- Fill in the blank: In punctuated equilibrium, the period of time during which a species remains the same is called 000‾\underline{\phantom{000}}000.
- Which of the following words means a state of physical balance?
- What is equilibrium?
- Which model of evolution is based on the fossil record?
- After a long time of stability, an extinction event wiped out the dinosaurs and led to the rapid evolution of many mammalian species. What is this an example of?
