  10. Sir I have a doubt from this chapter. Actually this one is not discussed in ur lectures yet but I was reading this thing. Nd I want to clear this doubt as soon as possible. So in the chapter animal kingdom(ncert); in the page 55 there is a line that all vertebrates are chordates but all chordates are not vertebrates. Because the notochord is replaced by vertebral column in the adults. In the next page for class chondrichthyes it is written that their notochord is persistent throughtout their life. So how is this possible bcoz if chondrichtyes is a vertebrate than their notochord should be replaced. Ryt?? So it is a big mistake of ncert or that is an exception?
