Fire changed everything. In this episode of History of Hunger: How Food Made Humanity, host Lisa Rolen explores one of the most transformative innovations in our evolutionary journey: the mastery of fire. As early hominins adapted to life on the ground and moved beyond the fruit-rich diets of their ape ancestors, new foods—and new challenges—drove remarkable change.

Journey alongside Homo erectus, one of the greatest pioneers in our family tree, to discover how cooking unlocked more calories, fueled the growth of larger brains, reshaped the human body, and forever altered the course of evolution. Learn how our ancestors didn't just adapt to their environment—they began to transform it.

Sahelanthropus tchadensis

Travel back seven million years to the ancient forests of Chad, where the story of humanity begins. In the premiere episode of History of Hunger: How Food Made Humanity, host Lisa Rolen explores the world of Sahelanthropus tchadensis, one of our earliest known ancestors. Using fossil evidence and environmental clues, she reconstructs the landscape these early hominins called home and examines the foods that sustained them.

Discover how the search for nourishment may have influenced the evolution of upright walking, setting our ancestors on a remarkable new path. This episode introduces the central idea of the series: that hunger—the relentless pursuit of food—has been one of the greatest forces shaping human evolution and our shared history.

In this episode of History of Hunger: How Food Made Humanity, host Lisa Rolen follows our ancient ancestors as they take one of the most significant steps in human history: leaving the safety of the trees for life on the ground. As shifting climates transformed dense forests into open savannas, early hominins faced a new challenge—finding enough food to survive in an increasingly harsh environment.

Picking up where Toumaï's story left off, we explore how our bipedal ancestors adapted to dramatic geological and environmental change by expanding their diets and embracing new ways of foraging. Discover how millions of years of resilience, adaptation, and innovation helped shape the evolutionary path that ultimately led to modern humans.
