Punctualism/Graduated Equilibrium

Front

What is gradualism in evolution?

Back

Gradualism is the model of evolution that suggests species evolve slowly and steadily over long periods of time.

Front

What is punctuated equilibrium?

Back

Punctuated equilibrium is the model of evolution that proposes that species experience rapid changes during short periods of time, followed by long periods of stability.

Front

What does the fossil record indicate about transitional forms?

Back

The fossil record shows transitional forms that can help identify the evolutionary history of a species.

Front

What is an example of human impact on evolution?

Back

Examples include construction, insecticides, and farming, which can alter habitats and affect species.

Front

How do gradualism and punctuated equilibrium differ?

Back

Gradualism involves slow, continuous change, while punctuated equilibrium involves rapid changes followed by long periods of little change.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a variety of forms to adapt to different environments.

Front

What is convergent evolution?

Back

Convergent evolution occurs when unrelated species develop similar traits due to similar environmental pressures.

Front

What role do environmental pressures play in evolution?

Back

Environmental pressures can drive natural selection, leading to adaptations in species over time.

Front

What is the significance of transitional fossils?

Back

Transitional fossils provide evidence for the gradual changes that occur in species over time.

Front

What is the main idea behind the theory of evolution?

Back

The theory of evolution explains how species change over time through processes like natural selection and genetic drift.
