Step 1
Which evolutionary concept is demonstrated in the diagram?
Answer
The evolutionary concept demonstrated in the diagram is Punctuated Equilibrium (Option D). This concept is characterized by relatively rapid changes in phenotypes that occur during brief episodes of speciation, interspersed with long periods of stability, as illustrated by the significant phenotypic changes shown from generation 1 to generation 12.
