Introduction to Evolution

There have been many theories of evolution and how it is brought about and what it is exactly. Charles Darwin a scientist who came up with his theory of evolution and how it works. Darwin felt as though evolution to him was that it occurred through natural selection. Natural selection is the process of only traits that will survive are passed to the next generation. Species selection operates on variation provided by the largely random process of speciation and favors species that speciate at high rates or survive for long periods and therefore tend to leave many daughter species (Stanley, 1975 ). So Darwin believed that the next generations of animals or different species were created by taking only the traits of species

Evolution is something that can be taken into different meanings, from the way you live. Some people can accept evolution and some can’t. The meaning of evolution is the way a different animal or species came to be, and how they are linked to a different of species that all share a common ancestor (an introduction to evolution). There is a lot of evidence to shows that evolution is can be proven like DNA Sequences, Fossil Records, Cladograms, and analogous/homologous structures, because there are so many ways to prove that there is evidence for evolution, but I 'm only going to discuss four of them.

At the beginning of the 1800s, scientists knew of some kinds of fossils, and were very aware of homologous and vestigial structures. Many scientists suspected that some kind of evolution had given rise to living things around them. However, they had no theory to explain how evolution might have occurred. Two scientists led the way in the search for a mechanism of evolution. The first was Jean Lamarck. The second was one of the greatest figures in biology, Charles Darwin.

Define evolution? A slow change of something into better form. The word evolution means change, and the process of evolution reflects this definition as it applies to populations of organisms. Biological populations are groups of individuals of the same species that are sub-divided from other populations by geography and are somewhat independent of other groups. Biological evolution, then, is a change in the characteristics of a biological population that occurs over the course of generations. The changes in populations that are considered evolutionary are those that are inherited via genes. Changes that may take place in populations due only to short-term changes in their environment are not

A way we know evolution is real, is by looking at the bones of the creature. If you look at the bones of many creatures like us humans, monkeys, bats, and even whales. We all have the same bone structures. We all have the same amount of bones on the hands, fins, and wings. This leads to the theory that we might have had a common ancestor.

Gregor Mendel is usually known to be the father of modern genetics. But farmers already known for centuries that crossbreeding of animals and plants have favorable trait outcomes. Mendel’s pea plant experiments were conducted between 1856 to 1863 established many of the rules of heredity. Mendel did his experiments at the University of Vienna, Public university in Vienna, Austria.

organisms born with the advantages will have a better opportunity to survive and reproduce. During reproduction, the advantages may be inherited by the offspring. When this process occurs to many individuals within a species, the organisms with the advantages will have a higher frequency. This will be higher than that of the organisms without the advantages. Eventually the organisms will become an evolved population. The other population may survive or become extinct (“Judgment Day: Intelligent Design on Trial” 7). The first scientist to introduce the theory of evolution was the Greek Anaximander in 520 BC. When the idea was proposed, it was not called evolution. Anaximander suggested that life began as slime and moved to drier places to develop. Until the nineteenth century, people thought only thought that each species was miraculously created out of nothing. Today, this idea is known as evolution. The main researcher of evolution was Charles Darwin. He was not well respected among others. He proposed his theory of evolution in the nineteenth century. He proposed that in each generation, a species contains individuals with characteristics varying slightly from average. These differences may be minor, but some give those individuals a better chance of surviving and reproducing. This will pass on the advantages to the offspring. That species may become extinct. Nevertheless, its

Charles Darwin and Alfred Wallace like so many of their predecessors made observations of natural phenomena that inspired proposals of how life on earth evolved, unlike others these men formed plausible explanations of how the changes in populations occurred without having any knowledge of Mendelian genetics which was presented in 1868, and provided the micro-mechanism for evolution that Darwin could never explain with his theory of Pangenesis. Rather, based solely on the observations each made over time observing different species of populations around the world, both men were able to pen the ideals that would serve as the foundation of the modern theory of evolution.

Natural selection, a term often used in relation with the concept of evolution. Being as such, ones’ perspective is often led to take sides on a matter that they know little about. One side states that such a concept is full of lies and seeks to throw you from the path of belief. The other says that it proves that man came from a simpler being and that the supernatural is non-existent. Being someone of Christian faith, I was led down the path of the former. It is in my nature, however, to not blindly accept what someone has told me on the sole basis that it is what they believe. So I looked for myself, to come to my own understanding, and what I found led me to reconsider everything I had learned that had fallen onto this “two-path system.”

Charles Darwin broached the theory of natural selection in his book the Origin of Species, which has been considered the basis of evolutionary biology to this day. Natural selection is when populations of a species evolve over the course of many generations. Darwin believed that species were not created separately, but instead, species were derived from one another. In other words, the evolution of species creates many variations among creatures, and this is because all of those species came from a common ancestor, and characteristics changed to increase the species chance of survival.

In the year 1859, Charles Darwin developed the theory of evolution and since then, scientists globally have been studying and trying to figure out exactly how we arrived on this planet. 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.

Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for

Evolution is the spontaneous change in the heritable traits of a biological population over many successive generations. Charles Darwin designed the scientific theory of evolution through natural selection. Evolution by natural selection was a process that was properly demonstrated by the observations. The observations reflected that more offspring are produced than those that end up surviving (Darwin, C., & Wallace, A. 1958).

Together with Alfred Russel Wallace, they introduced a scientific theory that branched patterns of evolution, resulting in a process called natural selection.

Through research it has been determined that evolution is a part of nature, and organisms become more complex over time. As organisms become more complex their characteristics begin to change, and aspects that are beneficial for their survival become prominent in their offspring. However, characteristics that are not beneficial to their survival begins to fade as organism evolve. From this arise Charles Darwin’s theory that evolution occurs because of natural selection, expressing that organisms with the best characters will have a higher survival rates and have the ability to pass these characteristics to their offsprings.
