Question

Fossil records support the idea that periods of little change may be interrupted by bursts of rapid change, an evolutionary model contrasted by what?

Answer 1

gradualism

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.
