it means slits it means slits
It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.

peristalsis is voluntary, the pharyngeal-esophageal is the invoulantary movements of swallowing!

There are several characteristics that all chordatas share, including a dorsal hollow nerve cord. They also all will have pharyngeal slits and a notochord.
Yes, lancelets do have pharyngeal pouches. These pouches are openings in the pharynx that are important for filter feeding and gas exchange in these small marine animals.
Yes, frogs have pharyngeal pouches, which are structures in their throat that aid in respiration. These pouches play a role in the exchange of gases during breathing.
no they dont no tigers do that
Fish
gills
gill slits
Yes, chordates typically have pharyngeal pouches at some stage in their development. These structures are important for the embryonic development of various structures, such as gills in aquatic species or parts of the head and neck in terrestrial species.
a hollow nerve cord, a notochord, pharyngeal pouches, and a postanal tail
An example of an animal that has a notochord, nerve cord, and pharyngeal pouches at some point during its development is a chordate, such as a human. In embryonic development, humans possess these structures, which are characteristics of chordates.
It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.
for plato users the answer is B. notochrd, nerve cord, pharyngeal gill slits, postanal tail
All Chordates have:1) a notochord2) pharyngeal slits3) a postanal tail4) a hollow dorsal nerve chordRead more: What_are_the_four_characteristics_of_a_chordate
