“Why Do We Have Different Blood Types?”

About this episode

Roxie Robinson explores the origins and significance of different blood types in a storytelling format.

Ever wonder why your medical form says “A positive” or “O negative”—and what that even means? In this rainy-night episode of Voices of Discovery , Roxie pours a cup of coffee and unpacks the strange, funny logic behind our blood types. From Karl Landsteiner’s 1901 discovery to the rare “Bombay phenotype,” she turns medical science into late-night storytelling—complete with fainting anecdotes, apple juice, and a few too many coffee refills. It’s biology explained like a chat with a friend: curious, a little clumsy, and full of “wait—what?” moments. Discover how evolution wrote survival codes into our veins, why variety keeps us alive, and why O-negative might sound dramatic but isn’t. Stay curious—and maybe eat before donating.
