Organic Evolution Essay

Charles Darwin, a naturalist born in 1809 England, traveled around the world on the HMS Beagle from 1831-1836 (Desmond). He made observations on land for three out of the five years he traveled around the world; his most significant findings were recorded on the Galápagos Islands. The most crucial evidence of evolution, a theory that Darwin is known for, consist of the different species of Galapagos tortoises and finches that Darwin observed. He noticed that depending on the different islands similar finches had different variations of beak size and shape. To add, he observed that the tortoise's shell shape and neck length varied based on which island they resided on. Darwin made the observation that depending on each island, which had different

What is evolution? Evolution in modern terms is fairly easy to understand. Evolution is the theory that life on earth began with a single celled organism that lived more that 3.5 billion years ago that slowly evolved into

Charles Darwin (1809-1882) was a British naturalist who became famous for his theories in evolution. He believed all species evolved form a common ancestor and that evolution happened through a process called natural selection, which meant survival of the fittest. In the BNW, the different castes of people were made from a common ancestor (a single individual). Thus, creating hundreds of his or her clones. Since the directors believed in survival of the fittest, they made the best kind of people so that they may live long in a specific environment.

The documentary, “Darwin’s Dangerous Idea” tells the story of Charles Darwin’s conception of his theory of natural selection, and how it explains the evolutionary process and species adaptation. The story begins with a brief overview of his 5-year stint on the HMS Beagle as the ship's naturalist, during her South American voyage. The film shows how Mr. Darwin collected fossils and many species of animals and birds from many different regions especially the Galapagos Islands. It portrays Mr. Darwin’s return to England and his struggle between the mainstream religious beliefs and his personal beliefs of how different species came to be. Additionally, the documentary covers his presentation of fossils and ideas to the scientific community,

Darwin’s theory of evolution was along the lines of all life being related- each descending from a common ancestor. His theory presumes the development of life from non-life and suggests purely naturistic

Evolution is when an organism or something evolves over an extended period. An example of evolution would be humans because it took a long time for early humans to evolve into modern humans.

Darwin was the British naturalist who became famous for his theories of evolution and natural selection. Like several scientists before him, Darwin believed all the life on earth evolved over millions of years from a few common ancestors. From 1831 to 1836 Darwin served as naturalist aboard the H.M.S. Beagle on a British science expedition around the world. In South America Darwin found fossils of extinct animals that were similar to modern species. On the Galapagos Islands in the Pacific Ocean he noticed many variations among plants and animals of the same general type as those in South America. The expedition visited places around the world, and Darwin studied plants and animals everywhere he went, collecting specimens for further study.

The word evolution means the process of change over a period of time. For example: plants and animals evolve over time by their genetic system allowing them to adapt to different changes in the world. The theory of evolution states animals, insects, plants, humans, and etc are all from a one-celled ancestor. A bad example of evolution is having a bad diet, which does not pass on to your next generation.

Darwin wanted to further his studies in plant and animal life, and he also became interested in the similarities of plant and animal species to those of the human species. He noticed that humans too also had to develop new characteristics that would help them adapt to their environments. This made him want to look further into where humans came from and also question the idea of creationism. He argued that men are animals because they have to adapt to their surroundings just as animals do. He suggested that the stronger animals have a better survival chance and they produce offspring that carry this trait. A whole new population of species can derive from these offspring and traits that have evolved from older generations and species. This became known as Darwin’s Theory of Evolution.

When Darwin traveled over to the Galapagos island he traveled on a ship called the HMS Beagle. Darwin traveled to the Galapagos island to get information about evolution with the animals there. When he was there he observed tortoises, when he observed these animals he got a understanding of evolution over time. He saw that the tortoises in the area with food low to the floor had a flatter shell and a short neck, but when he observed tortoises with food high up he saw that the tortoises had a long neck and raised shell. Over time the tortoises evolved she they can survive in their environments. When he was their he wrote a book called the Darwins book on the origin of species. The information that he wrote about was information about species that were not fixed but could change over time by natural causes.

In 1837, Charles Darwin was traveling aboard the H.M.S. Beagle in the Eastern Pacific when he stopped on the Galapagos Islands. There, Darwin found a wide array of animals including the Galápagos finches. The differences that he uncovered between these animals sparked Darwin’s interest; he had never before seen nor attempted to understand the similarities and differences inherent within these species. Examining each and uncovering the probable reasons for their distinctions, namely their differing needs for adaptation, Darwin constructed his theory of natural selection. From his observations on the Galapagos Islands, Darwin continued developing his research into eventually what became known as the Origin of Species, published in 1858. In this book, he asserted that these animals and differing species did not just appeared out of thin air, but rather had evolved from other species through the process of natural selection. Yet, his scientific findings were not accepted by the general public when first published, nor long after. Instead, they sparked a great uproar and criticism, since for most people accepted the theory of the Creation, the belief of divine creation, as the way people and species appeared on earth. His findings, so contrary to the then accepted norm of creation, were met with hostility and resentment by many who considered his work

Previously, he had been inspired by Charles Lyell’s Principles of Geology, which stated “present conditions and processes are clues to Earth’s past history.” While on the Beagle’s journey, Darwin sent home a total of 1,529 species that had been maintained in spirit as well as 3,907 desiccated specimens with labels (Biography Online). A breakthrough in Darwin’s studies was when he noticed certain forms of organisms subsist in particular areas, as well as that a wide variety of organisms had previously gone through changes that enabled them to stay alive in their particular environment (Notable Biographies). For instance, he studied the Finch in the Galapagos Islands and noticed that there are over twelve different forms of this one bird. These bird’s beaks were different sizes and shapes, depending on what food was available in their particular area. The animals on the Galapagos Islands showed many similarities to other animals in other parts of the world (Biography Online). Between the discovery of the different Finches along with the similarities of animals from other locations, he began to wonder if there was something more to earth’s history. These observations would later lead him to his theory

Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.

The definition of 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,¨ (Dictionary.com, 2018). Although, the actual definition is hard to comprehend. Some consider Evolution to be a somewhat ridiculous topic that is far from true. Though others believe that, ¨Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology,¨ (Than, 2018). The main idea of Biological Evolution is that all life on Earth share a common ancestor. The term is a way of understanding life.

Evolution refers to "change over time". In terms of physical anthropology, evolution is changes over time in living organisms. This means that living things have passed their traits from one generation to the next. There are very little changes that occur with each generation, but over time these changes accumulate in each living organism. It is believed that all life on Earth has common ancestry that lived more than 3.5 billions of years ago (Park, 2008).
