When Vivian was less than a year old we went to see Lucy who was on an extraordinary visit to the Houston Museum of Natural Science. At 3.2 million years old, Lucy isn't human but close.
Historians and scientists assumed that human were the first animals to make tools. The oldest tools are crude stones called chopping tools found in Africa and have been dated back to 2.6 million years. The oldest member of our genus, homo, can be traced back to about that time. When Alu and I were in our early teens there was this beautifully bound coffee table book at home - "The Last 2 Million Years". We thumbed through it all the time. Nothing has changed much since that book was published. Things were settled.
Then a few years ago, a team of American archeologists on a field trip to Kenya took a wrong turn on a dry river bed as American tourists often do and discovered something. Their work was finally revealed at a meeting of paleontologists last month and published in Science. The oldest tools are now decidedly older - about 3.3 million years old.
So either tool making predates humans. Lucy and her friends were smarter than they look. Or there are older human fossils waiting to be discovered by some poor American who is directionally challenged.
Unless you are a creationist, this is literally a case of having to rewrite history books. Like the excellent one I am reading - Neil MacGregor's "A History of the World in 100 Objects". Object No. 2 is the Olduvai stone chopping tool and it's write-up will require some revision.
But my favorite object so far is another tool. We made more of it than any other tool. We probably may not have survived as a species without it. Not the iPhone. That has been around for 8 years. This tool remained the leading edge of technology for more than a million years. It is Object No. 3, the Olduvai handaxe. It is a much nicer and newer tool than the chopping tool. People started making this kind of handaxe a mere 1.5 million years back and we took it with us when we moved out of Africa to every part of the Old World. Amazing.
It is also amazing that Vivian and I can chat about this.
