Are Humans Deuterostomes

Protostomes include the remaining bilaterian species.
Are humans deuterostomes. Composed of the first humans. Share or comment if you agree it is true that some people never develop beyond this stage. So this is the line in the OPs post that you linked to that is misleading.
Protostomes are primitive invertebrates while deuterostomes include echinoderms and chordates. Deuterostomes are divided into Echinodermata Chordates Urochordata Cephalochordata Vertebrata and Hemichordata. A mouth forms at first.
Species of the genus homo are called humans. Deuterostomes belong to the even larger bilateria group. Protostomes show spiral and determinate cleavage during development.
But the thing is that as I have found out there is no archenteron in human embryo at all. The bilaterian tree unites two major clades deuterostomes eg. Deuterostomes further have three significant classifications which are - Chordata Echinochordata and Hemichordata.
However we are a relatively new species. PROTOSTOMES Protostomes include flat worms annelids arthropods molluscs and some minor phyla. Most bilaterian phyla come under protostomes.
Echinoderms are the most closely related phylum to the phylum Chordata which includes many complex organisms such as humans. In understanding these two terms it would be important to pay attention to how the embryonic development of. This division helps in understanding relationships of different groups of animals.
