The above link takes you to the opening essay of the
New York Times Magazine, Innovations Issue of June 9, 2013. The answer to the Times' rhetorical question about the greatest invention in history shouldn't surprise you. No, it isn't the printing press with movable type pictured above. The greatest invention ever was the first
stone chopping tools used by our ancestors 2.6 million years ago.
Olduwan Stone Chopping Tools, East Africa
These simple, modified pieces of rock in themselves are not so great to us modern humans when we compare them to subsequent inventions, innovations, and discoveries. It is true that fire usage, metal tools, the wheel, writing, mathematics, architecture, industrial manufacturing, electricity, the internal combustion engine, airplanes, atomic energy, medical science and technology, electronic computation, and others have been greater in terms of their power to manipulate the environment and their ability to improve human living conditions.
The greatness of these first
hominin (humans and their close extinct relatives) tools is in what they contributed to if not on their own precipitated - a new type of survival strategy in the natural history of animals commonly known today as "human cultural adaptation." These rudimentary tools our ancestors made, used, became dependent on, and gradually improved upon stand as our most important invention, ever. The subsequent impact of this new hominin way of life of which tool use was inseparable is still being powerfully applied to Earth, its environment, and all its life forms.
Stone chopping tools, used for butchering scavenged carcasses in East Africa 2.6 million years ago, are the oldest of our ancestors' tools to be preserved and later discovered in the archaeological record. Stone tool manufacture and usage helped initiate an unprecedented evolutionary adaptation in the natural history of animals. Hominin cultural adaptation did not emerge suddenly or fully formed. It is a set of innovations in
hominin evolution comprised of the following: tool manufacture and reliance, upright walking, high protein consumption, social group innovations, increased brain size, and language. It is this adaptation complex - an ecological-behavioral niche that we gradually created and continue build upon - that allowed us to survive and upon which we still depend today.
This complex is an emergent baseline bio-cultural foundation that made possible and sped up the emergence of all subsequent human inventions, innovations, and discoveries. Without the advent of this tool-centered adaptation complex the subsequent social, technological, and scientific advances humans have made would have been unlikely if not impossible.
