Actually, echinoderms are more closely related to humans than molluscs.
reptiles
Echinodermata i.e echinoderms - starfish, sea urchins, sea cucumbers
Echinoderms, such as sea stars and sea urchins, are considered closely related to chordates due to their shared evolutionary ancestry within the deuterostome clade. Both groups exhibit similarities in their embryonic development, specifically the formation of the blastopore, which becomes the anus in deuterostomes. Additionally, they share structural features at certain life stages, such as the presence of a notochord in chordate ancestors and certain molecular and genetic similarities. These factors highlight their common lineage and evolutionary relationship.
Echinoderms are considered closely related to chordates due to their shared developmental features, such as the presence of a deuterostome developmental pattern, where the anus forms before the mouth during embryonic development. Additionally, both groups exhibit similarities in their genetic and molecular structures, particularly in their Hox gene arrangements. These characteristics suggest a common evolutionary ancestor, highlighting the evolutionary connection between echinoderms and chordates.
Echinoderms, such as starfish and sea urchins, are considered closely related to chordates, including corals, due to their shared evolutionary lineage within the deuterostomes, a major group of animals characterized by specific developmental features. Both echinoderms and chordates exhibit bilateral symmetry at some stage of their development and share common genetic and embryological characteristics. Moreover, molecular studies have shown significant genetic similarities between these groups, supporting their close evolutionary relationship.
Brittle stars or ophiuroids. These are echinoderms in the class Ophiuroidea closely related to starfish.
They are more closely related to foxes. Both foxes are snakes are vertebrates. Starfish are echinoderms.
the answer is echinoderms are closer related to humans because they have a spine while mollusks do not
