The commission follows the success of 2018 Comedy Short pilot Sara Pascoe Vs Monogamy. A semi-narrative comedy, it saw Pascoe factually exploring the topic of monogamy through scripted scenes and to-camera elements.
BBC Two describe the new series as "about family, relationships and biology", explaining: "The award-winning comedian subverts the traditional sitcom format by combining her eccentric characters, surreal moments and factual insight."
Producers say: "Sara Pascoe doesn't know why everyone else in the world is pairing up and having babies and sets out on a mission to understand them. She tries to prove that romantic love is mere chemicals and conditioning and doesn't deserve our respect. This conflicts a little with preparations for her sister's wedding, and her best friend's first pregnancy.
"The show is a full-hearted, full-brained approach to narrative comedy with characters that are full of life (apart from one ghost)."
Both the pilot and the new series are inspired by Pascoe's fascinating with anthropology, a subject upon which she has now penned two books: Animal: The Autobiography of a Female Body, and Sex Power Money, which will be published next week.
Sara Pascoe says: "I'm obsessed with family dynamics, sex, hope and the reasons underlying why humans behave as we do. My new series gives me a chance to explore all of these things in a funny, silly way, buoyed up by the research I've done for my two books."
Simon Pegg, Stolen Picture co-founder, said: "We're thrilled to be collaborating with Sara at Stolen Picture. She is without doubt, one of the sharpest minds and the funniest voices working in comedy today."
