Q: Sudden changes in geologic and climatic conditions can spur what process?


Read this paragraph and choose the correct option from the provided answers:

When geologic and climatic conditions are changing, evolution may occur more quickly. Thus, long periods of little change may be interrupted by bursts of rapid change. This model of the timing of evolution is called punctuated equilibrium . It is better supported by the fossil record than is gradualism. This model suggests that niches left open by sudden geologic and climatic changes may be rapidly filled by bursts of evolution.

 Choices:

- generation

- cloning

- symbiosis

- evolution


A:
evolution
