The evolution of the modern *Carcharodon* tooth structure is characterized by which final shape?
Answer
Broad, triangular shape
The dental evidence tracked through geological strata illustrates a clear process of gradual modification leading to the modern great white's signature dental tools. Earlier shark teeth in the lineage were sometimes thicker or possessed less precise serrations. Over time, this morphology was honed through selection pressure. The culmination of this refinement process is the optimized structure characteristic of the contemporary *Carcharodon carcharias*: a broad, triangular tooth crown with highly efficient, blade-like cutting edges and distinct serrations. This specialized architecture is perfectly suited for slicing through the flesh of moderately large marine mammals and fish.
