Phylum Chordata<\/strong><\/p>\n

 <\/p>\n

Human beings belong to a group of animals that all have backbones or ____________. This group is called the ____________, and is a “subphylum” of the phylum _________.<\/p>\n

Classification of Chordates<\/u><\/strong><\/p>\n

There are 3 subphyla in phylum Chordata<\/p>\n

    \n
  1. ____________________ (uro = “__________”)<\/em><\/li>\n
  2. ____________________ (cephalo = “__________”)<\/em><\/li>\n
  3. ____________________ (vertes<\/em> = “__________”)<\/li>\n<\/ol>\n

     <\/p>\n

    The first two phyla of invertebrate chordates represent an evolutionary transition between ______________ and ______________<\/p>\n

    Four Characteristics of Chordates:<\/u><\/strong><\/p>\n

    All animals in Phylum Chordata have these 4 characteristics at some point in their lives:<\/u><\/p>\n

    1. Most chordates have a ________________\n
        \n
      • the backbone evolved from the _______________ – a stiff flexible rod made of cartilage that runs along the back<\/li>\n
      • ALL chordates have a notochord at some point during their development<\/li>\n
      • in _______________ the notochord becomes the ________________<\/li>\n
