How We Discovered Germs

From Origin Of Everything.

Humanity didn’t always know about the invisible viruses, bacteria, and microbes that can cause disease. But that doesn’t mean we didn’t come up with some truly bizarre ideas. From the four humors and miasma theory to bloodletting and trepanation (aka literally drilling holes in people’s heads), Danielle traces humanity’s winding road to the Germ Theory of Disease that revolutionized the medical profession.

Origin of Everything is a show about the undertold histories and cultural dialogues that make up our collective story. From the food we eat, to the trivia and fun facts we can’t seem to get out of our heads, to the social issues we can’t stop debating, everything around us has a history. Origin of Everything is here to explore it all. We like to think that no topic is too small or too challenging to get started.
