Dipleurula concept of origin of chordates biology discussion
Answers
Dipleurla is a hypothetical larva which is present in the Echinoderms. Dipleurula hypothetically represents an anncestral form for these primitive deuterostomes which is present in the earth. Echinodermata are basically derived from the hypothetical dipleurula which is present in earth. It represents the type of basics of all larva formed from the Eleutherozoa which actually is the main of sea stars, sea hedgehog, sea rollers etc.
Dipleurula is the hypothetical larva of Echinoderms. Actually, it signifies the kind of basis of various larva forms of Eleutherozoa, to that the sea-hedgehog, sea-rollers, sea-stars, and sand stars.
The In other words, Dipleurula is the bilaterally symmetrical and ciliated echinoderm larva.
They are actually derived from hypothetical dipleurula. The larvae of invertebrate chordates are minor larvae whose bond to basic dipleurula-type larvae of the echinoderms as well as hemichordates is somewhat vague.
