dogs have a reduced nonfunctional digit on their paws known as a dewclaw. what is this an example of?\n○ analogous structure\n○ homologous structure\n○ vestigial structure\n○ mutated structure

Answer

Brief Explanations:

A vestigial structure is a remnant of a structure that was functional in an ancestor but has lost its function over time. The dew - claw in dogs is non - functional and reduced, which fits the definition of a vestigial structure. Analogous structures have similar functions but different evolutionary origins. Homologous structures have a common evolutionary origin but may have different functions. Mutated structures result from genetic mutations and are not specifically defined by being non - functional remnants.

Answer:

vestigial structure
