W. Tecumseh Fitch
W. Tecumseh Fitch is an American evolutionary biologist and cognitive scientist at the University of Vienna.
He studies the biology and evolution of cognition and communication, both in humans and other animals, and in particular the evolution of speech, language and music. In doing so, he concentrates on comparative approaches as advocated by Charles Darwin, i.e. the study of homologous and analogous structures and processes in a wide range of species.
