Embryology Evidence Practice Test

A student claims: “The rabbit is more closely related to the chicken than to the snake.” Use the embryo images at Stage 2 to choose the best-supported claim.

Which claim is best supported by the embryological evidence (embryology provides evidence for relatedness, but it is one line of evidence)?

A student compares embryos at the same stage (Stage 1) for three species: shark, salmon, and human. The images show shark and salmon embryos are very similar in overall shape and have similar gill slit (pharyngeal pouch) appearance, while the human embryo shares some features but is less similar overall. The student claims: “Shark is more closely related to salmon than to human.” Since embryology provides evidence for relatedness, which evidence-aligned statement best supports the claim?
