C) the evolution of humans from primates
D) the adaptations of flowering plants driven changes in pollinator behavior
E) the evolution of antibiotic- resistant bacteria

Answer 1

Answer: B) the mass extinction of the dinosaurs 66 millions years ago

Macroevolution is a term used to define changes of whole taxonomic groups over long periods of time. The extinction of the dinosaur is not an example of this evolutionary process. The changes occurred over a relatively short period of time and did not involve changes in a taxonomic group, but rather their extinction.
