Vestigial structures are: structures that were helpful to our ancestors but do not serve any useful purpose under current conditions structures that are only helpful when there is competition for survival structures that are harmful relics of our evolution structures that appear to contradict our understanding of how evolution works O000
A reasonable definition for a species is: O A distinct kind of animal. O A group of living things with functionally similar traits, for example, all creatures that can fly. O A group of living things with taxonomically similar traits. O A group of taxonomically similar living things in which all healthy members can interbreed and produce fertile offspring. QUESTION 8 If microevolution is any change in the gene pool of a breeding population, then macroevolution is: O A change in the genetic makeup of group that eventually results in the development of a new species. O The mass exctinction of old species to make way for new. O Changes in the physical environment at large. O When microevolution happens on a large scale. * QUESTION 9 What is the primary cause of speciation? O Extinction. O Overpopulation. O Environmental change. O When a breeding population becomes reproductively isolated from its ancestral population, for a long enough time, in a different enough environment, that it…
If vestigial traits are no longer useful to an organism, why don't they evolve out of the population? * Individuals with the trait have developed new ways to use them. Individuals that have the trait continue to survive and reproduce, and they pass on th genes for that trait to the next generation. Individuals that have the trait must have some sort of evolutionary advantage. The individuals that have the trait become less common over time.

« > A Moving to another question will save this response. Charles Darwin was the first person to propose: That the earth is older than a few thousand years. O A mechanism for how evolution occurs. A mechanism for evolution that was supported by evidence A way to use artificial selection as means for domesticating animals and plants.
Fred and George are arguing over evolution. Fred posits that evolution can occur in any population as long as all members gradually undergo change. George disagrees; he thinks that individual memebers of the population do not change but instead have offspring with the trait(s) of interest and thus a population evolves over generations. Who is right? Choose the best answe a. Fred is right! As members of the population respond to the environment, they change to suit it better O b. Fred is right! All memebers of the population must change aroudn the same time O c. George is right Evolution occurs over generations as only the beneficial traits are passed onto the next generation. O d. George is right! Individuals don't change their alleles, but the offspring they have contributes to the change in population allele frequencies
Why is genetic variation important to the process of evolution? (Choose all that apply) If all of the individuals in a population were the same the entire population would be vulnerable to extinction rather than evolut Evolutionary adaptations are the result of a gradual build up of genetic differences over long periods of time Evolution at the population level refers to changes in the gene frequencies in the population over time Individuals must be able to mutate genes in order to adapt to the current situation in their environments
Deer mice are usually found in the woods and are dark brown in color. The deer mice that live in the Sand Hills of Nebraska, however, have evolved a lighter coloring, the result of a change in one gene. The initial population of deer mice in the Sand Hills was probably dark brown, like all other deer mice. What was the driving force behind the evolution of this population? * Mutation Speciation Equilibrium Predation Schc Support | Schoology Blog | PRIVACY POLICY | Terms of Use US
Which of the following groups of organisms have evolved as a result of artificial selection? * Farm crops like wheat, corn, and lettuce O Predators like lions, cougars, and bears Large trees like redwoods and sequoias Gastropods like slugs and snails IMO
Which of the following statements is true regarding the phrase "adaptive radiation"? O It refers to multiple speciation events within an evolutionary lineage. It refers to many populations of the same species. It is the result of genetic drift occuring many times over evolutionary time. Gene flow is an evolutionary mechanism that can account for adaptive radiations.
Which of the following statements regarding evolution is FALSE? evolution is a relatively slow process Oall of these statements are TRUE evolution operates at a variable speed transitional forms appear during periods of rapid evolutionary change evolution operates over the course of multiple generations
