Question

name the four hall Marks of chord ater and explain the principle function of Seen of them?​

Answer 1

Answer:

The four distinctive characteristics that, taken together, set chordates apart from all other phyla are notochord, dorsal tubular nerve cord, pharyngeal pouches, and postanal tail.

In chordates, four common features appear at some point during development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail

Pharyngeal slits are a third chordate feature; these are openings between the pharynx, or throat, and the outside. They have been modified extensively in the course of evolution. In primitive chordates, these slits are used to filter food particles from the water.
