    What is natural selection According to en.wikipedia.org/wiki/Natural_selection Wikipedia, “ Natural selection is the gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution.” In simple terms natural selection is the creation of slightly differing species within a population…

    "Knowledge within a discipline develops according to the principles of natural selection." How useful is this metaphor? Many times questioning existing knowledge leads to new evidence that either supports the knowledge or proves to be wrong. Thus knowledge that is preserved is based on natural selection. However how does natural selection determine the value of knowledge? In History, natural selection determines the value of knowledge through the use of memory and belief. Whereas in natural…

    yellow beetle coloration succeeded, the initial state and increase in frequency of allele in yellow beetles to 100% made the decrease in genetic variation. This was seen in the outcomes of the exercise, unfavorable traits were removed through natural selection and such individuals with much fitness, in this case, the yellow beetles, succeeded because of the profusion of the resources (only 120 beetles may stay alive at any point) and yellow has a selective advantage in such environment like…

    define Natural Selection. In order for natural selection to work, it has to occur along with a bunch of other things. The process in which natural selection works is where organisms with favorable traits are more likely to reproduce. By doing this they pass on these traits to the next generation! Over time this process allows organisms to adapt to their environment, thus, making the favorable traits increase in population. Genetic variation is vital, without it natural selection wouldn’t be…

    Process and analyse information from secondary sources to explain a modern example of ‘natural’ selection. (Structural, Physiological, Behaviour) Some organisms, such as bacteria and insects, produce large numbers of offspring. Amongst large numbers of bacteria offspring, some individuals may carry genes that give them resistance to antibiotics. These individuals are then able to survive and reproduce with reduced competition from other members of the same species. Each generation will produce a…

    Natural selection is the process by which individuals with characteristics that are advantageous to reproduction in a particular environment leave more offspring in the next generation, thereby increasing the proportion of their genes in the population gene pool over time. An example of modern natural selection that is frequently observed is the insecticide resistance in pest insects. Prior to the use of pesticides in the 1940s, crop insect populations only contained a limited amount of genetic…

    contention came about. Some believe sex selection is an appropriate choice. On the other hand, others think couples shouldn’t have the option because it’s experimental and messes with the course of natural selection. Either way, gender determination is becoming a world wide known option for essentially everyone. We will take a look at reasons why it’s a suitable path to take as well as reasons for it being unethical and why. People tend to resort to gender selection for more than just an…

    Natural selection is the main scientific method of evolution and the precursor to an organisms transformation over a scale of time. In natural selection organisms that survive have heritable traits that aid in reproduction thus becoming prevalent in that organisms population. Jurmain(2013) explains in our textbook, that, through the aid of Thomas Malthus ideas, Charles Darwin was able to grasp the explanation of selection in nature (page40). Jurmain(2013) states “In the struggle for existence,…
