The Beginnings of Man -Part 1
The nature of Man has evolved over millions of years, changed by environmental conditions, by the response of his instinctual nature and by the actions of his ego. Man’s inner characteristics are altogether different from the ancestral root which governs other species. Why then is he so different?https://tonyaholisticblog.com/2026/08/31/the-beginnings-of-man-part-1/

"What Really Killed the Mammoths? New Evidence Points to Exploding Comet 13,000 Years Ago
Evidence from key archaeological sites suggests a major cosmic explosion may have reshaped the climate and ecosystems of the late Pleistocene.
(. . .)
For the past couple of decades, Kennett and fellow proponents of this hypothesis have been gathering evidence that increasingly supports it, including a 'black mat' layer in the sediment at many sites across North America and Europe — indicative of widespread burning. Additionally, they have uncovered a growing list of impact proxies, which include unusually high concentrations of rare minerals that are common in comets, such as platinum and iridium, and mineral formations indicative of extremely high temperatures and pressures, such as nanodiamonds and metals and minerals that have melted, cooled, and hardened again, including metallic spherules and meltglass.
Thanks to advances in technology, the team is homing in on another proxy that is considered the crème de la crème of cosmic impact evidence: shocked quartz — grains of sand that exhibit deformations due to extreme heat and temperature. In samples from the three North American archaeological sites — Murray Springs, Blackwater Draw and Arlington Canyon — the researchers identified quartz grains with telltale cracks, some filled with melted silica. They used a variety of techniques, including electron microscopy and cathodoluminescence, to confirm that the quartz grains had been shocked at extremely high temperatures and pressures, far beyond what could have been accomplished by volcanism or ancient human activity."

Lake Agassiz (Paleogeography 🦕)
Lake Agassiz was a large proglacial lake that existed in central North America during the late Pleistocene, fed by meltwater from the retreating Laurentide Ice Sheet at the end of the last glacial period. At its peak, the lake's area was larger than all of the modern Great Lakes combined. It eventually drained into what is now Hud...

"Researchers analyzed sediment cores extracted from the seafloor of Baffin Bay near Greenland, finding indicators of a cosmic impact event inside the layer that correlates to the Younger Dryas. The findings, published August 6 in the journal PLOS One, suggest that a comet—or its remnants—exploded in Earth’s atmosphere at around the same time that this 1,200-year-long cold snap began.
A controversial hypothesis
The study offers new support for the Younger Dryas Impact Hypothesis. In 2007, researchers proposed that fragments of a disintegrating comet or asteroid struck Earth around 12,800 years ago, triggering wildfires across North America. Such a calamity would have produced enough soot and ash to blot out the Sun and plunge the Northern Hemisphere back into a colder state.
It’s an elegant explanation, but a highly contested one. Researchers haven’t found an impact crater that would prove this event took place, so proponents largely rely on geochemical evidence found in sediment layers that date back to just before the Younger Dryas began.
Amid a lack of definitive evidence for the Younger Dryas Impact Hypothesis, most experts instead subscribe to the Meltwater Pulse Hypothesis, which suggests that a deluge of freshwater from the melting ice sheet that covered most of North America during the Pleistocene temporarily interfered with Earth’s heat-transporting ocean currents. Previous geochemical evidence from ocean sediment cores supports this idea, but scientists have yet to determine the exact route taken by this apparent flood.
Searching for impact clues
The authors of this latest study, led by University of South Carolina archaeologist Christopher R. Moore, suggest that both hypotheses may be true. 'The [Younger Dryas Impact Hypothesis] is often cited as an alternative to the Meltwater Pulse Hypothesis,' Moore said in an interview with PLOS One. 'What many don’t understand is that the YDIH proposes the impact event (potentially involving many thousands of impacts and airbursts globally) would destabilize the glacial ice sheet in the Northern Hemisphere, leading to the collapse of massive glacial meltwater lakes and subsequently shutting down the ocean’s conveyor belt.'"

The findings, reported by University of South Carolina scientists, involve the discovery of several examples of direct evidence that Earth experienced a series of impacts from a disintegrating comet 12,800 years ago, which caused a period of cooler global temperatures lasting more than a millennium."

"Analysis of ocean sediments has surfaced geochemical clues in line with the possibility that an encounter with a disintegrating comet 12,800 years ago in the Northern Hemisphere triggered rapid cooling of Earth's air and ocean. Christopher Moore of the University of South Carolina, U.S., and colleagues present these findings in the journal PLOS One on August 6, 2025.
During the abrupt cool-off—the Younger Dryas event—temperatures dropped about 10 degrees Celsius in a year or less, with cooler temperatures lasting about 1,200 years. Many researchers believe that no comet was involved, and that glacial meltwater caused freshening of the Atlantic Ocean, significantly weakening currents that transport warm, tropical water northward.
In contrast, the Younger Dryas Impact Hypothesis posits that Earth passed through debris from a disintegrating comet, with numerous impacts and shockwaves destabilizing ice sheets and causing massive meltwater flooding that shut down key ocean currents.
However, the impact hypothesis has been less well supported, lacking any evidence from ocean sediments. To address that gap, Moore and colleagues analyzed the geochemistry of four seafloor cores from Baffin Bay, near Greenland. Radiocarbon dating suggests the cores include sediments deposited when the Younger Dryas event began.
To study them, the researchers used several techniques, including scanning electron microscopy, single-particle inductively coupled plasma time-of-flight mass spectrometry, energy dispersive spectroscopy, and laser ablation inductively coupled plasma mass spectrometry.

"In the study, 'At the far end of everything: A likely Ahrensburgian presence in the far north of the Isle of Skye, Scotland', published in the Journal of Quaternary Science, researchers conducted a field study to assess climatic, environmental, and sea-level contexts surrounding the newly discovered Late Upper Paleolithic site at South Cuidrach on the Isle of Skye.
Evidence from South Cuidrach and Sconser challenges assumptions about human presence in western Scotland during the Younger Dryas.
Identification of Ahrensburgian-type artifacts on Skye suggests a population may have adapted to extreme conditions. A people who originated in the mainland of northwest Europe, crossed Doggerland into Britain and eventually felt at home at the far end of everything."

🏴 **At the far end of everything: A likely Ahrensburgian presence in the far north of the Isle of Skye, Scotland**
“_ he people who made these artefacts originated in the mainland of northwest Europe, crossed Doggerland into what is now Britain, and eventually reached the far north of the Isle of Skye. Here, they adapted to live in a fragmented, fluctuating, and volatile environment amid melting glaciers, mountains, and oceans—vastly different from the low-lying environments of their homelands on the northwestern edge of the Great European Plain._”

Did the wind-driven parts stop during deglaciation before the #Holocene?
#YoungerDryas
https://en.wikipedia.org/wiki/Younger_DryasI guess not.
Would Marotzke or Latif say, AMOC "collapsed" back then?I heard oceanographer Mojib Latif say on German radio & TV, he doesn't see #AMOC having a tipping point at all. Is the wind thingy the semantic reason for such an opinion?
