What Is Microevolution?

Improved Essays
Microevolution allows us to see a small scale of evolution over a short period of time. To visually see and test evolution we need organisms that adapt quickly and have short life spans. Fruit flies, Drosophila melanogaster, are model organisms in order to gather as much information within a short period of time. Fruit flies have a life span of about 2 weeks, and are low maintenance, making it easy to see several generations. (Varga, S. J., Qi, C., Podolsky, E., & Lee, D , 2014) According to Hardy Weinberg’s conditions, considering they are met, “no evolution will take place.” (University of South Florida Department of Biology, 2017)
Our fly population is scaled-down, which goes against one of Hardy Weinberg’s conditions. He believed that a

    Determining the affects of natural selection on gall fly (Eurosta) larvae from different predators Ariel O’Neil Biology 1020H Abstract This lab was done with the objective of determining if directional selection causes early larvae death in the gall fly. By first examining the parasitoid wasp and birds predatory actions we can hypothesize and predict the smaller galls will be most likely to survive directional selection.…

    We hypothesized that curly wing flies would have difficulty courting past the flapping of its wings to create a “love song”. The FraxE flies are model organisms of a mutation that causes mental retardation and various behavioral problems. We did not expect very much courtship at all in this group. Lilli flies were similar to the FraxE model except they had the protein that was lost with the mutation placed roughly 50% back into them. We thought the flies with this mutation would have more courtship then the FraxE but less than the curly wing fly.…

    The first video starts off by showing the change of the New Mexico’s Valley of Fire’s land. It had changed because of volcano eruptions that occurred about 1,000 years ago. It made a river of lava over 40 miles long through the dessert. When the lava cooled off, it left the ground black leaving animals that needed camouflage in trouble. The rock pocket mouse uses the dessert sands for protection because it blends in with it.…

    In chapter 3, Wilson compares Darwin’s Theory of Natural Selection to a “recipe with three ingredients” – variation, consequences and heredity – where the end result is definite and unavoidable. Variation may be manifested in the physical appearance, behavior and other measurable or observable characteristics. These distinct differences in traits among individuals determine their survival, reproduction or reaction to situations. Traits are also passed on from parent to offspring because of heredity.…

    For this lab we conducted a population genetics study on the frequency of wild and apterous flies within a small population of fruit flies. The fruit fly Drosophila works well for genetic and evolutionary geared studies because they have a relatively short generation time but are intricate enough to reveal some biological principles that are parallel to many different kinds of eukaryotic organisms. When exposed to artificial selection in laboratory experiments, fruit flies have experienced dramatic changes behavioral and evolutionary traits within ten generations or less (Goldsmith, 1991). It is important to note that wild flies have wings and apterous flies do not. The purpose of artificial selection is for humans to modify species over generations by intentionally breeding two organisms with the objective of acquiring a specific trait.…

    2.Briefly explain why it is important to learn the hardy-weinberg equation and what the equation allows us to study in terms of population genetics -It is important to learn it because it provides us with mathematical evidence that evolution will not occur under certain circumstances such as migration or mutation. Comparing populations to Hardy-Weinberg equilibrium helps us better understand the mechanisms of evolution. With this equation, we can determine if a population is evolving. Under the assumption that the population is not evolving, we can also calculate genotype frequencies from allele frequencies. 3.Explain why race is not a biological concept and why it is in fact not real why is it a folk taxonomy (make sure you define the term as well) can understanding this help current social issues explain -Race is not a biological concept because about as humans, we share about 99.9% of our DNA and have the same set of genes.…

    There are four parts to natural selection and they are genetic variation, overproduction of offspring, struggle for existence, differential survival and reproduction. My Biology class did another lab called “Origami Bird Lab.”. In this lab we started with three birds made out of paper and straws they all had the same width, circumference, and length. We flew the three birds and whichever bird flew farther bred the next generation of birds. The first offspring of every generation had no mutations while the other two birds in each generation had mutations that were determined by a coin and die.…

    As can be expected, both natural selection and mutation are explained in this section of the Framework. The importance of knowing evolution, simply put, is that it “explains the diversity and unity of life” (AP Biology Curriculum Framework, n.d., p. 4). By knowing evolution, one can understand why and how all life has become what it is today. To comprehend the “driving force” behind evolution, one must be familiar with natural selection, which allows individuals with conducive traits to pass their traits onto the next generation. Finally, to cognize how different traits form, one must know of mutations and how they “can be positive, negative, or neutral” (AP Biology Curriculum Framework, n.d., p.51), thus allowing natural selection to eliminate deleterious phenotypes caused by negative changes to the genotype.…

    Writing Assignment #1 Lasiognathus dinema There are a couple misconceptions you might have about evolution and natural selection. The strongest and most important organisms do not survive over the generations. Although evolution occurs due to fitness in an individual or individuals of a species, an organism cannot survive over generations. Fitness is achieved through variations in populations of species through genetic differentiation (Scottville “n.d.”). Since the life cycle of all living organisms is to be born, survive, mate, and die, it is impossible for an organism to live through several generations.…

    The mechanisms of evolution are mutation, gene flow, genetic drift and natural selection. These mechanisms are based upon the changes that occur within an organism’s gene pool and how they affect those organisms and their survivability. Some of these mechanisms of evolution move quickly and affect large populations while others are slow moving and affect small populations. Not all of the evolutionary mechanisms are positive and benefit the population’s long term survival. Commonly these negative effects wipe out smaller populations that tend to be more isolated that large populations which have more genes to stave off the effects.…
