Explanation The embryonic stages of humans do possess the notochord. The embryo is a three-cell layered mass in the humans; they have coelom body cavity and nerve cord. So, the humans are placed in the subphylum of vertebrata. The phylum including the subphylum vertebrata is called chordata. So, the name of the phylum, to which humans belongs is chordata . All chordates have a common feature and that is the presence of notochord...
