in general, will natural selection result in an increase or decrease in variation? Why does this happen and how, in theory, will it affect evolution in the future
Using evidence from the text, how did natural selection determine the survival of medeival humans during the black death( bubonic plague)? Please explain in 4 to 4 sentences
Use the words: variation, natural selection, favorable traits
natural selection, why is maintaining genetic variation in populations such an important part of species being able to live through environmental changes? Include an example

- How Can We Measure Allele Frequencies in Populations? Explain the connection between changes in population allele frequencies and evolution, and relate this to the observations made by Wallace and Darwin concerning natural selection.arrow_forwardDo you think the human race is continuing to evolve in a Darwinian, genetic sense? Are the genes of our species changing? Do not just write "yes" or "no," but explain why you think so. In addition, include in your explanation of how the mechanisms of evolution, such as natural selection, would be at play.arrow_forwardNatural selection is dependent on several factors, including the ability a population to survive and reproduce within a particular environment. How are both of these factors modeled?arrow_forward
- Is evolution by natural selection based on the desires of individuals within the evolving population? In other words, are individuals able to control natural selection to obtain a certain outcome? Explain.arrow_forwardWhat is neutral evolution? A. Neutral evolution does not exist. B. When certain genes are present or absent in populations due to natural selection (they are advantageous or disadvantageous). C. When certain genes are present or absent in populations regardless of selection (they are not advantageous or disadvantageous). D. When certain genes are present or absent in populations due to sexual selection (they are selected for by the opposite sex).arrow_forwardHow can Darwin's finches explain natural selection and descent with modification? What is another example of natural selection and descent with modification? In both of your answers, you should describe the trait that was selected for/against and why this trait was an advantage/disadvantage. Plus, state how natural selection changed the population over time.arrow_forward
- In order for evolution to occur via natural selection on a particular trait, which of the following must be present for that trait? Which out of the 4 answers below is correct? Only 1 answer is correct Variation, mutations, fitness consequences Variation, fitness consequences, mode of inheritance Genetic recombination, variation, mutations Mutations, fitness consequences, mode of inheritancearrow_forwardA farmer uses DDT to kill insects in his field. The first year nearly all of the insects were killed. By the fourth year, however, nearly all of the insects survived the DDT treatment. Explain the process of natural selection in this population of insects. Include these words - mutation, phenotype, variation, resistance, adaptation, and differential survival.arrow_forwardGenetic variation is the product of completely random events, but acting upon this randomness is a very nonrandom process called natural selection. Explain or give an example.arrow_forward
- What kind of variable traits other than fur or lack of within a population might natural selection act uponarrow_forwardRegardless 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 stasisarrow_forwardIs it true that natural selection allows only the better alleles to be passed onto the next generation? Please explain in details. The explaination should either agree or disagree, not be in the middle.arrow_forward
