Gradualism is a pattern of evolution in which:
A. A single species evolves into several closely related species.
B. Several distantly related species develop similarities.
C. A species evolves at a slow, steady pace.
D. A species has periods of little evolution interrupted by periods of rapid evolution.
Mass extinction would most likely result from which of the following events?
A. A disease kills off a single species of predator within an ecosystem.
B. A wildfire burns a national park.
C. Global temperatures drop several degrees after several massive volcanic eruptions.
D. A massive earthquake strikes North America.
Answer (2)
1. C. a species evolves at a slow, steady pace.
Gradualism, is the process by which a certain specie or creature undergo changes and variations in a limited and solely focusedly confined in long period of time.
2. A. A disease kills off a single species of predator within an ecosystem.
Mass extinction is a massive and global elimination in a certain specie or species. It doesn’t involve itself only in a secured and measurable area but it impacts the whole large-scale of population as a whole.
Gradualism is the evolutionary process where species evolve slowly over time, while mass extinction typically occurs due to sudden and drastic environmental changes. For the questions posed, the selected answers are C for gradualism and C for mass extinction.
