Question

question: a specices changes significantly in a few generations and then stabilizes. what type of evolution is this? answer options: select one of four allopatric equilibrium punctuated equilibrium allopatric speciation graduated speciation

Explanation:

Punctuated equilibrium is an evolutionary theory where species experience rapid change in a short time (few generations) followed by long periods of stability. Allopatric equilibrium is not a standard evolutionary term. Allopatric speciation involves geographic isolation leading to new species. Graduated speciation implies gradual change over time, not rapid then stable. So the correct option is Punctuated equilibrium.

Answer:

B. Punctuated equilibrium
