How does the chick embryo resembles human embryo?
As all animals including chicken come form the same domain of life eucariota they have similar characteristics. as in principle the embrio of animals forms the same way and seperates its development at a certin stage acording to the different specie. the main reson for this similarity in development is the genetic similarity of species and as they all use similar cell-cell interactions by theri development.

Are the members of phylum chordata vertebrates?
All vertebrates are members of the phylum Chordata, but not all creatures in Chordata are vertebrates. There are three subphylums in Chordata. Two of them are invertebrates - Urochordata (tunicates) and Cephalachordata (lancelets), while the third is Vertebrata (vertebrates). This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body. In the tunicates, the adult form no longer has the notochord. Another characteristic they share is that, at some stage during their lives, they have pharyngeal grooves and pouches that develop into other essential parts of their anatomy (many textbooks still state that all vertebrate embryos have gill slits, but there has been a great deal of development in the science of embryology to refute this claim). Chordates all have a post-anal tail, which means an extension of the notochord and nerve chord behind the anus, although this feature is no longer present in the mature forms of some creatures such as frogs, and some mammals such as people. Chordates also have a closed circulatory system, although not all Chordates have an actual heart like the vertebrate Chordates do.
