Natural selection: It is defined as the process of natural adaptation to the environment by the species to survive and their existence through the production of offspring. Heritable information is in the continuity of life completely depending on the chromosomal number without any genetic drift. Natural selection operates to select the specific genes for survival and expression in the progeny based on the reproductive ability and selection coefficient. DNA is the fundamental unit of heredity. Chromosomal Euchromatin, heterochromatin together with telomere enable cell division associated genetic recombination of paternal and maternal chromosomes at the time meiosis by crossing over of sister chromatids with chaisma. This DNA contains heritable

    Biological evolution is defined as any genetic change in a population that is inherited over several, successive generations. (R.Bailey, 2014) The changes accumulate and over time a new species is created. One of the basic mechanisms of evolution is Natural Selection. Natural Selection is random genetic variation occurring within an organisms DNA and the beneficial mutations being preserved because they aid survival. (C.Darwin, 1859) Two notable scientists associated with the theory of evolution include Charles Darwin and Jean-Baptiste Lamarck.

  • The Themes Of DNA And Ridley's Genome By Matt Ridley

    1954 Words  | 4 Pages

    The book Genome by Matt Ridley tells the story of the relationship between genome and life by examining the twenty three chromosomes of the human DNA. Each chromosome literally and metaphorically becomes a chapter in the literal and metaphorical book of DNA. In this book of DNA, Ridley examines a particular aspect of the chromosomes chapter by chapter to see how it affects life and humanity’s understanding of life, humans and genetics itself. Although each chapter dives into different aspects of DNA and gathers stories as varied as the genes’ applications, Ridley connects them with important ideas about life and humanity’s understanding of life.

    Biological evolution is a change in the characteristics of living organisms over generations (Scott, 2017). A basic mechanism of evolution, the genetic drift, and mutation is natural selection. According to Darwin's theory of evolution, natural selection is a process in nature in which only the organisms best adapted to their environmental surroundings have a higher chance of surviving and transmitting their genetic characters in increasing numbers to succeeding generations while those less adapted tend to be eliminated. There has been many experimental research projects that relate to the topic of natural selection and evolution.

As the examples given here illustrate, natural selection may take on many forms and give a species better defensive, offensive, or reproductive measures in the struggle for existence, which, though it sounds dramatic and urgent, is nothing more than being able to effectively cope with the external world and reproduce.

  • The Pros And Cons Of Natural Selection

    1633 Words  | 4 Pages

    Natural selection is simple yet complex process that allows species adapt to its environment. Natural selection guides evolution by “sifting out” favorable traits that increase survival for the species. Natural selection is driven by reproductive success. If a species can reproduce and its offspring survive than any traits in its genotype that assisted in its survival will be passed on from generation to generation and ensure that the species will live on. Around the time the Theory of Evolution was suggested, society was very religious and very pressed on the Theory of Creation, so the publication of Darwin’s The Origin of Species by Means of Natural Selection caused a lot of controversy. Darwin gave the world strong evidence that natural selection and evolution played a major role in the development of the species that we see today. Of course natural selection is not the only process driving evolution. In order for natural selection to happen, the species has to have genetic variation. Genetic variation happens because of mutations and recombination of genes. Other processes that contribute are gene flow and genetic

  • Overview of the Importance of DNA

    1575 Words  | 4 Pages

    Discoveries in DNA, cell biology, evolution, and biotechnology have been among the major achievements in biology over the past 200 years, with accelerated discoveries and insight’s over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be the most important and describe their significance to society, health, and the culture of modern life. DNA (deoxyribonucleic acid) is a self-replicating molecule or material present in nearly all living organisms as the main constituent in chromosomes. It encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.

    Inside the cells that produce sperm and eggs, chromosomes become paired. While they are pressed together, the chromosomes may break, and each may swap a portion of its genetic material for the matching portion from its mate. This form of recombination is called crossing-over. When the chromosomes glue themselves back together and separate, each has picked up new genetic material from the other. The constellation of physical characteristics it determines is now different than before crossing-over.

  • Natural and Artificial Selection

    1617 Words  | 4 Pages

    Many scientists in the past, such as Aristotle and Plato, believed that there were no changes in populations; however, other scientists, such as Darwin and Wallace, arose and argued that species inherit heritable traits from common ancestors and environmental forces drives out certain heritable traits that makes the species better suited to survive or be more “fit” for that environment. Therefore, species do change over a period of time and they were able to support their theory by showing that evolution does occur. There were four basic mechanisms of evolution in their theory: mutation, migration, genetic drift, and natural selection. Natural selection is the gradual process by which heritable traits that makes it more likely for an organism to survive and successfully reproduce increases, whereas there is a decline in those who do have those beneficial heritable traits (Natural Selection). For example, there is a decrease in rain which causes a drought in the finches’ environment. The seeds in the finches’ environment would not be soft enough for the smaller and weaker beak finches to break; therefore, they cannot compete with the larger and stronger beak finches for food. The larger and stronger beak finches has a heritable trait that helps them survive and reproduce better than others for that particular environment which makes them categorized under natural selection (Freeman, 2002).

    The textbook defines evolution as the way a species or a population is changing throughout time through the allele frequencies of a gene pool. The gene pool is what makes the species different from others in genetic information carried by the population. The way about the change in species is the explained through the mechanisms of evolution. These mechanisms can be described with these four terms: mutation, gene flow, genetic drift, and natural selection.

    Genes from parents are passed down to their children and this sets up their lifelong development. When a male cell meets with female reproductive cell, they start a process for a new life in a woman’s womb. The sperm has a different copy of the gene and an egg the same and so when they meet, two copies of genes are present and through them a new life begins and it will comprise both genes. From the eyes to the color of the hair, genetics plays a role in a person’s biological make up and development. Genes can predetermine many different characteristics in human development.
