Indicate the appropriate mechanism(s) of evolution at work in the following: Remember that forces may oppose one another! Choose from: Non-random or Assortative mating Sexual selection Gene flow (Migration) Kin selection Genetic drift (Founder effect, Bottleneck, Mutation Natural (but non-sexual) selection. etc.) Prior to 1970 a population of moths with dark brown coloration blended in well with the trees they live on. Bird predation on the moths is very low in the population. In 1976 a deletion in the genetic code of an individual male moth occurred, resulting in a new color morph (White). The white moth was favored for mating by the wild females, and by 1980 14% of moths in the population exhibited the white color. Jays (birds that feed on moths) in the area could readily see these white moths and, once they had learned to look for them, eliminate the white moths from the population by 1981.

Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal.) Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce about 500 offspring are born but only 100 of them live long enough to reproduce themselves. Explain how natural selection will occur and include the 4 principals of natural selection.
When discussing natural selection and behaviour, we often say that members of a species have certain behavioural traits because those traits are adaptive, in the sense that they increase inclusive fitness relative to alternative forms of those traits that have existed in the past. Instead of emphasizing the adaptiveness of behavioural traits, some biologists describe natural selection as a process that operates on nervous system traits, increasing the prevalence within a population of particular patterns of neural circuitry and neurobiological mechanisms. As an alternative to emphasizing either the behaviour or the nervous system, some biologists describe natural selection as a process that operates on genes; according to this perspective, certain forms of certain genes (ie., particular alleles) increase in prevalence within a population relative to alternative forms of those genes. Which, if any, of these three perspectives on natural selection and behaviour do you think is the most…
The domestication or breeding of animals to have as pets, livestock on farms, or for work purposes is a form of artificial selection. Charles Darwin used these practices to support his theory of species change by natural selection. How is artificial selection similar to natural selection? When animals with favorable traits are bred with animals with unfavorable traits, the offspring will have favorable traits, so breeders were changing species by removing certain traits. For artificial selection to work, only the strong survive to reproduce. By breeding animals with specific traits, breeders were able to produce a wide variety of breeds within a short period of time. Artificial selection involves breeding two different species and determining if a hybrid organism can be produced.
Natural selection acts upon ____________________________, evolution upon _______________________________. What is the gene pool and how does natural selection act upon it? If a version of a gene confers an advantage to survival and reproduction, that version of the gene will be favored by natural selection and we can expect the frequency of that gene to ______________________ within the population over time. Versions of the gene that do not confer an advantage (or confer a disadvantage) should become _______________ prevalent . This generation to generation change in the gene pool is called ________________________. Changes to the genetic makeup of a population and the individuals within it can arise via two mechanisms. List and describe both. Both of these processes are ________________________________. Once created, new combinations of genes will be acted upon by _________new alleles_______________________. How is Darwinian “fitness” different than the typical definition used in…
Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population

EVOLUTION LINK Write short paragraphs explaining each of the following statements: (a) Natural selection chooses from among the individuals in a population those most suited to current environmental conditions. It does not guarantee survival under future conditions. (b) Individuals do not evolve, but populations do. (c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive. (d) At the molecular level, evolution can take place by the replacement of one nucleotide by another. (e) Evolution is said to have occurred within a population when measurable genetic changes are detected.
Match the words. There are three phases of evolution expressed in the modern theory of evolution. First, genetic variation is produced at three levels. At the level of DNA,________ is a chemical change in the DNA molecule, which gives rise to variation. At the level of the individual organism, __________ gives rise to variation during the formation of gamete cells. At the level of the population, migration gives rise to variation. Second, there is a reduction of genetic variation by two processes. One process,_________ is the chance (or random) removal of genetic variants due to sampling error from generation to generation. It is especially effective in small populations. The other process, _________, eliminates the less fit variants (such as those less successful at avoiding predators or finding food). meiosis reproductive isolation genetic drift natural selection gene mutation
The Hardy–Weinberg principle states that allele and genotype frequencies remain constant from one generation to the next, as long as specific conditions are met.Choose Yes or No for the conditions that must be met from the provided statements below. Mutations are exponentially occurring. All members of the population breed. Everyone produces the same number of offspring. The population is infinitely large. There is no migration in or out of the population. No net mutations are occurring. Natural selection of beneficial traits is occurring. Natural selection is not occurring. All mating is completely random. Offspring are able to migrate out of the population.
Regardless of the rate of evolutionary change, the product of genetic alterations is ultimately tested by Natural Selection. Gradualism accounts for the constant yet slow linear modification of a population while punctuated equilibrium accounts for long periods of stasis followed by rapid divergence (multiple forms emerging). -First, in no more than two sentences, explain Natural Selection (use your own words).-Second, explain the dynamics of selection. If natural selection acts on individuals, how might itshift allele frequencies in a population?-Third, explain gradualism and punctuated equilibrium in terms of selection. When discussingpunctuated equilibrium, remember that selection is still active in times of stasis
What is the role of variations in a evolution _if heterozygosity is reduced,what happens to the potential for evolution?the phenotype and genotype of a population is due to a mosaic of random and directed process.some of these have to do with history,some are related to adaptation etc.As completely as possible , discuss the role of chance and direction in evolution and in determining the phenotype of a population
What evolutionary mechanism is occuring in each of the following examples, justify your answer: In a population of Darwin’s Finches (Geospiza sp.) there is a large variation in beak size. Grass and mallow seeds can only be eaten by finches with small beaks. Seeds from thorn shrubs can only be eaten by birds with larger, thicker beaks. During a series of years with less rain, grasses and mallows are unable to reproduce and so only thorn shrub seeds are present. Over the course of this drought, the average size of finch beaks becomes larger. Columbine flowers are pollinated by hummingbirds and hawkmoths. Hawkmoths prefer to pollinate yellow flowers, while hummingbirds prefer to pollinate red flowers. Most flowers in a certain population are an intermediate orange color to attract both pollinators. Ensatina from one population are able to survive by camouflaging with their backgrounds. Ensatina from the other population are bright orange mimics of a poisonous newt (Taricha). Hybrid…
