I call one worker with a machine outperforming 150 people without one an energy-and-technology-leveraged human. Energy-powered technology allowed a person to vastly outperform humans without it. Was that person 150 times more dexterous? Smarter? Faster? Stronger? The machine did the work, not the person, and energy made it all happen, not the equipment. Without energy to run it, machinery is useless, but without human-made technology, the energy was unavailable. Such machines would never have been without the available energy to run them.

The rocks used for Oldowan tools were already nearly the shape needed and were made by banging candidate rocks on a rock “anvil,” and the fractured rock’s sharp edge was the tool. Those first stone tool makers were largely still the hunted, not hunters, and stone edges would have been like claws and teeth that would have made scavenging predator kills easy in a way that primates had never before experienced. Modern researchers have used Oldowan tools to quickly butcher elephants. Sawing a limb from a predator kill and stealing it would have been quick and easy. Stone tools also crushed bones to extract marrow, and would have made harvesting and processing plant foods far easier.

The process took several thousand years at minimum, and has been called a border war with Neanderthals, while others have called it a genetic assimilation. The way that humans drove the megafauna to extinction, and then engaged in warfare as they were driving the megafauna extinction, seems to favor a violent end for Neanderthals, and the “blitzkrieg” of humans migrating across the length and breadth of Australia in a few thousand years was not in evidence for the migration/invasion around the Mediterranean’s periphery.
