Persistent Pests

In the 1960s, the World Health Organization (WHO) began a campaign to eradicate the mosquitos that transmit the disease malaria. Before that an organization in Southern Africa had produced a poison to kill these mosquitoes but it wasn’t completely successful. The produced poisons by the WHO kills most members of the insects population leaving only the resistant individuals to reproduce with new genes that somehow enable them to resist the chemical attack. The problems such insects pose are just some of the many ways that evolution has a direct connection to our daily lives considering the adaptations in local environments.

    Widespread disease has been a great cause of rapid mortality rates throughout history. As some diseases vanish or become less prominent in society, cultural and biological anthropologists have been able to conduct research on to how human adaptation and resistance to disease occurs. Based on interconnectedness of aspects such as economy, population distribution, horticulture, environment and anatomy, biological anthropologists and cultural anthropologists are able to draw connections and prove how humans have adapted to malaria over time.…

    This experiment was conducted to study the relative fitness of two phenotypes of the Drosophila melanogaster and how fitness can affect evolution in the population. The phenotypes were placed in two different environments, one in which contained a predator and another with no predator. Results of the experiment would show how the fitness of each phenotype is affected by providing a mechanism, and if evolution was occurring in the population. Two hypotheses were inferred, one for each environment. For the cage uninfluenced by a predator, we hypothesized that evolution would occur due to sexual selection, and that sexual selection would be in favor of the wild-type drosophila. For the cage containing the predator, we hypothesized that the vestigial flies would have a higher relative fitness due to natural selection. A ratio of wild-type to vestigial flies was determined, and was set up in each environment. 10 wild-type to 40 vestigial flies was chosen, giving a total of 50 flies for each environment. Each week the flies were fed, and every two weeks they were counted to represent a new generation. At the end of the 13 week experiment, the last generation of flies were counted and recorded in a data table. The results of the experiment show that evolution was occurring in both cages, and that wild type flies were dominant regardless of the environment.…

    It has often been said that living things, including humans, cannot be well-understood without looking at the evolutionary forces that have shaped them. Biological science and medicine are becoming increasingly more evolutionary as our exponentially-growing knowledge base at all levels – from DNA to the process of biological inheritance; from the biology and genetics of populations and species to the evolutionary processes that shape them; from cells to multicellular beings, and from individuals to the planetary biosphere – reveals more and more clearly how living systems work.…

    Bedbugs have been evolving in the United States since the 1940s and 50s. (1) Due to genetic mutations after World War II a widespread of pesticides known to be DDT was used. The genetic variation makes them resistant to the pesticides. (2) These DDT pesticides were used on the bedbug population, making them resistant to the pesticide. This illustrates natural selection because those resistant with the pesticide survive best. Which is heritable to their population with the resistant pesticide offspring. This give their offspring the best fitness for adaptation to survive and breed resistant pesticide to their offspring as well. (1)…

    In the 1850s, two scientists by the name of Charles Darwin and Alfred Russell Wallace composed the theory of evolution by natural selection. (1) Darwin characterized several claims needed for natural selection to happen, including heritable variation within the population, and the presence of more individuals than the environment can support. They also discovered that certain environments favored certain traits. These circumstances resulted in the preferred traits being the most adaptable and able to reproduce, therefore passing the traits down to the next generation. To get a closer look at natural selection, we set up simulations to look at the reproductive success of an individual relatives to others, or biological fitness. The hypothesis we concluded for the simulations is that the predators on the light towel bench, which represents one of our three environments, would be more fit than the predator in the other two environments.…

    The book, Silent Spring, by Rachel Carson is regarded as the most significant environmental novel as it was the start of the environmental movement. This book highlights the human poisoning of the biosphere through chemicals aimed at pests and disease control, particularly dichlorodiphenyltrichloroethane (DDT). DDT pesticides were particularly harmful because as they entered the biosphere, they not only killed the bugs but also entered the food chain. DDT accumulated in the fatty tissues of animals and humans which had potential to cause cancer and genetic damage. This also contaminated world food supply as DDT can enter any animal that we eat. Despite the immense effect of DDT some insects survived and passed on their resistance resulting in tougher descendants, so more toxic insecticides needed to be…

    Evolution, the changing of organisms to better fit their environment, is the driving force in life’s diversity. Though not widely accepted, due to religious beliefs of the origin of life on Earth, evolution is known to many scientists as the most important way to understand biology. According to Theodosius Dobzhansky, “Nothing in biology makes sense except in the light of evolution.” Though this may not technically be true, this broad statement almost underwhelms the importance of evolutionary changes in every organism on the planet.…

    Since the natural resources are usually limited, the reproduction results to competition for survival by utilizing the scarcely available resources. Species of organisms that posses traits that give them advantage over the others, they usually survive and pass the traits to the next generation unless the others organisms lacking the traits which do not survive the competition. Thus the process of natural selection is determined by the organism’s evolutionary fitness which shows the ability of an organism to survive and reproduce and determines the amount of genetic traits to be passed to the next…

    Perhaps somewhat remorselessly, Dawkins explores the fallibility of life when how genetically superior an organism is determines its success in surviving. His words, “we are built as gene machines”, reinforced to me the impressiveness of our biological makeup and inspired me to not only understand it, but also to explore concepts such as this further.…
