The body shape of a dolphin and a tuna are ____. ​
A)homologous structures
B)comparative structures
C)analogous structures
D)repetitive structures
E)vestigial structures

Quizplus · Accepted Answer

Dolphin and tuna have analogous structures because they have similar body shapes but evolved independently to adapt to their aquatic environment. Homologous structures are structures that have a common evolutionary origin but may have different functions, while vestigial structures are remnants of ancestral features that no longer serve a function. Comparative structures and repetitive structures are not recognized scientific terms in the context of evolutionary biology.
