Some of the examples of phylogenetic tree are as following:

  • A notochord and jaws includes in birds and ray-finned fishes.  
  • Mammals and tortoises are closer to one another than lungfish and sharks are.  
  • Organic Descendants (d) have wings.  
  • Rays and frogs are columned vertebrally.  
  • A shared ancestor of all chordates is the organism (a).

Hence, the true options are B, D, F, E, H.
