- Which of Darwin's five 'theories' was something that he strongly emphasized but that we now think is a bit over emphasized on his part. Group of answer choices A. evolution has happened B. evolution is a process of change and splitting C. evolution is a very slow and gradual process D.all life has a common ancestor E.natural selection is the primary force causing evolutionarrow_forwardImagine that some lizards from both islands are brought to a laboratory and lizards from each population are separately bred for a generation. The offspring resemble their parents (i.e. they look like lizards from their home island). Does this support or contradict the idea that evolution has occurred? Group of answer choices a. support because it implies that a genetic change has occurred b. contradict because the lizards were removed from the islands c. support because the phenotype matches the environment d. contradict because the environment is different in the lab e. support because it is a major change in phenotypearrow_forwardWhich of the following best explains the role mutations play in natural selection?A. Most mutations are negative and result in the extinction of the entire speciesB. Mutations may appear for one or two generations, but they usually disappear quickly.C. If the environment changes, an existing organism develops a mutation that will help them to survive.D. Some mutations give individuals an advantage in their environment, allowing them to survive and reproduce.D is my answer is it correct?arrow_forward
