 Ultimately these 'atomic instincts' are incorporated into the 
 genome as part of the 'wiring diagram' for the nervous system. 
 Maybe we shouldn't be doing a GEnome project, but rather a 
 BEEnome project, since bees have a simpler nervous system,
 mayve we could actually locate the genetic loci which encode 
 hive-building?????
