MU Biologist Rex Cocroft studies animal communication, something he was drawn to at a very young age. Communication is crucial to life at many levels, occurring within a cell, between cells, or between organisms within social groups. “Once we reach the level of communication between individuals, not only is there the fascinating intellectual challenge of studying communication, but there’s also this tremendous aesthetic appeal – that the signals themselves are often beautiful: the songs of whales, the flapping of butterfly wings, the scents of flowers.” Beyond its inherent beauty, communication is very important for the biology of organisms, since the evolution of the signals has much to do with the evolution of the species itself.
