Evolution (2026)

S1E2 The Ostrich

Reproduction has driven life on Earth for billions of years, and Chris Packham traces that epic story to answer a strange question: why does the ostrich lay the largest egg of any creature alive? Along the way, he uncovers the unexpected origins of sex itself, the evolution of the egg, and the remarkable rise of birds—all of it unfolding inside a single, fragile shell.
