- Q1Which of the following ideas was NOT part of Darwin's contribution to science?descent with modificationnatural selectionsurvival of the fittestinheritance of acquired characteristics30s
- Q2Darwin first began to formulate his concept of evolution by natural selection afterexperimenting with animalsobserving patterns among the geographical location of certain speciesagreeing with Lamarck about the driving force behind evolutionreading the writings of Wallace30s
- Q3Charles Darwin called the ability of an organism to survive and reproduce in its specific environmentadaptationevolutionfitnessdiversity30s
- Q4According to Darwin's theory of natural selection, individuals who survive are the ones best adapted for their environment. Their survival is due to thepossession of inherited adaptations that maximize fitness.possession of adaptations developed through use.lack of competition within the species.choices made by plant and animal breeders.30s
- Q5Anatomical structures that have similar bone structure but do not have similar functions are called:vestigial structuresintermediate fossil formsanalogous structureshomologous structures30s
- Q6Natural selection acts directly onallelesphenotypesgenesmutaitons30s
- Q7If a mutation introduces a new skin color in a lizard population, which factor might determine whether the frequency of the new allele will increase?how many other alleles are presenthow many phenotypes the population haswhether the mutation was caused by nature or by human interventionwhether the mutation makes some lizards more fit for their environment than other lizards30s
- Q8Species Y and Z have very similar proteins, genes and genetic sequences. What is most likely true about these two species? Species YSpecies Y is older than Species Z.Species Y shares a relatively recent common ancestor with Species Z.Species Y evolved for a long time separately from Species Z.Species Y is younger than Species Z.30s
- Q9Anatomical structures that have similar functions but do not have similar structures are called:homologous structuresanalogous structuresvestigial structurescommon structures30s
- Q10The process by which one species significantly influences the evolution of another species is called:co-evolutionadaptive radiationdivergent evolutionconvergent evolution30s
- Q11Change in a population over a period of time is known asevolutionextinctionperiodic catastrophebiogenesis30s
- Q12Whenever two populations try to occupy the same niche(habitat)the gene pool shrinksnatural selection does not take placethey work togethercompetition increases30s
- Q13Which is NOT part of the theory of natural selection?genetic variation among a species is required to get the fittest individualscompetition is part of the natural selection processpopulations grow exponentiallythe natural environment affects what individuals survive30s
- Q14Evolution that produces similar characteristics in unrelated species isco-evolutionconvergentadaptivedivergent30s
- Q15During Darwin's visit to the Galapagos Islands, what did he observe about finches?All of the finches looked completely different.The species resulted from coevolution.Each different group of finches had its own niche (habitat)There were no differences between groups of finches.30s
