… 320,000 years ago "The first analysis of a new sedimentary drill core representing 1 million years of environmental history in the East African Rift Valley shows that at the same time early humans were abandoning old tools in favor of more sophisticated technology and broadening their trade networks, their landscape was experiencing frequent fluctuations in vegetation and water supply that made resources less reliably available. The findings suggest that instability in their surrounding climate, land and ecosystem was a key driver in the development of new traits and behaviors underpinning human adaptability. In the Oct. 21 issue of the journal Science Advances, an interdisciplinary team of scientists led by Richard Potts, director of the Human Origins Program at the Smithsonian's National Museum of Natural History, describes the prolonged period of instability across the landscape in this part of Africa (now Kenya) that occurred at the same time humans in the region were undergoing a major behavioral and cultural shift in their evolution. Potts and colleagues documented this behavioral and cultural shift in 2018 based on artifacts recovered at an archaeological site known as Olorgesailie. Decades of study at Olorgesailie by Potts' team and collaborators at the National Museums of Kenya have determined that early humans at Olorgesailie relied on the same tools, stone handaxes, for 700,000 years. Their way of life during this period was remarkably stable, with no major changes in their behaviors and strategies for survival. Then, beginning around 320,000 years ago, people living there entered the Middle Stone Age, crafting smaller, more sophisticated weapons, including projectiles. At the same time, they began to trade resources with distant groups and to use coloring materials, suggesting symbolic communication. All these changes were a significant departure from their previous lifestyle, likely helping early humans cope with their newly variable landscape, Potts said…" Main page link Amicalement Armand

So. I ordered some Top Secret models from Gaming Models for a game to be played Sunday 12/20. Craig pushed my order to the head of the line and shipped 12/8, with a tracking number. That tracking number has provided endless entertainment for me and Craig. It took 5 days to get from Akron Ohio to Allentown Pa. I got an update from USPS Tracking that it was out for delivery on Saturday the 13th. Nothing. Then, USPS kind of lost it. Maybe it wandered off. Daily checks had it "in transit to next facility". I think that's code for "Stop bothering me, kid!" Then, on Friday last, suddenly it was leaving Allentown for Scranton! 65 miles! Saturday update said I would get it Saturday! Sunday update put it at my local Hub! It's a half mile from my house! Just sitting there! Today, Monday the 21st, it's delivered. Note that the game was to be played on Sunday the 20th. "Fortunately" we got whacked with a big snow storm on Thursday, and I had to cancel due to the unavailability of parking. Game was moved back to Sunday the 27th. I guess one could say that they arrived in time for the game. Back to the models. Really nice, inexpensive models of the LVT-4 Buffalo. Crisp detail, come preprinted, one coat, my choice. Craig was willing to ship me another order if they didn't come in today, but that wasn't necessary. And don't get me started about the Hannah Glasse "Art of Cookery" book I sent my sister from Amazon. Last week she had an empty envelope dropped on her porch. Yes. Empty. That story hasn't concluded yet. |

Another order, this time for me. "Peckuwe", an obscure battle on the Ohio in the AWI. Now, I just received a notice that they're unable to deliver it. |

That's about 30 minutes from my house. Every year -- except this year -- there is a large living history event adjacent to the battlefield called "The Fair at New Boston." |
