Professor Tecumseh Fitch
Dept of Cognitive Biology, University of Vienna, Austria

I investigate human language viewed as a species-typical aspect of our biology, and attempt to understand it via comparison with other species’ cognition and communication systems (the comparative approach). The first step in doing so is to break language down to its components (the multi-component approach) and then ask which components are shared with which other species (or not). I present evidence for continuity in speech perception, most aspects of speech production, and of human conceptual semantics with animal cognition, and evidence for discontinuity when it comes to organizing principles of syntax (hierarchical structure) and potentially some aspects of semantics (pragmatic, theory-of-mind based production). I conclude that comparative research, guided by specific computational and mechanistic models deriving from linguistics and cognitive science, must play a central role in future attempts to understand language evolution.

CARTA: Domestication and Human Evolution - Tecumseh Fitch: The Domestication Syndrome and Neural Crest Cells: A Unifying Hypothesis

Play
Read more
The neural crest is a transitory embryonic tissue that, early in development, gives rise to a very diverse set of tissues and organs including pigment cells (melanocytes), bones, muscles and connective tissues in the head, and the adrenal gland. Tecumseh Fitch (Univ of Vienna) hypothesizes that the selection for tameness during early stages of domestication led to delayed maturation and reduced output of the adrenal component of the “fight or flight” response, via reduced neural crest input. This led, as an unselected byproduct, to other neural crest-derived tissues also being reduced, resulting in short snouts, smaller teeth, floppy ears, and changes in pigmentation (e.g. white spots).
