Practice questions

1 of 37Practice questions for this set
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?
