We aim at understanding the evolutionary scenario of acoustic communication by investigating the hypothesis that acoustical communication in terrestrial animals originated from noises that are contingent with breathing or gestures associated with predation or feeding. We are developing an evolutionary model of virtual creatures composed of blocks in a 3D physically simulated environment. Sounds are generated by physical contact of virtual creatures, which are perceived by and possibly affect the other creatures. This paper is to clarify whether and how an acoustic structure around distributed resources can affect the evolution of virtual creatures. The creatures within a distance of fixed radius from a resource block can equally share the amount of the resource. We conducted experiments with three settings of the resource radius and found that the population progressively evolved to share the resources by listening to sound from the sound source around resources.
