What does echinoderms and deuterostomes indicate about their relationship with other animals?
Echinoderms and deuterostomes share a fundamental evolutionary relationship, as echinoderms are a subgroup within the deuterostome clade. This indicates that both groups, along with chordates and hemichordates, share a common ancestor, highlighting their evolutionary link. Deuterostomes are characterized by their embryonic development, where the anus forms before the mouth, a feature that distinguishes them from protostomes. This shared developmental pattern suggests that echinoderms and deuterostomes have diverged from a common lineage, influencing their anatomical and physiological traits.
