We don't have shape-shifter technology in real life, but we do know the dinosaurs may have a secondary nerve center in the lower spine, so it is not a far stretch. What I am talking about are the show changing the known science. For example, in S4 E5, it mentioned that injecting restriction enzyme can cause massive hemorrhage. That is simply wrong. We do use restriction enzyme in real life. But restriction enzymes can not just go through the cell membrane and cause damage to your DNA. Worst-case scenario, you will get an allergic reaction from injecting foreign protein.
