Then write that word, spelled correctly, on the line provided. The purpose of the notochord is to provide a substrate for organs to attach to and create a fixed structure and shape for the organism to take hold. These traits are observed at some point during the development of the organisms. This is a unique feature because most adult chordates will not exhibit these traits but instead will either lose them or the traits will be morphed into other systems serving new functions.

According to the cladogram, which organism is most distantly related to the human? There are three subphylum's which are Urochordata (Tunicata) or tunicates, Cephalochordata or lancelets, and Vertebrata (Craniata) or vertebrates. As they mature, they lose the ability to swim and anchor themselves to a rock or similar hard surface. 29.1D: Characteristics of Vertebrates - Biology LibreTexts The Cephalochordata (cephalo meaning 'head' and chordata meaning 'cord') also have no brain, although they do have a notochord and a nerve cord and very simple circulatory systems. As embryos, they are quite similar, however, these animals are very different from each other as adults. They hypothesized that the transitional fossils were in sedimentary rocks older than 365 million years ago, when the first tetrapods appear in the fossil record. Tunicates also do not have brains, which is a unique feature for chordates. Animal Kingdom Flashcards | Chegg.com D).
