Question

4.f - unit b: evolution and speciation assessment
the model of punctuated equilibrium is supported by the evidence of
○ analogous structures in the fossil record
○ the sudden appearance of new species in the fossil record
○ species that are not in the fossil record
○ geographic isolation such as separation due to shifting plates

Explanation:

The punctuated equilibrium model proposes that evolution occurs in rapid bursts (punctuations) of speciation followed by long periods of stasis (equilibrium). The sudden appearance of new species in the fossil record aligns with this model, as it shows rapid speciation events. Analogous structures relate to convergent evolution, not punctuated equilibrium. Species not in the fossil record or geographic isolation don't directly support punctuated equilibrium's key idea of rapid speciation in the fossil record.

Answer:

the sudden appearance of new species in the fossil record
