Question

12.4 compare and contrast convergent evolution and evolution by common descent, and give an example of each. convergent evolution results in similar structures in distantly related species due to similar environmental pressures directing natural selection. which of these characteristics of sharks (fishes) and dolphins (mammals) are due to convergent evolution? drag the convergent evolution characteristics onto the image of both species. use gills to breathe made up of eukaryotic cells predator belong to the class mammalia image of shark and dolphin with dorsal fins and flippers label

Explanation:

To determine convergent evolution traits between sharks (fish) and dolphins (mammals):

• "use gills to breathe": Dolphins are mammals (lungs), so not convergent.
• "made up of eukaryotic cells": All complex organisms (sharks, dolphins) are eukaryotic—this is a shared ancestral trait (not convergent).
• "predator": Both sharks and dolphins are predators, evolving this trait due to similar environmental pressures (hunting in aquatic ecosystems) → convergent evolution.
• "belong to the class Mammalia": Sharks are fish (not Mammalia) → incorrect.

Answer:

predator
