Human History Evolution

The Big Ratchet is the story of the ratchets: the technologies and innovations, big and small, that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened.

No other life form on the planet has generated a brain like ours. How did a bundle of cells weighing just 1.2 kg give rise to conscious, self-aware beings capable of understanding time, language, mathematics and music, of exploring outer space and sequencing their own DNA?

Roland Ennos’ The Wood Age is a love-letter to the world’s most vital and yet most threatened material. It is the story of how wood has shaped our human experience from the earliest foragers to the modern four-poster bed. In a journey to appreciate how much it matters, Ennos takes the listener through four phases: the impact of wooded habits on the lives of primates, human emergence and the discoveries of fire and woodwork, wood’s role in an environment both pre- and post-industrialisation, and lastly, the possible future of wood in an increasingly technologised world.

Anzeer’s point had been buried for thirty-seven-thousand years. Before, it had been at critical moments in human history. When Harry 925 found it and felt its power he was certain it was the weapon Angelica had told him to expect. He hid it in his clothes.
