The Evolution of Breathing: From Ancient Humans to Today

This chapter examines how modern humans have become poorer breathers compared to our ancestors, highlighting the contrasts in dental health and facial structure found in the Morton Collection at the University of Pennsylvania. It discusses the impacts of diet and industrialization on our anatomy, particularly how the shift to softer foods led to narrower mouths and breathing issues. The chapter also explores the health consequences of mouth breathing, including sleep disruptions and increased urinary frequency, prompting listeners to consider their own oral health experiences.
