Dave Gammon, Assistant Professor of Biology, presented his research on the evolution of culture in animals to the biology department at UNC-Greensboro on Wed 20 Feb. His talk was titled, “Social and ecological influences on the cultural evolution of bird vocalizations”. To summarize the presentation, he played a lot of interesting sounds recorded from black-capped chickadees, he presented data suggesting how and why this animal “language” changes over time, and he showed some parallels with human language.
