Why are Echinoderms considered to be closely?
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.
Why are echinoderms considered to be closely related to corroded?
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.
Why are enchinoderms considered to be closely related to chordates?
both have deuterostome development

Why are Echinoderms considered to be closely related to chordate?
both have a nerve cord
Does echinoderms have a close evolutionary relationship with chordates?
Yes they do. Echinoderms, which include starfish, and chordates, which include humans are closely related in an evolutionary sense due to the way their embryos are formed in the early stages of development. Once past that point, the very obvious differences form.
Which phyla are more closely related to each other Sponges cnidarians flatworms roundworms arthropods mollusks annelids echinoderms or chordates?
Sponges (Porifera) are the most basal and diverge early in the evolutionary tree, making them more distantly related to the other phyla. Cnidarians (such as jellyfish and corals) share a closer relationship with the bilaterians, which include flatworms, roundworms, arthropods, mollusks, annelids, echinoderms, and chordates. Among these, arthropods, mollusks, and annelids are more closely related to each other and form a clade known as Lophotrochozoa and Ecdysozoa. Echinoderms and chordates are grouped within the Deuterostomia, indicating a closer evolutionary relationship between them compared to the remaining phyla.
Why are echinoderms more closely related to humans than jellyfish?
Actually, echinoderms are more closely related to humans than molluscs.
Why are enchidorms considered to be closely related to chordates?
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.
What phyla is closest related to chordates?
The phylum most closely related to chordates is probably the phylum Echinodermata, which includes sea stars, sea urchins, and sea cucumbers. Both phyla share a common ancestor and are part of the Deuterostomia clade, characterized by similar developmental patterns. Additionally, molecular and genetic evidence supports the close evolutionary relationship between echinoderms and chordates.
What invertebrates are most closely related to humans?
Echinodermata i.e echinoderms - starfish, sea urchins, sea cucumbers
What do sciences call brittle starfish?
Brittle stars or ophiuroids. These are echinoderms in the class Ophiuroidea closely related to starfish.
