There were, he would point out as though it really mattered, fascinating similarities in eye development, despite the differences in the local spectrum. Here, let me show you. And twenty minutes later they were into the feeding habits of warm-water reptiles. Or mating procedures. Or the curious and as-yet-unexplained diversity of propulsion methods by certain inhabitants of one of the southern swamp areas. Particularly annoying was his habit of periodically asking Abdul whether he understood, whether he grasped what the change in refraction really implied.
