Humans have been asking this question for thousands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells and whole organisms to create new ones that could never have existed on their own.
In Creation, science writer Adam Rutherford explains how we are now radically exceeding the boundaries of evolution and engineering entirely novel creatures—from goats that produce spider silk in their milk to bacteria that excrete diesel to genetic circuits that identify and destroy cancer cells. As strange as some of these creations may sound, this new, synthetic biology is helping scientists develop radical solutions to some of the world’s most pressing crises—from food shortages to pandemic disease to climate change—and is paving the way for inventions once relegated to science fiction.
Meanwhile, these advances are shedding new light on the biggest mystery of all—how did life begin? We know that every creature on Earth came from a single cell, sparked into existence four billion years ago. And as we come closer and closer to understanding the ancient root that connects all living things, we may finally be able to achieve a second genesis—the creation of new life where none existed before.
Creation takes us on a journey four billion years in the making—from the very first cell to the ground-breaking biological inventions that will shape the future of our planet.
It is the history of who you are and how you come to be. It is unique to you, as it is to each of the 100 billion modern humans who have ever drown breath. But it is also our collective story, because in every one of our genomes we each carry the history of our species – births, deaths, disease, war, famine, migration and a lot of sex.
Evolutionary theory has long established that humans are animals: Modern Homo sapiens are primates who share an ancestor with monkeys and other great apes. Our genome is 98 percent identical to a chimpanzee’s. And yet we think of ourselves as exceptional. Are we?
In this original and entertaining tour of life on Earth, Adam Rutherford explores the profound paradox of the “human animal.” Looking for answers across the animal kingdom, he finds that many things once considered exclusively human are not: In Australia, raptors have been observed starting fires to scatter prey; in Zambia, a chimp named Julie even started a “fashion” of wearing grass in one ear. We aren’t the only species that communicates, makes tools, or has sex for reasons other than procreation. But we have developed a culture far more complex than any other we’ve observed. Why has that happened, and what does it say about us?
Humanimal is a new evolutionary history—a synthesis of the latest research on genetics, sex, migration, and much more. It reveals what unequivocally makes us animals—and also why we are truly extraordinary.
