Why are the same animal species so different from one continent to another? That is a question that Charles Darwin asked himself. Charles Darwin was an English naturalist who studied evolution through animals during a five-year expedition around the world in the 19th century. He explained all his discoveries and investigations in 1859 in a book named “On the Origins of Species” and he also published in the same year his Theory of Evolution by Natural Selection. Some of the animals that Darwin observed were marine iguanas, large tortoises, sharks, rays, fur seals, sea lions, and 26 distinct species of birds.
Now, I am going to explain briefly the Theory of Evolution, Darwin’s book “On the Origins of Species,” and Charles Darwin discoveries. Evolution is the heritable physical or behavior traits progression or changes over time. Animals change when compared to their ancestors that lived before them. Some heritable changes happened because of their environment, only those animals that adapt to their environment will survive. Charles Darwin books “On the Origins of Species” and the “Theory …show more content…
Out of the 26 species of native birds discovered by Darwin 14 of them make up a group known as Darwin’s finches. This group of animals was an example of evolution. For example, the marine iguanas in the Galapagos islands discovered by Darwin had physical traits different from those on the continent because of isolation and they had to adapt to their environment. These characteristics were heritable allowing them to survive. Survival of the fittest is the capacity that an animal has to adapt to their environment to survive and procreate. Organisms have to adapt to environmental changes over time in order to survive. The physical or behavioral changes that improve the chances of survival of an animal are the heritable traits. This is called natural

Charles Darwin Research Paper

...Evolution is the belief that all organisms evolved from other organisms in order to adapt to their environments. Scientists like Charles Darwin had many theories and predictions about evolution that helped shape the knowledge we have today. Darwinism is the idea that the strongest of a group will survive. Scientists know these changes happen through evidence found in living things, DNA, fossils, embryology, and comparative anatomy. Charles Darwin was know as the father of evolution because of his discoveries. He had beliefs of natural selection or the idea that organisms adapt to their environment and have offspring that adapt also. “Scientists comparing the genomes of members of the three domains of life—archaea, bacteria, and the eukaryotes...

Charles Darwin Research Paper

...Charles Robert Darwin was born on February 12, 1809, in The Mount, Shrewsbury, England to Robert W. Darwin and Susannah Wedgwood. The Darwin family was rich, and Charles grew up in the large house called The Mount with 4 older siblings and 1 younger sibling. His early education consisted of lectures by his older sister, Caroline and a small day-school that he was sent to after his mother’s death in 1817. Charles already had developed a love of natural history and collecting by the time he was sent to a school in Shrewsbury in 1818 at 9 years old. “Nothing could have been worse for the development of my mind than Dr. Butler's school, as it was strictly classical, nothing else being taught except a little ancient geography and history.

Comparing Darwin and Alfred Russel

...Introduction Charles Darwin born 12 February, 1809 was an English geologist and naturalist. Alfred Wallace born 8 January 1823 was a British explorer, naturalist, geographer, biologist and anthropologist. Darwin and Wallace are highly regarded for their significant contributions to the theories of evolution. It is very important to compare the individual lifestyles, contributions, and beliefs of Darwin and Wallace in order to develop a clear and comprehensive understanding of their concepts of natural selection in evolution. According to Janet Browne (2010) in her biography of Darwin, she describes the similarities in the life experiences of Darwin and Wallace that led them to independently arrive at the theory of natural selection. Both Wallace and Darwin were inspired by the readings such as Charles Lyell and Thomas Malthus. Browne notes that, “Even so, the parallels between Darwin’s and Wallace’s ideas are no less remarkable for their cultural symmetry. Their similarities are further demonstrated by them sharing similar geographical exploration and travel experiences and their mutual appreciations of their marvels of nature and overwhelming desire to comprehend them…” (Browne 2010: 357). The two theorists examined the concepts of natural selection independently until its publication. By the 1958, Darwin had already developed his idea on natural selection but had not published it as he was still collecting more evidence. After his previous research had been destroyed in...

The Essence of Darwin

...Charles Darwin was born on February 12, 1809, in Shrewsbury, England and died at the Down House in Kent on April 19, 1882. He was born to Robert and Susannah Darwin. Robert was a successful physician whose father, Erasmus Darwin, had also been a physician but had made his name as a poet of the natural world. Susannah Wedgwood came from a family of potters; her father, Josiah Wedgwood, had made a small fortune making high-quality pottery. Both sides of Darwin's family were liberal in their politics and indifferent in their religion. Darwin spent his childhood playing at The Mount, the Darwin home and estate in Shrewsbury. He was schooled at home by his sister Caroline until he was eight years old and Susannah died. He then spent a year at a day school and transferred to a boarding school, the Shrewsbury School, only a mile away from The Mount. There he studied, getting acceptable but unremarkable grades, until age sixteen, when his father sent him to the University of Edinburgh to study medicine. Darwin focused on collecting, hunting, and naturalizing instead of medicine. It was there that he first learned to study and collect beetles. The marine biologist Robert Grant took him under his wing. After two years, it was obvious that Darwin would not become a doctor, so with the help of his father Darwin transferred to the University of Cambridge to study for the clergy of the Anglican Church. There he became friends with the older botanist John Henslow. Soon after graduating...

Theory of Evolution

...Theory of Evolution Charles Darwin was a British Scientist who lived from 1809 to 1882. He laid down the foundation of modern evolutionary theory with his concept of the development of life through the slow working process of natural selection. Darwin started to make notes about this theory in 1836 and in 1838 he had arrived at a sketch of a theory of evolution through natural selection. It was not until 1858 that his theory was first published in a paper. Darwin’s theory states that as plants or animals spread to new areas, or as the conditions change different variations would be favored in different places. This would mean these variations would spread through the populations of the plants or animals. Over time this would finally lead to a development of new species. This theory was explained in the book ‘The Origin of Species’, which describes his studies on the Galapagos Islands in the Pacific Ocean. He noticed that the species on the islands varied slightly from each island and were adapted to local conditions. The reaction to this theory was immediate. Biologists argued that Darwin could not prove his hypothesis. Others criticized his ideas of variation and how he could not prove how these variations came about or how they were passed on. This part of his theory was not answered until the birth of modern genetics in the early 20th century. In fact many scientists had doubts about this theory for 50-80 years. The most publicized attacks came from religious opponents who...

Evolution Versus Creationism

...The debate between evolutionism and creationism began thousands of years ago and the battle between the two streams of thought continues to this day. While creationists believe in a god who is the absolute creator of heaven and earth less than 10,000 years ago, evolutionists believe that the universe began billions of years ago with life started as just a single cell bacteria evolving slowly into everything we see today. “What’s the difference between creationism and evolution?” Charles Darwin’s work on evolution is the most recognized throughout history and the evidence that he discovered supporting evolution changed how many people viewed the history of our universe. His main research project was on a process called natural selection, the idea that survival of the fittest has been a main determinant is shaping how the earth and all living things appear today. Charles Darwin discuses this idea of Natural Selection in his essay “Natural Selection”, detailing evidence supporting his theory. This paper will discuss Darwin’s essay but will also go into further detail of his discoveries, other evolutionary milestones and finally comparing and contrasting the evolutionary argument to the creationism point of view. The idea of evolution first came about in the 1600’s when European naturalists started to question the current theories about how our universe was created. In 1666 the first evidence of evolution was discovered when a couple of fishermen caught a shark. On inspection they...

The team will describe the properties of life on Earth and explain the theories for the genesis of life, including the theory of natural selection. Members will provide a brief description of the evolution of life and include a geological timescale that describes specific eras throughout the previous three billion plus years. The team will assess the possibilities of extraterrestrial life, and results will be presented. Describe the properties of life on Earth Properties of life on Earth are what define the word life. The properties of life consist of cells and reproduction, responses to the environment, growth and development, and evolution. Every living thing is collected through cells which make tissues and organs that make a living organism. All living organisms can produce such as humans, animals, bacteria, and plants called asexual reproduction. The responses of the living in the environment are through any changes occurring in “light, sound, heat, and chemical contact” through “eyes, ears, and taste buds” (Cliff’s notes, 2011, para. 3). Behavior is one way that all living organisms changes through the environment such as the food chain for one’s survival. Growth and development of an organism takes in all substantial amount of information through energy of building...

Life Span Perspectives Paper

...Life Span Perspective Paper Kyla Rash University of Phoenix Life Span Human Development Psychology 375 Professor Kathleen Phelps March 05, 2012 Life Span Perspective Paper No one brought evolution to light like Charles Darwin. His book, titled On the Origin of Species, offered compelling evidence for evolution within species and drew in large amounts of controversy. This controversy led to more and more field work and observations of nature. Eventually, Darwin’s research and studies turned to people and the study of the human life span (Beddall, 1968). The study of the human life span gained momentum in the years that followed the publishing of Darwin’s famous book as psychologists around the world developed different perspectives and theories regarding life span. The following examination focuses on explaining the life span perspective of development, summarizing two different theories of life span development, and offering an explanation to how heredity and the environment produce differences in overall development. The study of human development centers on how a person changes over a lifetime. A person starts life with the birth stage, and then moves through infancy, adolescence and puberty, adulthood, and finishes with death (Berger, 2008). Berger (2008) describes these changes as being linear, gradual, predictable, and sometimes steady. During their life spans, humans learn to communicate, work together, experience emotions...

Darwinism:

...for society both culturally and scientifically. For the first time in history a theory was proposed that offered a plausible mechanism for evolution. This paper examines the science behind natural selection as well as the impact Darwin has had on modern evolutionary paradigms. Specifically it poses two questions: (1) How did Darwin formulate his ideas about natural selection and evolution? And (2) Is natural selection still fundamentally valid or have we moved into a new evolutionary paradigm. Pre Darwin. Every scientific field has an earlier paradigm as scientific cannons change through the process of time. Before the advent of Darwin and his ideas about “natural selection” human evolution was perceived quite differently. During the Medieval Ages the predominate field of thought was in the “Great Chain of Being.” A structured hierarchy that believed everything had its place in a divinely inspired universe (Suber, 1997). An objects place on the “evolutionary” chain depended on the amount of “spirit” or “matter” it contained, less “spirit” and more “matter” placed it further down on the chain. Ideas such as “spontaneous generation,” which stated that organism could arrive fully formed from inorganic matter only served to enforce Christian ideals of divine inspiration and hinder any kind of true scientific research. (Evers, 1999) Carolus Linnaeus (1707-1778), known as the father of taxonomy, was the first scientist to use empirical evidence in support of a hierarchal...

Creationists vs Evolution

...of a church in the community. I was taught the bible and the book of Genesis. The different beliefs that were instilled in me were to believe that God created man and woman. In evolutionary or ecology classes, we are introduced to the theory of where man came from amoeba-like organisms, or even that we evolved from apes. How did life of origin arise? The components of evolution might explain how, but Creation gives a reason to believe why. Origin of life’s existence, as well as age of the earth is a question that is looked under a microscope and probed through both biblical theories, as well as scientific. Looking at difference evidence, acceptance of creation is growing even in spite of scientists trying to prove evolution. Within this paper, there will be different pieces of evidence and facts supporting each theory and there will be an argument, within my conclusion, on which theory I support. The theory of creation can be explained through various books in the bible. Creationists use the Bible as the truth for which they believe the origin of life came into existence. In bible studies and bible school, we were taught that God took clay from the ground which he shaped to a man that he called Adam. A verse in the King James Version, of the Bible, mentions “and the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.” Then, the Lord made a garden as Adam’s place of residency. There are pictures of beautiful...

Galileo

...Galileo "Whereas Galileo spent his last days under house arrest and was formally condemned by the Church for his scientific views, the elder Darwin was widely respected by the Anglican Church and was buried at the Westminster Abbey, an honor reserved for only the most illustrious personages of Great Britain. The reason for the two scientists' very different fortunes is simple: Galileo couldn't prove the Copernican hypothesis but Darwin was able to demonstrate the truth of his theory of evolution." In the world of Galileo proof was what was needed to succeed with a scientific hypothesis. In the world of Darwin proof was not needed for a scientific hypothesis to succeed. There were many differences in the worlds of these two great scientists that lead to the reaction to their respective scientific hypothesize. It was not their beliefs alone that led to their peer's views it was also the way each of them conducted themselves. Galileo worked his way to become a respected scientist by most of the intellectual community but he was also despised by many because of his background and because of his attitude towards others. Darwin was well respected by the intellectual community, but the difference was the way they conducted themselves when they were dealing with their hypothesizes. Galileo's Hypothesis Galileo was well known for standing up for what he believed in and pushing the things he wanted. He was constantly writing letters and engaging in debates over...

Creationism vs. Evolutionism

...only consider the evidence. Through my research I hope to uncover that very evidence to show those who still doubt the real truth. Creation and Evolution are two major beliefs that people follow as a guideline. The two philosophies have different effects on our lives and the make-up of who we are and what we believe. Creation is a belief followed by many people and generally speaking the Holy Bible serves as a guideline and a set of instructions to show how the earth was formed and to guide us through life. Science backs up this Holy Book it is a very reliable source of the history of the world. There are many questions in life that man has always longed to find the answers to and the questions are: Who am I, why am I here, how did everything get here, and where will I go when I die? Well if you believe in evolution then you came from non-living material that all came together from the big bang. There is no purpose to life, you have no one to answer to, so if it feels good than do it and when you die then you will be recycled into a plant. We supposedly came here by chance through millions of years of evolving from a rock. In Creation, an all-powerful creator created you, life is a stepping-stone to get to heaven; there are consequences to what you do, rules to follow and someone to answer to. There is an afterlife for all people either heaven or hell. Could have much of the debate been avoided if it wasn’t for one man, Charles...

Evolution

...Are Modern Humans Still Evolving?In the year eighteen fifty-nine, Charles Darwin published a book which he called “The Origin of Species”. In this book Darwin theorized that populations evolve over the years through a process called natural selection. Darwin realized that in a population, more individuals were born than could possibly survive, he also recognized that the individuals that survived and reproduced were the ones with some sort of competitive advantage over rival animals, therefore they were more likely to pass their useful traits down to their offspring (Darwin, 1859). As this process of natural selection occurred for millions of years, these desirable traits that were once only prevalent in a few individual animals became common traits for entire species (Winston, 2009). There are countless amounts of evidence that suggest that humans owe their existence to evolution, however, many people are skeptical as to whether or not it is still occurring, and whether or not it is happening in the same way. Some scientists hold that the human race has reached “its biological pinnacle and is no longer capable of changing” (McKie, 2005, ¶1). Alternatively, some experts believe that humans are evolving faster than ever (Sample, 2007), and others believe it is still happening, just on different terms. There has not been any deciding evidence as to whether or not humans are still evolving, however, saying it isn’t happening is a very difficult position to defend. Gene mutations...
