Reimagining The Inner Ear: A Morphometric Modeling Approach For Establishing Shape Change In The Evolution Of The Human Otolith System, Christopher M. Smith
Dissertations, Theses, and Capstone Projects
Our sense of balance is among the most central of our sensory systems, particularly in the evolution of human positional behavior. The peripheral vestibular system of the inner ear comprises the organs responsible for this sense; the semicircular canals (detecting angular acceleration) and otolith organs (utricle and saccule; detecting linear acceleration, vibration, and head tilt relative to gravity). The vestibular organs are often considered a single system, with most research focusing on the semicircular canals. The otolith organs, by comparison, remain largely unexplored despite their central role in balance. Consequently, this lack of knowledge limits understanding of vestibular functional morphology …

Dispersal is a fundamental aspect of primates’ lives, influencing population connectivity through gene flow, driving community structure and assembly, and having important consequences for adaptation and speciation. Primates disperse within an environmental context, with both intervening and local environmental factors affecting the motivation, capacity, timing, and success of dispersal at all phases. Direct evaluations of primate dispersal are challenging given the rarity of dispersal events and the large distances that animals often settle from their departure site, therefore indirect measures– such as the use of population genetic data– are more common.
The field of landscape genetics enables researchers to combine …
