    On the Origin of Species

    English naturalist Charles Darwin wrote the definitive book outlining his idea of natural selection, On the Origin of Species. The book chronicled his studies in South America and Pacific islands. Published in 1859, the book became a best seller.

    English naturalist Charles Darwin developed the idea of natural selection after a five-year voyage to study plants, animals, and fossils in South America and on islands in the Pacific. In 1859, he brought the idea of natural selection to the attention of the world in his best-selling book, On the Origin of Species.

    Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.

    Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

    Darwin chose the name natural selection to contrast with “artificial selection,” or selective breeding that is controlled by humans. He pointed to the pastime of pigeon breeding, a popular hobby in his day, as an example of artificial selection. By choosing which pigeons mated with others, hobbyists created distinct pigeon breeds, with fancy feathers or acrobatic flight, that were different from wild pigeons.

    Darwin and other scientists of his day argued that a process much like artificial selection happened in nature, without any human intervention. He argued that natural selection explained how a wide variety of life forms developed over time from a single common ancestor.

    Darwin did not know that genes existed, but he could see that many traits are heritable—passed from parents to offspring.

    Mutations are changes in the structure of the molecules that make up genes, called DNA. The mutation of genes is an important source of genetic variation within a population. Mutations can be random (for example, when replicating cells make an error while copying DNA), or happen as a result of exposure to something in the environment, like harmful chemicals or radiation.

    Mutations can be harmful, neutral, or sometimes helpful, resulting in a new, advantageous trait. When mutations occur in germ cells (eggs and sperm), they can be passed on to offspring.

    If the environment changes rapidly, some species may not be able to adapt fast enough through natural selection. Through studying the fossil record, we know that many of the organisms that once lived on Earth are now extinct. Dinosaurs are one example. An invasive species, a disease organism, a catastrophic environmental change, or a highly successful predator can all contribute to the extinction of species.

    Today, human actions such as overhunting and the destruction of habitats are the main cause of extinctions. Extinctions seem to be occurring at a much faster rate today than they did in the past, as shown in the fossil record.

    Natural selection is a process by which organisms that are better adapted to their environment tend to D-survive.

    Rationale behind not choosing other options:

    A. Better adaptation to an environment doesn't lead to an increase in the size of the organisms. The organisms rather become sturdy and efficient at perform optimally as per the requirement in the environment for their survival.

    B. Migration takes place to minimize competition for food, shelter, and space in an environment or a habitat.

    C. Organisms that evolve new traits tend to better survive in an environment and natural selection favors such organisms over the inefficient ones.

    A process by which a particular feature of an organism makes it capable of surviving and reproducing better in the surrounding environment as compared to other members of the species is called natural selection.

    Further Explanation:

    The theory of natural selection was given by Charles Darwin in the year 1859 as a means of explaining speciation and adaptation. According to him, natural selection is defined as a principle in which even the smallest variation in an individual’s character is preserved and selected if found to be useful for its survival. The organisms whose characteristics are best suitable for a given environmental condition are likely to survive and reproduce more. This implies that a heritable change in certain members of a species that allows them to adapt to their environment is considered as advantageous variation and are selected as such.

    The difference between artificial and natural selection is that the latter is unintentional in nature. This is due to the difference in the phenotypic characters of an individual with others in the population. The better adaptive characters help individuals to be able to remain and increase their numbers.

    In a population, variation exists among different organisms and between the organisms of the same species. This is because in an individual’s genome random mutations take place often and these mutations are inherited by their offspring. The individuals of a population undergo certain changes throughout their life span in accordance with their environmental conditions. These variations or changes in the traits of an organism increases its chances of survival compared to the individual who is less successful in producing a variation in its genome. This results in the evolution of the population which adapts better to a certain environment and the process is a natural selection where the fittest organism survives.
