Sure the Jaws ride at Universal Studios Orlando is one of the oldest movie themed theme park rides in the country. Sure, Bruce the shark is old and cheesy looking, but damn them for shutting it down. Jaws the Ride is a g.d. Orlando institution.
Super evolved, but unnecessary.
"But…" I hear you say already, "I like my jaw, and I think it’s pretty necessary. Without a jaw, how would I eat or give head?" But that’s just because you’re used to having a jaw, not because having a jaw is in any way necessary to life. And after studies of the evolution of the jaw, scientists still don’t know why jaws evolved, since they gave almost no advantage over jawless creatures and the jaw itself is pretty much unchanged since the beginning, across all animals that have them.
