BIS 2B Study Questions For Natural Selection 1. Georges Cuvier was one of the many scientists who studied fossils. He observed fossilized marine forms in places that were now mountain tops, found fossils of organisms that no longer existed, and noticed that fossil forms appeared to change from older to younger strata. Which explanation for these observations did he prefer? a) all geological processes that operate now, operated then b) high reproductive rates resulted in limited survival of each type c) a series of great catastrophes occurred in each environment d) organisms evolved in some places and became extinct in others e) continents had moved, altering the distributions of many species 2. Which of the observations below would support the idea that controlling which individuals were permitted to mate could have a large effect on the phenotypes of offspring? a) the naturally-occurring variation within a population b) the results of plant and animal breeding trials c) the similarity between birds on two islands d) the fossil record for shelled animals e) the similarity between parents and offspring 3.
