Abstract

This is a long-overdue biography of the Huxleys: the Victorian natural historian T.H. Huxley ("Darwin's Bulldog") and his grandson, the scientist, conservationist, and zoologist Julian Huxley. Both T.H. and Julian suffered from depression, thinking and writing about the condition and genetic inheritance in highly curious ways. And between them, they communicated to the world the great modern story of the theory of evolution by natural selection. Because the grandson modeled himself so self-consciously on the grandfather, celebrated historian Alison Bashford writes seamlessly about these omnivorous intellects together, almost as if they were one very long-lived man whose vital dates bookended the colossal shifts in world history from the age of sail to the Space Age, and from colonial wars to world wars to the cold war. The myriad questions that the Huxleys grappled with make them the perfect dynasty-companions for time travel over the age of evolution: What is the nature of time and how old is the Earth itself? What is the connection between human history and natural history? How are humans animals and how are we not? What is the deep past and the distant future of humankind? Can and should we actively seek to improve future generations? What might the planet look like 10,000 years hence? This momentous biography traces the problems and wonders of the modern world that the Huxleys themselves raised, postured, and pondered over lives that spanned the age of evolution.
