1. Which of the following species characteristics would not put them at risk of extinction? A. globally-distributed over most available habitats (like the Norway rat) B. limited dispersal abilities (like many European trees during the last ice-age) C. relatively low genetic diversity (like the cheetah in Northern Africa) D. relatively small population sizes (like the North American whooping crane) E. relatively large body mass (like most of the Cretaceous dinosaurs) 2. The greatest extinction in the fossil record, causing the extinction of about 52% of marine vertebrate families from that time period (as well as high numbers of terrestrial extinctions), is considered to be: A. the Ordovician/Silurian extinction B. the Devonian/Carboniferous extinction C. the Permian/Triassic extinction D. the Triassic/Jurassic extinction E. the Cretaceous/Tertiary extinction 3. The timing of the above extinction event is defined by which of the following boundaries? A. the beginning of the Paleozoic Era B. the end of the Mesozoic Era C. the beginning of the Cenozoic Era D. the end of the Cenozoic Era E. the beginning of the Mesozoic Era
