300,000-YEAR-OLD MOROCCAN FOSSILS REWRITE OUR HISTORY

From Arizona Daily Star, June 8, 2017 by Malcolm Ritter

Human bones, approximately 300,000 years old, were unearthed in Morocco, thousands of miles away from the previous record-holder, in fossil-rich eastern Africa. These newly-discovered fossils show a mix of modern and more primitive traits. One of the scientists said that one might be able to see the face in modern times, but they are not just like modern humans.

The Moroccan fossils suggest that Homo sapiens may have reached its modern day form in more than one place within Africa. Previously, the oldest known fossils clearly from Homo sapiens were from Ethiopia, at about 195,000 years old.

"It’s not clear just when or where Homo sapiens came on the scene in Africa. Jean-Jacques Hublin (of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the College of France in Paris) said he thinks an earlier stage of development preceded the one revealed by his team’s discovery.

We evolved from predecessors who had differently-shaped skulls and often heavier builds, but were otherwise more like us than, say, the ape-men that came before them. Our species lived at the same time as some related ones, like Neanderthals, but only we survive…

"The Moroccan specimens were found between 2007 and 2011 and include a skull, a jaw and teeth, along with stone tools. Combined with other bones that were found there decades ago but not correctly dated, the fossil collection represents at least five people, including young adults, an adolescent, and a child of around 8 years old. Analysis shows their brain shape was more elongated than what people have today.

Hublin contends that the main story in human development is the change of the brain.

"When these ancient people lived, the site in Morocco was a cave that might have served as a hunting camp, where people butchered and at gazelles and other prey. They used fire and their tools were made of flint from about 25 miles away."

BENCH TIPS FROM BRAD SMITH

FANCY RIVET HEADS: For a nice-looking rivet head, use brass escutcheon pins. You’ll have perfectly rounded heads that are all the same size 3

and shape. The pins are a little hard to find, so try the best hardware stores first. Be sure to get solid brass pins, not brass plated steel. If unsure, test them with a magnet.

The pins are available online. Lee Valley Tools has them in 14 to 18 gauge and lengths from ¼ inch to 1 inch. Go to http://www.LeeValley.com (http://www.LeeValley.com) and do an item search on "brass escutcheon pin".

For best results, select a drill that gives you a hole with a close fit to the rivet. Trim the rivet to leave a little less than one diameter sticking out the back side. Place the head on a scrap of hard plastic on the anvil so as to not flatten the head. I prefer a ball peen hammer (with a small 3/8" ball) for setting the rivet.

EASIER PRONG SETTING: When setting stones in a prong mount, the tool is less likely to slip off the prong if you grind a groove into its face or rough up the face a bit with sandpaper. Some folks prefer a prong pusher for doing this, and others like a set of pliers.

The easiest way to create a slot on the pusher is with a file, and the easiest way to create a slot on one jaw of your pliers is with a cutoff wheel. Then rough polish the slot with a medium grit, knife-edge silicone wheel.

MINING IN COCHISE COUNTY

Excelsior Mining’s Johnson Camp Mine is set to go into production soon, with all their ducks in order. This is not slated to be an open-pit, unsightly mine, but will be an in-situ recovery project. This mine is considered feasible because it is in the copper porphyry zone, an extensive area in Arizona. The following picture, taken from the Excelsior (Gunnison) Mine Web site, shows the mine’s location.

There will be no open-pit mining, just drilling down below the water table to extract the copper from the porphyry. The company writes that there would be minimal damage to the landscape, and, when the copper runs out, the drill shafts would be pulled out and things would not look any different than before the work started.

The company’s home office is in Vancouver, Canada, but an office exists in Phoenix. If enough members are interested, we can ask a representative to talk at our September or October meeting.
