Which of the following is not a trait on which natural selection can act? a size of ears b fur/hair color c broken bones d thickness of fur
Biologists sometimes say that “natural selection depends on the specific environment where a species lives.” What does this statement mean? A) A) If populations of a species are in different environments, traits that individuals need to meet their needs in each environment will appear. B) Traits can be helpful or harmful. If populations of a species are in different environments, some traits that are helpful in one environment might be harmful in another environment. C) Traits are always either helpful or harmful, and the environment of a population doesn’t matter. If populations of a species are in different environments, the same traits will always be helpful. D) Species were formed to perfectly match their environment. The traits of individuals in a species depend on the specific environment in which they were created.
A farmer breeds sheep with the desired traits of disease resistance and tine wool. After several decades of breeding efforts, the farmer's flock is resistant to disease and produces fine wool. Which evolutionary mechanism is responsible for the changes in the gene pool of the farmer's flock? A:Sexual selection B:Artificial selection C:Natural selection D:Gene flow
Which question below directly corresponds to whether Lamarck or Darwin are correct about their theories of the mechanisms of evolution? A.) Why don’t the shorter neck giraffes feed on grasses and lower vegetation? B.) How would the shorter necked giraffes in Lamarck’s theory survive to reproduce and pass on the “need” for longer necks if they were unable to reach food? C.) Why won’t the taller necked giraffes in Darwin’s theory provide assistance to the shorter giraffes since they are the same species? D.) Will the smaller giraffes be more adapted to hide from predators since they wouldn’t be visible from greater distances?
Does natural selection occur when which of the following conditions are met? A. Variations between individual organisms lead to differential survival chances. B. The conditions in an ecosystem support a wide range of living organisms C. Individual organisms depend on each other to obtain available resources. D. Habitat and nutrient resources in an area are plentiful over a long period of time.
What does “descent with modification” mean?a. Populations that change quickly are likely to become extinct.b. Inherited traits change from generation to generation.c. Tracing an evolutionary tree from top to bottom reveals changes inspecies diversity.d. Parents change their own features before passing them on to offspring.
Which claim about natural selection is not true? A. Directional selection decreases genetic diversity within a population B. Balancing selection (heterozygote advantage) maintains genetic diversity within a population C. Negative Frequency-Dependent selection maintains genetic diversity within a population D. Natural Selection always has a greater evolutionary effect in small populations than it does in large populations
Which of the following is true about natural selection? a) It always results in the evolution of new traits b) It always results in the strongest individuals surviving c) It always results in the fittest individuals reproducing d) It always results in the best-adapted individuals surviving
In your own words, how does Genetic Variation support natural selection? Use at least 1 example from the Beaks of Finches lab in your answer.
Consider Lamarck’s idea in a hypothetical situation. For example, you decided that when you have children, you want them to be big ang strong. You decided to go to the gym every day for a year. You did all your exercise routines diligently and you were able to develop really bulky and toned muscles because you believed that your kids would inherit your big impressive muscles. Do you think this would work? Justify your answer using the concepts you have learned from Genetics, as well as Darwin’s concept of evolution.
According to Darwin’s model of evolution, evolution can only occur if there is some variation present among the individual members of a population. Which statement best describes the source of this variation among members of a species? A) variation exists because different individuals will have different access to food and other resources B) individuals will vary depending on geography and climate C) variation exists because not all genes will be affected D) variation among individuals may arise as a result of mutations in the genetic code
One of the lines of evidence that led Darwin to the theory of natural selection was his study of artificial selection. Plant breeders and pigeon breeders select offspring with specific traits in mind beforehand. a) However, since humans are an integral part of the natural world, do you think that artificial selection might be more appropriately termed “natural selection”? Why?
