Using Evidence To Support The Theory Of Evolution

762 Words4 Pages

Evidence utilized to support the theory of evolution is provided in sources which include: 1) modern day examples of evolution; 2) the fossil record; 3) homology; 4) biogeography; and 5) molecular evidence (Daempfle, 2016). In this paper, four of the provided sources will be discussed in no specific order. Modern-day evolution provides evidence which shows that species evolve differently while in different environments, whereas different species evolve similarly when exposed to the same type of environment.

As evolution usually occurs slowly over many generations of life history, it is important to know that evolution is a population concept rather than an individual concept. Evidence within modern-day evolution includes common ancestry …show more content…

Geologists are able to track characteristic of populations that change slowly over time or rapidly by examining fossils. Some changes are notably slow enough that they are measured in eons. Therefore, Geologists are able to inspect the fossil layers of the Earth, in order to review the fossil evidence for evolution that supports Darwin’s predictions regarding changes in a species over time (Daempfle, 2016). In addition, fossil records show that prokaryotes did precede all other life and that animal classes developed in the predicted taxonomic ways, consist with Darwin’s theory (Daempfle, …show more content…

Thus, Darwin surmised that a species would have characteristics similar to those of their common ancestor. Scientists have studies homologous structures that have shown through analysis of the fossil record, that Darwin was correct (Daempfle, 2016).

Bones such as the thigh bone or femur were determined to have the same general shape and relatively similar size in various species: whales, humans, birds, and bats, for example. Often, evolution does not change the design in its entirety as life is efficient and it design persists in many species (Daempfle, 2016). In addition, vestigial organs and embryos are also found across different species, further indicating a sign of common ancestry (Daempfle, 2016).

Perhaps the strongest pieces of evidence associated with evolution are molecular evidence (Daempfle, 2016). All organisms have the same genetic to carry out life functions. In addition, the central dogma defines the common on characteristic found in all living species (Daempfle,

As my team and I discovered a new fossil in our excavation project, the unknown site yielded the skull of a mysterious specimen. Our goal as reputable anthropologist was to analyze the specimen to the best of our ability so our team can provide the most probable and reliable taxonomic identification. In order for us to effectively interpret the results our experiment yielded, we needed to review our knowledge in human evolution. The field that uncovers the mystery of the evolution of humans is paleoanthropology, the study of human evolution through the fossil record.

Although he was careful to show respect for Darwin’s ability to see both sides of his own hypotheses, Dr. Whitmore did not hesitate to point out numerous areas where the theory of evolution does not align with actual scientific data. He noted, for example, that Darwin predicted limitless numbers of transitional organisms in the fossil record due to the processes of natural selection. However, significant numbers of transitional organisms do not appear in the fossil record until the Cenozoic Era, which, according to a Creationist worldview, corresponds to the strata laid

Imaara Zuhaire May 1, 2023 Introduction to Human Evolution Professor Robert Scott Fossils are an important tool to help tell stories about the history of the world and humankind. Fossils help answer important questions such as how humans evolved over time, what their lifestyles and diets looked like or where they migrated from. Anthropologists see fossils almost as celebrities because of their rarity. This importance is portrayed through the lens of Lydia Pyne in Seven Skeletons: Evolution of the World’s most Famous Human Fossils. Seven Skeletons is an exploration of scientific and cultural significance of human skeletons throughout history.

This argues that different species adapt to their environment through mutations and this can also explain how a species can gradually evolve. An organism does not evolve in its lifetime, because species evolve as whole through variations. Whether the variation is in color, structure, or a physical trait, they allow us to tell a species apart from others. An example of this can be seen through any species, but Charles Darwin took close interest in observing mockingbirds when he was visiting the Galapagos Islands. The mockingbirds had subtle differences or variations in their color.

Dear Lavon, Have you ever heard about the 5 evidences of evolutions? I’m writing you this letter to help you understand and support the facts about the 5 evidence of evolution. There are 5 evidence they’re fossil record,embryology,comparative anatomy,molecular biology, and biography/ direct observation. The first evidence to be found was the fossil record, the fossil record helps us keep track of where animals that lived on planet earth millions of years ago.

One of the main arguments that Darwinsts use is the argument that fossils are evidence of evolution. I have gathered information from Your Inner Fish and internet sources. I found an article online that says in a nutshell; there 's two lines of evidence for evolution. The first line of evidence concerns the order in which fossils are found buried. Fossils are generally found buried in a sequential order.

On November 5, 1981, the late Colin Patterson, who was the senior paleontologist of the British museum of Natural History in London addressed his fellow evolutionary colleagues in an address and quoted with saying: “One morning I woke up and something had happened in the night, and it struck me that I had been working on this stuff for twenty years and there was not one thing I knew about it. That’s quite a shock to learn that one can be misled so long. Either there was something wrong with me, or there was something wrong with evolution theory .” The theory of macroevolution has been accepted by scientists since the 1800’s, and they claim to have a heap of evidence, but it may not be as strong as they want society to think.

Introduction The theory of evolution is the central theory to understanding biology, it explains why there is so much diversity in all aspects of life and why chemical pathways can be the same in long separated lineages of species (Farber, 2003). Due to the key importance of evolution we have designed our exhibition to encompass all aspects of evolution from the creation of Earth to the present day. Our exhibition will also contain tectonic plate development, changes in CO2 and O2 levels and the development of technology. With evolution being such a key part of understanding biology and science it is imperative that the public have a good basic level of education on the subject. A large percentage of Americans still believe in creationism,

Scientists across various fields of studies with excellent academic achievements voice their unwavering belief in the theory of creation, and they depict multiple experiments and studies to solidify the validity of creationism. Evolution versus creationism is a battle that began long before today’s modern trials and protests, yet the same basic principles still exist. Creationism is as scientific as evolution, and evolution is as faith-based as

BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
