Genetic World

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.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

As the oft-repeated and invariably accurate pearl of wisdom goes, a dog truly is man's best friend. For a long time, people have almost universally loved dogs, and it seems to have been that way for at least tens of thousands of years.

This bond can be demonstrated by the mere existence of pet keepers who unironically refer to themselves as “dog parents,” not merely “dog owners”.

Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colors of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve features that make them more sexually attractive and reproductively successful. But if Darwin explained why sexual beauty evolved in animals, he struggled to understand how.

Kalin Taylor is on the path to success. He's just won a scholarship to the prestigious Sanderson College of Arts and Science to study medicine. He's also about to do something very, very stupid in the name of becoming one of the 'in' kids at college. It sounded simple at the time. Sneak into a branch of the top-secret, interstellar scientific company GenTech, take a photo of the genetically engineered creature Project Tau that's supposedly inside, and sneak back out again. Cue membership of the college frat house, cue popularity and an improved lifestyle, right?

It is indisputable that human intelligence makes our species stand out from other lives on Earth. Our brains, much more than our muscles, explain our successes in development, as well as our sometimes devastating effects on the planet. Our modern brain is an evolutionary feat in development for over 520 million years and is the key to everything that makes us the entirety of humanity. But while the human brain is remarkable, what happens if people stop being intelligent?
