Minerva Thalyss uses her micronaut to travel into the microbiome of her sister Fleming. Meanwhile, in the real world, Theda teaches Michiel a valuable lesson in biology. Where to start? The tree of life. We learn that every living thing shares the same ancestor. You think you're 'all human'? Guess again.

Biopolis - into the microbiome is created by Michiel van Poelgeest for the Max Delbrück Center. Script consulting by Jeff Emtman, additional narration by Colette Kinsella.
