You don't normally think of lizards as smart. OK, Godzilla figured out long ago that the Japanese military was impotent and he could attack Tokyo any time he felt like it, but your ordinary garden lizard didn't have much going on between its scaly ears.
Turns out lizards can do some basic problem-solving for food, and they remember the problem presented with it again the next day. Puerto Rican anoles, once they worked out by trial and error a problem where food was hidden under one of two caps, each a different color, would remember what color worked for them, and would pick out the right one on the first try a day later.
