The Mysterious Waggle Dance

→ by Danieru
"Radar has helped resolve a long-standing controversy about the purpose of a strange dance performed by bees, Nature magazine reports.

The famous "waggle" dance contains information about the whereabouts of nectar, just as was originally proposed in the 1960s, scientists now claim.

The theory met with scepticism, partly because people did not believe bees could decode such a complex message. But now radar tracking has proved they do follow waggle dance instructions."
Once again the seeming overlying simplicity of nature hides an undercurrent of complexity. Not only does the hive of bees 'self' organise, but this evidence would suggest that individual bees also have some sense of themselves. To understand the instructions from one bee they would have to have at least one piece of rather incredible former information:

The bee doing the dancing is another entity separate from themselves.

This may not seem much, but it takes human children around 2 years before they can recognise that there are such things as other entities. If one child in a room of babies starts crying then more often than not the other babies will start to cry too, because they have no sense that the crying is being uttered from someone other than themselves. This empathy for others can also be seen in the first few hours after birth as babies will replicate facial expressions acted out by those around them.

The fact that one bee can compute the information attained by another and act on it individually is quite astounding. This does not imply of course that a bee has a deep sense of 'self', but 3rd person observation would suggest that the low level, individual behaviour the bees exhibit combines to produce the higher level organised system obvious in the hive as a whole. This, I suggest, is no different from human society. We are simply bees in a hive following simple rules which, from a higher perspective, seem to produce highly complex patterns of behaviour.

Check out this post I made a couple of months ago about complexity arising from ant colonies (and more specifically how ant colonies can 'learn' from past mistakes). Nature has a whole bunch of tricks up its sleeve (full article at link below).

Another cool fact about bees. When one bee determines that there is a threat to the hive, he/she alerts the other bees by releasing a pheromone and using its wings to spread that pheromone into the air. The other bees, upon detecting that pheromone, will then follow the first bee to the threat, which allows them to swarm.

I am fascinated by insect colonies for many reasons, but mainly from a theory of mind stance (sounds weird i know).
Does a bee hive or an ants nest have an existent 'self' that regulates the system? One would assume not, but it is hard to explain the controlled behaviour and learning ability of such a system without one. Unless that is we reject the idea of the self altogether, and just admit that autonomous individuals working to simple laws can create the effect of a centralised self.

This, of course, could rule out the self in humans too (afterall our brain is just a system of interconnected, individual neurons).
