Charles Darwin Essay

Darwin was a English naturalist whose scientific theory of evolution of what he called natural selection actually became the foundation of the modern evolutionary studies still today is unanswered with many more theories. Furthermore Darwin actually came up with this scientific theory of evolution by natural section whilst being on his 5-year voyage during 1837-39 however kept this private for some time.

Charles Darwin’s theory was natural selection, the survival of the fittest and the struggle for existence, which had a great impact on selective breeding. Organisms that were well-adapted to their environment had more tendency to survive and reproduce, providing their genetic characteristics for future generations whilst those less-adapted organisms were more likely to be decreased in amount. Charles Darwin’s theory also

In his own time, Charles Darwin was a controversial figure, and although long ago, that same controversy sparks today in the twenty first century. There were many who loved and many who hated Darwin, which has allowed the controversy to expand in recent years to include questions about his role in the development of the evolution theory. The theory of evolution was not created by Charles Darwin; however, through his On the Origin of Species, he logically expressed the theory which ultimately shifted the burden of proof from those who denied it to the supporters of evolution all of which was corroborated by careful observation.

Though Darwin ideas were accepted and due to that allowed for new scientific advances there was some who did not accept his ideas. Darwin’s ideas had offended to the

Darwin, after arriving at the Galapagos Islands in 1831, went to study animals. He ended up studying, 13 kinds of finches, earthworms,

Natural Selection, a key mechanism of evolution is the progressive process by which biological traits either become more or less common in a community or population as a result of inherited traits on different reproductive success of organisms with their environment. Charles Darwin in fact put together an articulate theory of evolution and supported it with a good amount of body evidence in 1859 when he published his book. Natural selection is too however a basic mechanism of evolution like mutation, migration and genetic drift. In order for natural selection to work, Darwin came up with 5 different theories that brought about evolution. The five theories are: evolution, common descent, species multiply, gradualism, and natural selection itself. Evolution is when species come and go through time, while they exist they change. Common descent is organisms are descended from one, or several common ancestors and have diversified from this original stock. Species multiply is the diversification of life involving populations of one species diverging until they become two separate species; this has probably occurred billions of times on earth. Gradualism is evolutionary change occurring through incremental small changes within populations; new species are not created suddenly. Animals and plants of all sorts undergo changes through natural selection. The peacock is a unique animal that stood out to me that undergoes natural selection.

He wrote in his notebook about the conspicuous species he observed and obtained specimens of the unique plants and animals. In the video “Charles Darwin and the Tree of Life” the narrator mentions that a British resident residing in the Galapagos could decipher which island a tortoise came from, by looking at its shell. “If it had a rounded front, it came from a well- watered island; whereas one from a drier island had a peak at the front which enabled it to reach up to higher vegetation.” Darwin questioned himself and wondered if these different tortoises were a different species and if so, how did they evolve to suite their environment.

Charles Darwin believed that all living things come from a common ancestor. For example, Humans and Monkeys have a common ancestor. Charles Darwin studied finches and mockingbirds. He found out about evolution and how it is a population that changes over time. An example he learned is the finch. He found out that there are different beaks for the different finches. An example of an finch is the woodpecker finch which had a longer beak because it had to get the insect inside the tree and has a better chance of survival because it goes high into the trees to get away from the predators.. Which is different than the vegetarian finch had a curved finch for taking berries from a branch and had a less chance of survival because the predators

Darwin begins his introduction by describing how the created his theory of natural selection. He discusses his time aboard the H.M.S. Beagle, and how he observed the species in South America and islands around it and recorded his data. While he made these observations, he began to think about the origin of species, and began to form his theory when he returned to Britain. His poor health and the fact that another scientist was closing in on the theory Darwin had been close to completing pushed him to publish his findings. Darwin was not first scientist to notice similarities between species and notice that species couldn't have been created independently. However, Darwin did notice that the environment couldn’t be the only thing creating adaptations

While on this journey around the world, Darwin noticed that species had different variations to them that, based on the specific location, allowed them to survive in that area. It was this observation that initiated his interest in the particular matter. He believed that the species that he observed, though they were all similar, were able to survive in certain areas due to what he called natural selection. This term basically means that species went through evolutionary changes over time which produced variations within them. These variations added to their ability to aid in their survival. A parent with this variation passed it on to their offspring and so on. This variation added to their abilities and those who did not have this ability would die off while those who did possess it would continue to survive. Darwin concluded that the scarcity of resources in certain areas contributed to these variations. In other words, when an area is overly populated and

• Darwin’s theories created a desire to know more about evolution and natural selection. People are still studying in domains linked with darwin’s theory.

Charles Darwin arrived at his theory of evolution and natural selection and created a societal transformation within the science world. Darwin’s theory of evolution consisted of two main points: different groups of organisms evolve from one or a few common ancestors, and, the method by which this evolution occurs is the process of natural selection. Primarily, evolution is change in characteristics that produces over successive generations, a new version, better suited to its new environment. Types of evolution include adaptive radiation, which defines the evolution where many different 'new species' form from an original species. As the original population increases, it separates from its centre of origin, perhaps because of natural disasters

In 1859 biologist Charles Darwin published On the Origin of Species which laid out Darwin's theory of natural selection. Natural selection stated that an organism which possessed advantageous traits that allowed it to survive and reproduce easier than became more prevalent in the proceeding generations, eventually resulting in a differentiation of species. This is the basis of evolution and is a constantly ongoing process. Organisms that did not possess the advantageous traits were doomed to genetic extinction. This process allowed organisms to adapt and survive.

On September 15, 1835 after a five year trip Charles Darwin arrives in the Galapagos islands on the exploration ship HMS Beagle. The Galapagos islands are in the Pacific Ocean and are close to the equator. There he discovers a many types of finches which have many different shapes and sizes of their beaks. He hypothesized that the finches ventured to the Islands from mainland (South America), and then diverged in form. Then he noticed that because the distance between the islands is too far for the finches to travel, they can not interbreed, because of this the populations on the different island tended to become distinct. He then theorized that since they all came from the mainland, being on the islands means different food sources and competition, and then there was different food sources and competition from island to island. So he concluded from that, that the finches on the island since each one is specially built for what it has to eat on the

Sir Charles Darwin was one of the most well-known and recognised scientists whom dedicated his whole life to researching and proving the theory of Evolution. He believed that all organisms originated from a common ancestor and have evolved slowly over time. Darwin also named a process called Natural Selection to support his theory. Natural Selection can be described as the ‘survival of the fittest’, meaning that the environment selects those organisms that thrive from the available resources and suitable conditions to ultimately reproduce exponentially. The offspring born with favourable variations or differences could help them to obtain resources, find food, avoid predators, resist disease and reproduce. The offspring born with disadvantages may lead to death as they are not strong enough or do not have the traits they need to be able to survive. Darwin was convinced that
