The Red Queen

In the High Hide, Levine and Malcolm watch the herbivorous dinosaurs grazing and drinking  across the field; Levine notes their spacial arraingment and believes its a sort of defense perimeter. Below, Eddie finishes reassembling a spherical cage that Levine explains is a sort of shark cage, but for dinosaurs. The cage is fastened to the bottom of the High Hide and if any aggressive dinosaurs wander too close to the Hide, people on the ground can get into the cage for protection. Levine, however, believes that the pungent odor of the ferns being used to camoflage the High Hide (which are mildly poisonous) will deter any of the herbivores from coming too closely. Levine then continues on with his theory that modern-day plant defenses are the result of plants defending themselves from over-grazing from dinosaurs.

Noting that despite the abundance of apatosaurs, most of the trees seem relatively intact and not denuded as one would expect; Levine theorizes that the apatosaurs don't actually eat from the tops of trees as one would expect due to the physical stress of having such a long neck (breathing issues, pumping blood up such a long neck) but rather eat from the lower branches and use their neck as a sort of counter-balance for when they use their tails as a weapon of defense. Malcolm interjects that there is something even more remarkable about the dinosaurs they've seen; none of them have attained true adulthood. Levine is unconcerned, believing that dinosaurs simply need more time to grow. Malcolm doesn't believe that explanation for a second and throws Levine's arrogance back in his face by stating that the answer is obvious, much to the enjoyment of Kelly and Arby. Levine, annoyed, states that it could simply be due to being constrained on the island or that they were engineered to be smaller than the fossil record dinosaurs. Malcolm concedes that "Maybe you are right. But then again, maybe you are not."
