Neil Degrasse Tyson 's Theory Of Evolution

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.

Gould explains how Evolution is a theory and a fact. Evolution is a fact but how evolution happened is a theory. Darwin's theory of natural selection as an example of how evolution happened. Creationists deny evolution. Creationists believes in a supernatural creator of plants and animals. They believe that science would never discover how the creator created creations. Gould believes that Scientific creationism is a meaningless phrase because it’s

Creationism, it is theory that claims every element in the earth, including living species, are all created by the god as the Bible said, which denies the evolutional theory came up by Charles Darwin. Then, since Darwin’s evolutionary theory is testable and make solid predictions whereas creationism cannot be tested nor predict precisely, it has been considered as a pseudoscience. However, recently there is a Ph.D. Biochemist bring creationism theory back to the audience again, his name is Duane Tolbert Gish from University of California. Dr. Duane T. Gish has written several books and articles to support creationism, and the most famous one is Evolution: The Fossil Say No!, which published in 1978. In his article, he denied the evolutionism since he claims there is insufficient fossil evidence to support Darwin’s theory, and which would prove creationism is real.

The late Stephen Jay Gould, a noted paleontologist who once described himself as an “agnostic leaning towards atheism,” wrote the classic treatise Evolution as Fact and Theory for Discover magazine back in 1981. His distinguished career and scientific achievements did earn him respect amongst his peers, but to the general public he is best known for his popular science writings and, to smaller circles, as a champion of evolution. As his treatise was written for a non-academic, science themed magazine, a basic understanding of science, and specifically evolutionary mechanics, was assumed of his audience. The treatise itself is on the often overlapping distinction between “theory” and “fact”; two words, he asserts, that creationists

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 most important evidence of evolution is found beneath our feet. In chapter two Coyne opens up with a quote form Charles Darwin: “The Crust of the earth is vast museum; but the natural collection have been made only at intervals of time immensely remote.” The fossil record provides some of the best evolutionary evidence. Utilizing fossils has been around for hundreds of years. All fossils are formed the same way, needing a specific group of circumstances to occur.

Neil deGrasse Tyson is a contemporary astrophysicist, cosmologist, author, and television host. He is best known for starring in numerous television shows explaining the universe in terms of physics. He states, “During our brief stay on planet Earth, we owe ourselves and our descendants the opportunity to explore — in part because it 's fun to do. But there 's a far nobler reason. The day our knowledge of the cosmos ceases to expand, we risk regressing to the childish view that the universe figuratively and literally revolves around us.” The universe has been a constant mystery and challenge to humankind. Humans wish to understand what is beyond their immediate environment. Cosmology is the study of the universe, more specifically, the origins, evolution, history, structure, and ultimate fate. In Greek, the term “cosmos” means universe, which is the very foundation of the study. Cosmology’s largest critic is Creationism; thus, science and religion battle it out to discover what is true and right in the world. The history of the universe extends past the beginning of humankind and the following philosophers, mathematicians, and astronomers will attempt to provide explanations of what is known today as the Great Unknown.

The opposition to this theory comes in part from those whose religious beliefs are contradicted by it, those who claim that evolution is “just a theory,” and claim it is not a sound science because of the label. To understand that evolution is true and reliable, the definition of the word theory in a scientific context must first be understood. In Richard Dawkins’ “The Greatest Show on Earth,” this is explained, ”The Oxford English Dictionary gives two meanings… Theory, Sense 1:... a hypothesis that has been confirmed or established by observation or experiment, and is propounded or accepted as accounting for the known facts… Theory, Sense 2: A hypothesis proposed as an explanation: hence, a mere hypothesis,speculation, conjecture…” It is proposed in this book that scientists and creationists are using these definitions in different contexts. Creationists use the second sense of the word theory, meaning a speculation of no value, and scientists use it in sense one, that of a proven hypothesis. In science the word theory is surpassed only by the word law in the sense of conveying certainty. In science, a theory is a hypothesis that has never been disproven, such as the theory of gravity. Evolution has been proven many times over through both observation and experiment, which is the reason it is taught in public schools. Though it has uncountable examples, only a fraction will be mentioned. Transitional fossils are one of the major concerns on the part of creationists. They use gaps in the fossils record to argue its unreliability. Transitional fossils are the species that lie in between the transition from one species to its ancestor or descendant. When these fossils are missing, it can seem far-fetched for a whale to develop from a land dwelling dog like animal, but when the fossils in between these two species are discovered, the transition becomes clearer. Though

Some of the major types of evidence that supports evolution are from the similarities that organisms living on distant locations have to one another. Charles Darwin logic when he summarized his findings of five year collecting evidence around the world while he was on the HMS Beagle. Darwin noticed the similarities between animals and plants on the same continent though they were diverse.

The first piece of evidence towards evolution I would like to talk about is fossils. Over the years, we have collected pieces of evidence all across the globe that show us how much our world has changed. The fossil record has allowed us to put into chronological order, which species lived on the earth at what time. We can find a fossils age using the two main methods of either relative or absolute dating. Relative dating is used to determine a fossils age based off of

Overall, fossil records, embryology, comparative anatomy, molecular biology, and direct observation, all support the idea of evolution. Each come into play at different times, but all are needed to back up the idea of

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

Fossils. Paleontologists study fossils using tools such as carbon dating show a pattern and a timeline of emergence supporting the concept of evolution (Khan Academy, 2018). Although there are significant gaps in the fossil records, what does exist supports the theory of

For example, embryos of many animals, from fish to humans each show similarities, which suggest a common ancestor. In humans, it is obvious that embryos begin to develop what would have formed into gills that our ancestors had. Embryos also develop a tail, which by the time they are born it is gone which shows that ancestors were born with tails but we have evolved to no longer be born with a tail. Comparative embryology also shows that many different life forms experience similar stages of development, which points to common origins. Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny (evolution of species). Comparative anatomy has served evidence for evolution, which indicates various organisms share a common ancestor. Comparative anatomy is the first line of reasoning in determining the connection of

Evolution has been debated for many years. Most scientists assume evolution to be true, but it is not officially proven. Evolution is known as “fact and theory,” because it is a fact that organisms have changed over time, but the mechanism that changes those organisms is uncertain. One of the major debates regarding evolution is the belief in creationism. Creationists believe that the Universe and organisms on Earth were all created by a divine power. There are also some theories in which creationism and evolution coexist. One idea is that the divine being who created the world used evolution as a method. Another idea is that science and religion are actually the same thing and religion explains the unknown parts of science. For example, science says that the world couldn’t have been created in seven days, but one of God’s days may not be the same length
