There are many facts found in the ground and has been proven that this use to be far fetched logic is a fact (so we think). The discoverer of evolution is Charles Darwin which created a scientific theory when he had made a trip to a few islands. on every island there were a bird (of the same species) that possessed a different type of beak (which was the result of evolution).on one of the islands this bird had a long narrow beak to get insects out of logs and dirt.

The theory of evolution was formulated by Charles Darwin who first formulated his theory in 1859, defined it as the “process by which organisms change over time because of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.” (Than, 2018) It is natural selection that decides what changes the organism needs so that those changes allow the organism to better adapt to its new environment, it is the biggest evolutionary mechanism. Its purpose is for evolutionary success to promote growing populations of the next generations to come.

Seth Justus English 2 Mr. Johnson Project Eagle Paper on Charles Darwin Thesis Statement: Charles Darwin shaped evolutionary Biology into the way we see it today with his writings on how genetic variations of species between generations, how climate and many other things can cause variations between species, and just his idea of survival of the fittest in The Origin of Species. Primary Source: The Origin of Species The Origin of Species by Charles Darwin, published on November 24th 1859 is considered to be the foundation to evolutionary biology. The Origin of Species introduces the scientific theory that populations of species evolve over long periods of time through the process of Natural Selection.

Darwin infers that the earth was once inhabited by apes, and over time, as the environment progressed, apes ultimately adapted to their environment, and physically evolved into human beings. Stephen Hawking may have shared Darwin’s views as he too supposed that life began when the change in the atmosphere established life form. The article Creation and Reality asserts “in this way a process of evolution was

First off, there are a few different things that give the most obvious evidence to evolution, and that is: the fossil record, embryology, comparative anatomy, molecular biology, and last but not least, biography/direct observation. First, let’s start off with what evolution even is. Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. Next, let’s focus on what the theory of evolution tells us.

Natural selection is the process where organisms become better fitted to their environment and they survive and produce more. Natural selection contributes to the theory of evolution which is when a population gets heritable characteristics over a period of time which sometimes can cause speciation. Three things that support The evolutionary theory are fossils and how they show change, Darwin’s finches, and how organisms can adapt to become resistant. Fossils are a great way to show how evolution happened over the years, for example the pakicetidae. The pakicetidae lived 50 million years ago and is the extinct family of early whales.

As stated before, there are many types of evidence for evolution, lists upon lists that scientists have found over the years. One type of evidence is similarities in DNA sequences, scientists have studied this for a very long time trying to find which organisms are more similar to other organisms in their DNA sequences. Another type of evidence for evolution is anatomical

In 1859, Charls Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. Charles Darwin theory of natural selection is one of the corner stones of morden biology. The concept, published by Darwin and Alfred Russel Wallace in a joint presentation of papers in 1858, was elaborated in Darwins influencial 1859 book on the origins of species. Darwins ideas, along with Adam Smith and Karl Max had a profound influence on 19th century thought. The influence of Darwins theory has spread from evolutionary biology to other disciplines, including evolutionary computation, quantum Darwinism, evolutionary

The notion that biodiversity is the result of dialectical adaptation over time was the cause of much outrage in Darwin’s time. The commonly held views and beliefs were challenged and many academics simply repudiated Darwin’s claims due to ideological objection and the various gaps in the theory. Initially Darwin’s theories were not widely accepted due to various holes in the theory such as the lack of clear gradual fossil records or a clear explanation of how the mechanisms that causes speciation work. Today Darwin’s theory of evolution is widely accepted as scientific fact as there have been a plethora of scientific and technological advancements that have filled various gaping holes in evolution theory, namely the discovery of DNA, RNA and
