Most animal phyla belong to the clade Radiata. The origin of all extant animal phyla can be traced to the Cambrian explosion. Most deuterostomes have indeterminate cleavage, meaning that each cell produced by early cleavage divisions retains the capacity to develop into a complete embryo.Īll animals (including humans), plants and other organisms such as fungi and algae are Eukaryotes and share a common ancestor.Mar 18, 2011ĭo most animal phyla belong to the clade radiata? What do many organisms with Deuterostome development have in common?ĭeuterostomes have indeterminate development. Pseudocoeloms arose early in animal evolution and evolved into coeloms. Only a coelom is fully lined with mesoderm tissue.
What is the key difference between a coelom and a pseudocoelom? A coelom is a true body cavity, whereas a pseudocoelom is a false coelom that is not fully functional. What is the key difference between a Coelom and a Pseudocoelom? (Evidence that supports this includes the lack of true tissue in sponges and the close similarity between choanocytes and choanoflagellates.) Terms in this set (12) The animal phylum most like the protists that gave rise to the animal kingdom is _. What animal phylum gave rise to the animal kingdom? Which of the following statements correctly describes a characteristic of the phylum Platyhelminthes? They typically reproduce asexually. Which of the following statements correctly describes a characteristic of the phylum platyhelminthes? Which of the following statements is correct the origin of all extant animal phyla? What is the correlation between miRNA diversity and animal complexity? miRNA diversity and animal complexity are positively correlated. Is animal complexity correlated with miRNA diversity? Which statement about deuterostomes is correct? Which of the following statements best represents evidence supporting the leading hypothesis regarding the evolution of jaws in vertebrates? Both jaws and gill supports are derived from the same type of specialized embryonic cells.
Which of the following statements best represents evidence supporting the leading hypothesis regarding the evolution of jaws in vertebrates?
