Although humans are not alone as tool using animals, we are definitely the planet’s designated experts in the field. Our use of invention, or the innovation of altering an object or process in new ways, may be what truly defines us as a species. Every once in a long while, something is invented which changes, in some small way, the very nature of our lives. Over time, this has made us unique among the animals.
