Emirates Airlines has launched a chauffeur-less drone that will transport flyers between any location in Dubai and the city's main international airport.RETROGRESSIVEMeanwhile, here in Kenya, Oscar Sudi is reverse-evolving back to the Oldowan age when stones were the most technologically advanced tool available and headaches were cured by breaking your skull.

The million-year-old Oldowan chopper presented by a grad student became a prop for David Brower's talks, an illustration for his "sermon" on man's last-minute place in the seven days of creation.

OLDOWAN STONE TOOLS AND HOMININ COGNITION: WHAT CAN STONE AGE TECHNOLOGY TELL US ABOUT CONTEMPORARY LEARNING?

In the fourth cognitive stage, Mode 1 tool making, the Oldowan chopper or pebble tool (2.8 million years ago) added the cognitive dimension of the edge as a specific part of a rock and requires controlled iterative action--multiple flaking.

In addition, these pioneers possessed primitive stone tools such as cobble stone and flakes of Mode 1-type called Oldowan technology, as opposed to the well-developed ones the researchers expected.

We now call these ancient artifacts the 'Oldowan tool industry', the earliest precursors to the stone tools I found on Ohio farms.

Researchers have long thought that those cutting and digging implements, called Oldowan tools, were too advanced to have been the first stone tools.

"I have seen some of these artifacts in the flesh, and I am convinced they were fashioned deliberately." Wood said he found it intriguing to see how different the tools are from so-called Oldowan stone tools, which up to now have been considered the oldest and most primitive.
