question 15 of 20
which sequence places tiktaalik in the correct evolutionary order?
○ ray-finned fish, tetrapods, tiktaalik
○ tetrapods, lobe-finned fish, tiktaalik
○ lobe-finned fish, tetrapods, tiktaalik
○ lobe-finned fish, tiktaalik, tetrapods
○ tetrapods, ray-finned fish, tiktaalik

Explanation:

Tiktaalik is a transitional fossil between lobe-finned fish (its ancestors) and tetrapods (four-limbed vertebrates it preceded). So the correct order is lobe-finned fish first, then Tiktaalik, then tetrapods.

Answer:

lobe-finned fish, Tiktaalik, tetrapods
