By reshaping landscapes, our ancestors actively constructed the niches they inhabited. This process is an important aspect of evolutionary change,As humans evolved, the demands of the growing population, associated knowledge creation and energy use created aRevving up the Anthropocene engine The Anthropocene engine has been running for at least 8,000 years. It led to the rise of modern civilizations and ultimately to the environmental challenges we face today, including climate change.First, populations had to reach a critical number of people to successfully create enough knowledge about their environments that they could begin to actively and purposefully transform the niches they lived in.Successful agriculture was the product of such knowledge.
More energy supports more people. More people led to early settlements and, later, to cities. This allowed for task specialization and division of labor, which, in turn, accelerated the creation of more knowledge, which increased available energy and allowed population size to grow as well. And so on, and so on.
While the details of this process differ around the world, they are all driven by the same Anthropocene engine.
