Answer
B. evidence of convergent evolution.
Solution
We need to analyze the options provided regarding the similarities between the fins of sharks and dolphins.
A. Evidence of common ancestors: Sharks and dolphins do not share a recent common ancestor, as they belong to different evolutionary lineages (sharks are fish, and dolphins are mammals).
A. Evidence of common ancestors: Sharks and dolphins do not share a recent common ancestor, as they belong to different evolutionary lineages (sharks are fish, and dolphins are mammals).
B. Evidence of convergent evolution: This is a strong possibility. Sharks and dolphins have evolved similar adaptations (fins) independently due to similar environmental pressures, which is characteristic of convergent evolution.
C. Share homologous structures: Their fins are not homologous; they are analogous structures because they evolved independently.
D. Share vestigial structures: Neither sharks nor dolphins have vestigial fins; their fins are functional adaptations.

Simplify this solution The Deep Dive
The fins of sharks and dolphins are excellent examples of how different species can evolve similar adaptations to thrive in similar environments, despite having different evolutionary histories. This phenomenon, known as convergent evolution, shows that nature can come up with similar solutions to similar problems! In the ocean, both sharks and dolphins face challenges like swimming efficiently and hunting prey, which led to this fascinating similarity in their body structures.
While sharks are fish and dolphins are mammals, their fins serve a similar purpose in locomotion. This similarity isn’t due to shared ancestry, but instead highlights the incredible adaptability of life on Earth. It’s a reminder that living organisms can arrive at similar traits through very different evolutionary paths, showcasing the wonderful diversity of life!
