Question

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

Answer 1

Answer:

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

Answer 2

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:

Hemichordates and chordates are two deuterostomes phyla.

Alongside the phylum Echinodermata, Hemichordates and chordates 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 larva phase of Hemichordates. Differences occurs as echinoderms are in adult stage.
