AP Biology Test Notes- Unit 7  Online Quizzes Darwin's mechanism of natural selection required long time spans in order to modify species.  From whom did Darwin get the concept of Earth's ancient age? Charles Lyell Natural selection is based on all of the following EXCEPT Individuals must adapt to their environment. Which of the following MUST exist in a population before natural selection can act upon that  population? Genetic variation among individuals AND sexual reproduction DDT was once considered a "silver bullet" that would permanently eradicate insect pests.  Today, instead, DDT is largely useless against insects. What would need to be true for pest  eradication efforts to have been successful in the long run? All individual insects should have possessed genomes that made them susceptible to  DDT. Structures as different as human arms, bat wings, and dolphin flippers contain many of the  same bones, these bones having developed from the same embryonic tissues. How do  biologists interpret these similarities? By identifying the bones as being homologous. AND by proposing that humans, bats,  and dolphins share a common ancestor The theory of evolution is most accurately described as An overarching explanation, supported by much evidence, for how populations change  over time. Which of the following pieces of evidence most strongly supports the common origin of all life on  Earth? All organisms use essentially the same genetic code. "Improving the intelligence of an adult through education will result in that adult's descendants  being born with a greater native intelligence." This statement is an example of Lamarckism. Who was the naturalist who synthesized a concept of natural selection independently of  Darwin? Alfred Wallace Given a population that contains genetic variation, what is the correct sequence of the following  events, under the influence of natural selection?      1. Differential reproduction occurs.      2. A new selective pressure arises.

     3. Allele frequencies within the population change.      4. Poorly adapted individuals have decreased survivorship. 2,4,1,3 Which hypothesis of inheritance, common at Darwin's time, caused many to question the ability  of natural selection to bring about adaptation in populations? Blending hypothesis
