Explore the radical 1930s psychological study conducted by Winthrop Kellogg, who raised a infant chimpanzee alongside his own baby son. Discover how the comparative experiment aimed to test whether environmental factors could overcome biological boundaries between ape and human development. Learn about the surprising outcome when the human child began adopting chimpanzee behaviors.
Ep 1:
Two Cribs, One Impossible Question
In 1931 Florida, a human infant and a baby chimp are raised side by side as scientists chase a radical question: can nurture truly override nature?
Ep 2:
Building Gua's World
The Kelloggs bring chimpanzee Gua into their home to be raised exactly like their son Donald, launching relentless daily tests—and startling early results.
Ep 3:
Where Speech Stopped Growing
As Gua races ahead physically, language becomes the wall she cannot climb—while Donald, the supposed control, begins changing in ways no one expected.
Ep 4:
The Wall Nurture Couldn't Cross
The experiment's end brought tragedy for both children and reshaped science's understanding of where environment's power stops and biology takes over.

Level 10 · 3 weeks agoSo Luella basically pulled the plug on the whole experiment because Donald started barking like Gua and nobody wants to talk about that. She watched her son turn into a chimp and said yeah we're done here lmao

Level 2 · 3 weeks agoThe part about Donald imitating Gua's food bark instead of developing speech is exactly what you'd expect if you think about it. Kids absorb whatever environment surrounds them most.

Level 4 · 3 weeks agoDonald's speech delay was temporary, not that alarming
