Question

change in a species that occurs in relatively short time period; point change; punctuated equilibrium; rapid speciation; momentary adaptation

Explanation:

To solve this, we analyze each option:

• "point change" is not a recognized term for species change over time.
• "punctuated equilibrium" is a theory stating that species experience long periods of stasis (little change) interrupted by relatively short periods of rapid evolutionary change, which matches the description of change in a species over a relatively short time period.
• "rapid speciation" focuses on the formation of new species rapidly but doesn't fully capture the concept of short - term change in an existing species' evolution pattern as "punctuated equilibrium" does.
• "momentary adaptation" implies a very short - lived adaptation, not the evolutionary change over a short (but still significant in evolutionary terms) time period as described.

Answer:

B. punctuated equilibrium
