Theories on Evolution of Species - 1068 Words

What is Evolution? It â€Å"is the process by which modern organisms have descended from ancient ancestors† [1]. Many great scientists have developed theories to answer the question, â€Å"Where did life, and human beings, come from?† Two major theories of evolution that still exist, and valid today are Charles Darwin’s theory, and Lamarck’s theory. These two theories have many differences, but attempt to explain evolution. Charles Robert Darwin, was a naturalist, who proposed one of the most renowned theories of evolution; the theory of â€Å"Natural Selection†. Darwin published his work of evolution through his book, The Origin of Species and describes the process of evolution as the â€Å"survival of the fittest†. There are four processes to Natural Selection - Variation, Inheritance, Time and Selection. Variation is individuals’ genetic makeup can vary within a population. Variation can occur three ways; sex (the independent assortment of and recombination of genes through meiosis and other processes), gene flow (â€Å"movement of genes from one population to another†)[2] and random mutation. Inheritance is the inheritance of genetic traits from parent to offspring. Time is the timeframe where evolutionary changes, such as speciation, can happen. Selection is â€Å"survival of the fittest†, where the favourable genes dominate the population. The peppered moth is an animal, which follows Darwin’s theory. The start of the Industrial Revolution caused selection pressure on the light coloured pepperedShow MoreRelatedThe Theory Of Evolution And The Origin Of Species1688 Words   |  7 PagesThe Theory of Evolution: â€Å"Grievously Hypothetical† *Rough Draft* First Publicized in Charles Darwin’s On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, The Theory of Evolution has been a widely excepted theory all around the world.

Prior to Darwin’s studies the discussion of the origin of man was dominated by creationism, or the belief that we derive from god, who created us all in his image. For the next thirty years, Darwin devoted himself to researching the long standing question â€Å"where did we come from?† Darwin became the first scientist to present a supported argument for evolution, with his crowned publication, â€Å"Origins of Spec ies†, describing how all species derived from a common ancestorRead MoreCharles Darwin s Theory Of Evolution904 Words   |  4 PagesEvolution is the process new species or populations of living things develop from preexisting forms through successive generations. Some people believe in evolution and some do not. Scientists have found many ways to determine the way that a species can evolve over time. Charles Darwin is just one of these scientists. He came up with a theory that explains how species’ evolve and change. He believed that species change by a process called â€Å"natural selection.† Charles Darwin’s theory of evolutionRead MoreCreationism Vs. Evolution1130 Words   |  5 PagesWhere do we come from? The creation of the world has been told through many different stories, and from a variety of religions across the world. The argument between evolution and creation has been debated back and forth for years. So how do we know which claim is corre ct? Has all life evolved from simple bacteria to all the species that appear today, or did life on earth begin with Gods creation of Adam from dust and his partner Eve from adam’s rib bone.

Both species have opposable thumbs, the ability to use tools, walk on two legs, etc. But, can you considered these two species related? Many scientists argues that chimpanzees and Homo sapiens came from a common ancestor, supported by the theory of evolution. The theory of evolution brought many interpretation from scientists and people. But can you considered the theory of evolution, a fact or fiction? In my opinion, the theory of evolution is considered a fact, supportedRead MoreThe Theories Of Evolution Of The Human Population1045 Words   |  5 PagesThe Theories of Evolution The human population has always wondered where they came from, or how they came to be. Why do they have certain characteristics that distinguish them from other species, or how did they acquire these characteristics? Why do they have similar traits to other species? There are many questions about the existence of the human population that they would love to have the answer to. Unfortunately, there is not an answer that is a proven fact. Luckily, there are theories thatRead MoreEvolution And Evolution Of Evolution1110 Words   |  5 PagesEvolution What is evolution? How did life even come about?

This book was the beginning of what we know about evolution, and it was controversialRead MoreCharles Darwin s Theory On Evolution Essay1074 Words   |  5 Pagesuniverse and Earth? Charles Darwin’s theory on evolution, which is called natural selection, is based on the idea of species naturally adapting to their surrounding environment to better the species chances for survival. Creationism, on the other hand, is the belief that the universe and living organisms originate from specific acts of divine creation. Both are theories on life, and how such life came to be thing we all know.
