Recommended: Theory of natural selection? essay

In this lab, we explore the effects of natural selection on a snail population in two separate environments. Natural Selection is a theory first introduced by Charles Darwin, who suggested that populations produce a large number of offspring which leads to limited resources for survival. This theory states that individuals who are best adapted to the environment are the ones who survive and live on to reproduce and pass on their genetic information to offspring. The adapted traits would accumulate and change the population over time. The environment determines which traits are most evolutionary desirable to an organism. If a population should move or should the environment change, a different set of traits would be the most advantageous and thus become adaptive. Darwin’s famous finches are a great example of this as it shows natural selection occurring in populations who moved to different environments and then evolved into separate species, each with its own distinguishable beak adaptations. Also, if two populations find themselves in similar environments, it is likely that similar...

    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.

    In Mivart’s Genesis of Species, the author highlights the inconsistencies of Darwin’s natural selection theory. He supports his assertion by emphasizing how species placed in similar environments acquire different traits, questioning the long-term advantages of these evolved traits, and noting the logical inconsistencies of how traits can span in all directions.

    Natural selection is associated with the phrase “survival of the fittest.” This basically means that the fittest individuals can not only survive, but are also able to leave the most offspring. The selection of phenotypes affects the genotypes. For example, if tall pea plants are favored in the environment, then the tall pea plants would leave more offspring behind, meaning that the offspring will carry tall alleles. Phenotypes that are successful have the best adaptations (characteristics that help an individual to survive and reproduce) to their environment. These adaptation arise from the interactions with living and nonliving aspects of the environment. Some nonliving aspects of the environment are climate, water availability, and concentration of mineral sin the

    Evolution in general, is a hard concept to grasp. There are multiple factors that effect the outcome a species, for example: genetics, nurture, nature, and the environment all play an important role. It was once said that species do not survive due to the fact that they are the strongest or the most intelligent, but because that species is the most responsive to change.

  • Animal Overpopulation Essay

    Thousands of animals are put to sleep each year due to not having any available homes for them to be adopted. According to Jennifer Sexton and Tom Warhol in Domestic Animal Overpopulation, “The average female cat can produce two litters of six kittens per year, a female dog can produce one litter of six or more puppies per year, making pet overpopulation a significant problem.” Animal overpopulation is costing money and you can help the pets with spay and neutering programs. A new solution is mandatory contracts for breeders and spay and neuter programs. This paper will talk about spay and neuter programs, contracts for breeders, and why some people don’t think animal overpopulation is a problem. Thankfully there are solutions to this issue of animal overpopulation.

    According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.

  • 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).

    It is important to notice that the opening chapter acts essentially as an introduction to a wider discussion throughout his book. In an effort to give his exploration some order and consistency, Bluestone organizes his discussion under five sections. He identifies five main points, which composes the process of adaptation. Despite these efforts to contain each discussion under such headings, Bluestone’s discussion goes off track during his analysis, which only makes the laws that govern adaptation harder to underst...

    Darwin writes on how a species will adapt to its environment given enough time. When an animal gains a genetic edge over its competitors, be they of the same species or of another genus altogether, the animal has increased its chance of either procreation or adaptation. When this animal has this beneficial variance, the advantage becomes his and because of this, the trait is then passed on to the animals offspring.
