Question

What evidence links echinoderms, hemichordates and chordates to the same evolutionary lineage?

Answer 1

Answer:

The conserved area in the genome of these two worms provides the first evolutionary link between hemichordates and chordates, and, as a result, all deuterostomes – thus supplying evidence for a common lineage between humans and their less complex relatives.

Explanation:

Hemichordata and Chordata are two deuterostome phyla

Alongside the phylum Echinodermata, Hemichrodata and Chordate have a place with a typical ancestor

Both hemichordates and chordates are coelomates

Hemichordates are worm-like, marine animals while chordates live in water, land, and air  

Echinoderm larva is a two-sided fit as a fiddle which is like the larval phase of hemichordates. Differences occur as echinoderms are in adult stage

Answer 2

The  evolutionary linkage between echinoderms hemichordates and chordates can be found out by the similarity in their characteristics due to the same arisal from the same type of organisms

Explanation:

• Echinoderms hemichordates and chordates all have  organ system level of organisation.

• They deuterostome organism and they have developed alimentary canal.

• In addition to this there is a similarity between the hemichordates and the echinoderms which says that both are almost marine or freshwater in nature. However the chordates can be found in all types of habitats.

• The  hemichordates and the chordates have similarity of having bilateral symmetry whereas the echinoderms have 5 plane radial symmetry
