Introduction
There are two theories of evolution Charles Darwin’s theory on how animals evolved over time eventually turning into what we are today and Lamarck’s theory on that how animal’s characteristics can be passed on their offspring. These two theories from the 1800’s differ from creationist theory and indigenous theory because they both evolve where creationist theory and indigenous theory don’t evolve
Darwin’s theory of evolution
Darwin believed that the desires of animals have nothing to do with how they evolve, and that changes in an organism during its life do not affect the evolution of the species. He said that organisms, even of the same species, are all different and that those which happen to have variations that help them to survive in their environments survive and have more offspring. The offspring are born with their parents' helpful traits, and as …show more content…

Unlike most other people at that time, Darwin and Lamarck both thought that life had changed gradually over time and was still changing, that living things change to be better suited and adapted to their environments, and that all organisms are related. Darwin and Lamarck also agreed that life evolved from fewer, simpler organisms to many, more complex organisms.
The theory of evolution that has the most convincing evidence
The theory of evolution that has the most convincing evidence is Darwin’s theory of evolution. Darwin’s theory makes more sense and is more believable. However, I believe Darwin’s theory over Lamarck’s theory because Lamarck’s theory is too childish, thinking about how human appendix and little toes are gradually going to disappearing whereas Darwin’s theory is more believable where individuals that are not so well adapted to the environment slowly die

Charles Darwin, Alfred Wallace and Jean-Baptiste Lamarck all contributed to the Theory of Evolution that we have today. Through collecting specimens and results, these three men all came up with slightly different theories to support why evolution happens. Charles Darwin was an English naturalist and geologist in the mid-19th century, where he developed his theory of “modification by descent” later known as evolution. Darwin’s theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual’s ability to compete, survive, and reproduce. This theory was supported by many forms of evidence including Darwin’s study of both finches and barnacles.

One of the most noticeable period for fossils was during the Cambrian Explosion that occurred around 540 million years ago. This marks an important history of fossils and species on earth as the Cambrian Explosion, also known as Cambrian period was when most major species started to appear on the fossil records in which it formed a diverse range of fossils. This however, challenged Darwin’s theory of evolution as it was when different kinds of animals and species appeared on Earth without further evidence of other ancestries species (Switek, Brian). Even so, most still believe that the Cambrian explosion was only an unusual occurrence, and fossil records are still consistent evidence for evolution. This then leads back to how different species now resembles species from the past, and by relating this to our unit focus, it might be because of natural selection.

BSC 1020 – Reflection Paper Unit G Evolution and its Processes This unit covers the theory of evolution, its mechanisms, the modern synthesis of genetics and evolution, and classification of species. The first chapter describes the history involved in Darwin’s theory of evolution. It talks about the evidence that supports evolution like the fossil record, biogeography (geographical distribution of species), comparative anatomy, comparative embryology and molecular biology. These collections of evidence help explain how species evolve from a common ancestor with gradual changes over time due to natural selection. Natural selection states that certain traits of an organism inside a population are better for adapting to the environment.

This process was called natural selection he claimed that it was the basic mechanism that had brought about the diversity of the life on earth. Since the late 1800’s the theory of explanations of how evolution works had become more a theory of evolution. As more explanations (evolutionary theory) became accurate, the observations began to accurate, they began to explain the facts, that these facts control the theory, not the other way around.

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.

In the 1900’s, discoveries in genetics and developmental biology were used as evidence for Darwin’s theories of evolution that regarded natural selections as unimportant; because there were more discoveries than just natural selection that were important ("What Did Darwin's Discoveries do.”). Darwin’s theories again became the dominant influences in evolutionary biology in a form called Neo-Darwinism; the genetic origin of variation within species and for how species are formed (“Darwin, Charles Robert.”). Neo Darwinism introduced the connection between two important discoveries; the units of evolution (genes) with the mechanism of evolution “natural selection” ("Neo-Darwinism"). He also showed that living things commonly produced many more

There is competition between all species when it comes to resources, and the ability of whether or not they will survive depends on a variety of factors, some include coloration, speed, or ability in vision. The information from his insights led to Darwin’s term of natural selection. Darwin never saw natural selection occurring during his lifetime but doctors in today’s world can view natural selection in the medical labs by looking at virus’ and bacteria growing and living in human

Due to the aforementioned factors, we are tempted to see the species of today as a monument of the theory of evolution, but it actually undercuts the facts of evolution. Furthermore, a number of misconceptions have erupted throughout the years for the sole reason of not having an appropriate explanation for the facts of the theory of evolution. We are forced to accept wrong notions for us to be able to fully understand the said

In addition, when Darwin was around twenty two years old he was invited to a five-year voyage. What no one knew, was that this voyage would later become one of the key experiences for the development of his ideas and thoughts about the natural life. During his voyage, Darwin developed the scientific theory of biological evolution, which explains how modern organisms evolved over long periods of time through descents with modifications from common ancestor (3). To understand this concept better, descent with modification is the fact that when parents have children, those children often look and behave slightly different than their parents. Additionally, the idea of a common ancestor is the idea that all living things are related because they descend from a common ancestor (6).

Lamarck's theory had been solely based off how organisms change within their lifetime, and they pass changes on to their offspring, whereas Darwin's theory was based on natural selection, which states organisms possessed variation. These variations tend to cause some organisms to survive and reproduce more than others. Darwin's theory was more widely accepted because he provided more evidence to support it, while Lamarck's theory states organisms become more complicated overtime, which does not account for simple organisms. Through observing human activity, we can conclude that Darwin's theory is more realistic. If a human were to get an ear piercing, that wouldn't cause their child to be born with a piercing.

In Introduction to Evolutionary Biology by Chris Colby, the author’s purpose was to explain the basics of the theory of evolution and correct the many of the misconceptions. The main parts are the meaning of evolution and the misconceptions. The meaning of evolution according to Colby is a change in the gene pool of a population over time. The first misconception is that evolution can occur without morphological change and morphological change can occur without evolution. The second misconception of evolution is that natural selection and evolution are the same thing.

Charles Darwin and Jean – Baptiste Lamarck are two of the earliest scientist known for their distinct concepts of evolution. Although both concepts aimed to explain the complexities of evolution, they each take a different approach. Darwin approached evolution through his views of natural selection, while Lamarck approached it through his model of acquired Characteristics. Darwin’s natural selection referred to survival of the fittest. In organisms some variations are better adapted to their conditions of life than others, and, on average, the favorable ones are preserved while the others perish (Holmes.,1948).

What question were you trying to answer and why? Darwin believed that over long periods of time, that the creatures we have today are evolved versions of their ancient ancestors. This is known as Evolution and descent through modification. In the principle of descent through modification, each living species has descended with changes from other species over time.

Introduction The theory of evolution has been discussed, evaluated, and researched many times since the theory was first brought to light. Darwin’s theory of evolution is said to be divided into two parts, common decent and natural selection (Bouzat, 2014). Many research papers agreeing with Darwin’s theory comment on the diversity of a species and how they have descended from one common ancestor. Natural selection is a process in which species that are better adapted to the environment tend to survive and reproduce (Dictonary.com).
