The reason for the close relationship between echinoderms and chordates. Concept introduction: The basis of the phylogenetic tree is the evolutionary relationship represented between different lineages to determine the relationship among species. Similarities could arise either due to the ancestral basis or due to the derived character. The differences among animal groups help in determining their distinct characteristics which are not found in other animal groups. The similarities exhibited by different animal phylum represent their close relationship.
