Humility (2)

During the last, say 150 years there has been unrelenting and consistent technological change in nearly all areas – medicine, communications, travel, energy, the list is seemingly endless. It is almost unbelievable, actually. Somehow there seems to have been a parallel assumption that we humans have also changed greatly, maybe because we think we must have changed to bring forth all these marvels, and maybe, even more, many of us think that with all these new wonderful tools the measure of people, their character and behavior, must be changing rapidly as well. There has been, for at least six or seven generations, a steady belief in inevitable progress in all areas, including the character and behavior of humans. This is a huge, huge mistake, in my opinion, because human nature hasn’t changed despite all these technological breakthroughs. The evidence of our own eyes and memories, for those of us who have been around for eight or nine decades, is exactly the opposite, as is the historical record – we humans have been bad to each other, always and forever. Go way back, way way back, before farming, before towns and cities, the time of great ice and terrible animals, and humans barely hanging on in remote safe places. When a group invaded another group’s territory, back then, it seems they captured the women and children but killed off all the men, all of them, so there would not be retribution. Surely humans then, and in the years since, and today, Continue Reading →

Are we dumbing down?

I wonder if we as a species are dumbing down. Before farming (ie, dense settlements, crowds, and a need for administration) human bones we have recovered shows that skeletons were stronger and brains bigger. In fact the very recent discovery of that skull in northern China, maybe 150,000 years old, has a brain bigger than modern man’s. My guess is we had bigger brains because we needed to remember everything in order to carry forth learning and culture. We did this with stories, I am sure, stories as a way to encode memory for years, then for generations. Then with farming, and the development of a priestly class, writing developed, first used to catalogue the administration of commerce and materials, and to document religious structure and belief. Until very very recently – as in, the last say 500 years – only a tiny percentage of we humans could read and write; needed to read and write,. Then, about 400 years ago, education in the literary arts became more widespread, and now, in the 21st century, nearly everyone can read at some level. So for the last say four or five centuries humans began to store their memories and their data with writing and scrolls and books in levels great enough to see the broad development of libraries. Libraries, and palace records, documented what had been learned and exported all this information to ink and paper such that humans did not, any longer, have to carry everything around in their head.

Screamers (Humility # 2) on fishboats

When I was fishing on the East and Gulf Coasts a long time ago – actually a damn long time ago – there was a saying that wandered the docks. When boats tied up together in a port the guys working on the boats would talk to each other, on the dock or aboard boats or in the nearby barroom, catch up on scuttlebutt and gossip, tell lies. There was a phrase that floated around about some captains – actually at times more than some captains – and that phrase was, “He’s a screamer.” This meant that this person could not give an order without screaming the words, shouting, and often it seemed the case that no order was properly given unless it included at least two graphic insults. There were of course more captains, usually many more captains, who were not screamers, they were level-headed men (and these days they include many women too) who had the crew’s respect, who rarely had to give orders because the crew knew what was expected and jumped to. If you were lucky enough to be on a boat with a “good captain, meaning, someone who was all right to work for, this usually meant you were also on a boat that was well maintained, that carried the proper survival gear, where things usually worked, and where you made money. The crew members often became friends. I can name many boats which were based in New Bedford which had the same crew for Continue Reading →

The genetic plot thickens

When the Kennewick Man was discovered in Washington State a great argument ensued. Native tribes demanded that the bones remain with them, as an honored ancestor of 9,000 years ago. Others – non-Natives – argued the Kennewick Man carried “Western” traits (whatever the heck that means) and might have origins from Europe. A battle ensued. Along the way, of course, DNA analysis and genetic testing has evolved rapidly, such that today there are complete genomes of ancient peoples available from both the Old and New World. Recently, as the article below describes in fascinating detail, Kennewick Man has been confirmed as a true Native American ancestor, and his remains returned. It is still the strong belief, supported by evidence, that Native American peoples came from Eurasia, mainly Siberia, some 15,000 to 24,000 years ago. We have already forgotten that just two decades ago the STRONG belief was that nobody was in the Americas until the “Clovis” people appeared 12,000 years ago. As every year passes, dramatic rethinking is being forced by new finds: Ancient people reached the Americas at least 20,000 years ago, and maybe much earlier; Ancient peoples understood maritime seafaring and wandered widely, but during a time when sea levels were much lower such that all their sites are now covered; Ancient patterns of trade and resource exchange were complex and widespread, often covering thousands of miles; All during human development the climate has changed, some times rapidly, in enormous swings, equally as dramatic then as the current Continue Reading →

The Volcano Has Changed

The volcano in southwest Iceland has been erupting for 85 days more or less, and until very recently it was erupting every 7-12 minutes, flowing lava for a minute or two, then subsiding. The time between eruptions was long enough for the lava to cool on the surface and the mountain to become dark. Even yesterday, though the eruptions seemed to be a bit closer together, there were long pauses, several minutes, when the mountain went dark. No more. Something happened. Yesterday or the day before the top of the volcano, a sort of lid over the pool of lava, fell into the lava pool, and pool seemed wider afterwards. This evening when I turned on the video feed the lava flow was steady, changing very little minute to minute, flowing all the time. This means that the flow of lava emerging from the vent must be five to twelve times the flow when the eruptions were sporadic, and it seems in the night shots I see now that much of the lower lakes of lava and pooled material are glowing red and moving. Wow.

Razor stone…

I built this theory that during the last ice age, thousands of years, even tens of thousands of years before the accepted time of crossing the land bridge ( less than 15,000 years ago), people might have been in the Americas, living along the coast, sheltering on islands in glacial refugia away from the great carnivorous animals and near fish and marine mammals for food. Because, then, people must have been few in number, and because even in our earliest days humans knew it was healthiest to find mates not directly related to family members, I think it is fair to guess that bands of raiders went out and sought to steal people from other groups. This behavior has often been documented even in recent memory, as for example knowledge that First Peoples from way north in British Columbia sailed their great canoes south to the Strait of Juan de Fuca to capture women and slaves from Puget Sound tribes living along the shores of the strait. Evidence exists that ancient people were tremendous seafarers, surely able to leave the sight of land for fish, for travel, and while a coastline in an ice age might have long sections bounded by cliffs of ice, I speculate travel was possible, and frequent. The structure of the ice age world revealed in the Strong Heart Series is, of course, fiction, but as true as I could make it based on the research I did. It seemed to me then, and still does, Continue Reading →

Camping in the old days (1)

My dad was a serious hunter and camper. He was in the 10th Mountain Division during World War II, he called them the “ski troops” but then they invaded Italy and fought all the way to Germany and war’s end without donning a ski once, and when my sister and I were little kids we were camping in the back yard all the time, using gear he had brought back from the war or a tent his father had used years earlier. When I grew older I had a best friend older than me, Doug Bysiewski, and we would go down back into the fields and forests behind our house and pitch a tent and stay over night, as often as we could, exploring, finding owl nests, poking snapping turtles, messing around the UMass dump, and of course smoking. Once when I was about 10 or 11 there was a huge rainstorm and the tiny creek beside our house which drained into a wide swamp past the corn field, where Doug and I trapped muskrats every winter, flooded, enormously, such that the swamp was flooded, too, reaching all the way to our back yard, so my dad took the little 13 foot cedar canoe his dad, the serious hunter in our family, had built in the 1920s, and Doug and I took the 12 foot Old Town we had, and we pushed off from our back yard and followed the flooded rivers all the way to the Connecticut River ten Continue Reading →

The Fire Below….

Right now, May 24, 2021, there are at least two volcanoes erupting, one in Iceland and another in the Congo. Both eruptions are big and long lasting, producing rivers of lava. The video below is the Iceland volcano, which has been erupting for a couple of weeks. To me it is astonishing to see the molten rock flowing like water, even producing waves. Even more astonishing is the realization that beneath us lie cubic miles of hot molten magma. Here in the Pacific Northwest we live beneath a line of great volcanoes, one of which exploded 40 years ago, Mount St. Helens. It seems that these great volcano areas lie along the edge of a continental plate, such that when another great plate thrusts beneath it, huge earthquakes happen. There was an earthquake here in 2001, big enough to cause damage, shake buildings, cause higher buildings to sway back and forth, and this earthquake was nowhere the size of what everyone is predicting eventually. It seems the energy of the rock thrusting beneath other rock creates friction and heat, and magma, which will burst to the surface under pressure. There are other areas, like Yellowstone, which have been called “super volcanoes” because of the size of the magma chamber beneath. We have evidence of huge eruptions in the past, huge. We know about huge flooding of magma across thousands of square miles of land, just as we now know of enormous glacial floods in the past, not to mention asteroid Continue Reading →

Ancient Humans Thought Experiment (3)

I think there has been a lack of imagination about how ancient humans lived and survived. In addition to missing, until recently, the awareness that throughout human history humans have persisted through enormous climatic changes (one ice age after another), we have also imagined how ancient humans lived by comparing them to the few remaining hunter gatherer societies remaining on earth. By the time human studies and anthropology and archeology came into being as specific fields of study (no earlier than 1850 and really not until around 1900) most hunter gatherer groups had been decimated by disease, encroachment, and crowding. When I was in graduate school in 1970 some papers appeared contradicting the belief that ancient human groups spent all their time foraging for food, or hunting, frequently starving, always desperate and stressed. Studies of the Kalahari Bushmen in Africa, near the Kalahari desert in Botswana, demonstrated that in fact they lived pretty well – hunting one or two days a week, gathering foods a few days a week, and spending a lot of time socializing and telling stories. Researchers were also astonished to find that, once infant and childhood deaths were accounted for, adults lived to the same age as modern humans. So the belief was either that ancient tribes struggled always, or, perhaps, actually lived a nearly suburban life. While it may well be that ancient tribal groups lived very much as the few remaining hunter gatherers today live, what seems to be missing is that the major Continue Reading →
