Evolutionary origins of bee dances
Article Abstract:
It has been established that bumble-bees use a rudimentary, but highly effective, recruitment system. A single successful foraging bumble-bee is able to use extended excitatory runs in the nest to gain the attention of the whole foraging force of the colony. The successful forager brings the odour of the food source to the nest, thus transmitting to the recruits information about the species of flower. No information is given about the location of the food. This may be because the advantage of communicating location does not balance out the cost.

The origins of Andean irrigation
Article Abstract:
An integrated floodwater and canal irrigation system in Tarata village in the Bolivian Andes was in use in AD 719 and apparently existed for thousands of years. An analysis of the sedimentology and geomorphology in the area indicates that a hybrid-style irrigation system is responsible for the layer of silt on the Tarata fan. Long term irrigation restricts the deposition of the coarse sediments to the canalized main channel but the fine sediment is dispersed to other parts of the fan surface.
