Things are getting pretty scary here now. In the last two days, I have read reports that tend to make me wonder if indeed humans are as smart as they think. When you see what a mess humans have made of the world, I suppose that it is no wonder to question that.
Elephants can hear with their feet? It seems that they can do this over long distances by pounding on the jungle floor. If that isn't amazing enough, it seems that they can also recognize each other by the sounds their feet make. If they get warnings from a reliable source, they believe them. If these warnings are from a questionable source, then they ignore them. Too bad that humans cannot always do that. If they could pull this off, all the politicians would be in another line of work.
Now, the best one for today is that cockroaches can learn things. These little beasts have been around for many centuries, so is it any wonder that they can learn? It seems that like Pavlov's dog, they can salivate when a repeatable stimulus is presented to them. If a cockroach smells an odor when being fed a sugar solution, they learn to associate this odor with feeding. Then, when some sneaky scientist turns the odor machine on but leaves off the sugar solution, they salivate. Salivate?? Who would like to be the guy who runs the saliva measurement machine? "What does your dad do?" "He runs the spit measurement laboratory." Can't you just see a cockroach pondering the theory of relativity?
