What common evolutionary theme explains the successful diversity within *Mustelidae*?

Answer

Adaptation through modification of a functional template

The vast success and diversification of the *Mustelidae* family, spanning marine predators to terrestrial burrowers, is fundamentally built upon a strategy of adapting an existing, highly effective structural blueprint. The ancestral form provided key traits such as agility, scent-based tracking capability, and a relatively small size. Subsequent evolution did not reinvent this structure but rather tweaked these existing traits—such as modifying the torso for burrowing or enhancing fur density for cold—to suit specialized survival needs. This process of refining a functional template allowed for varied specialization without losing the core efficiency inherited from the ancient weasel-like carnivorans.
