The Cave of the Trois-Frères: A Masterpiece…

Japan’s Paleolithic culture is followed from around 14,000 BCE (the start of the Jomon period) by a Mesolithic to Neolithic semi-sedentary hunter-gatherer culture, who include ancestors of both the contemporary Ainu people and Yamato people, characterized by pit dwelling and rudimentary agriculture.

Decorated clay vessels from this period are some of the oldest surviving examples of pottery in the world.

The Woolly Rhinoceros: A Survivor of the Ice Age

The woolly rhinoceros (Coelodonta antiquitatis), a dominant species across Europe and Asia during the Pleistocene epoch, was one of the last and most specialized members of the Pleistocene rhinoceros lineage. It thrived throughout the last glacial period, adapted to the frigid landscapes of the steppe-tundra biome that spanned the Palearctic ecozone.

Anatomy and Adaptations

• The woolly rhinoceros maintained a conservative body plan, similar to the earliest rhinoceroses from the late Eocene, while evolving specific adaptations to cold climates.
• Stocky limbs and thick, woolly fur helped it survive the harsh steppe-tundra conditions.
• Size and Build:
  • Length: 3 to 3.8 meters (10 to 12.5 feet)
  • Weight: 2 to 3 tons on average
  • Height: Up to 2 meters (6.5 feet) at the shoulder
• Horns and Skull:
  • Two keratin-based horns, with the larger anterior horn measuring up to 2 feet.
  • A smaller horn positioned between the eyes.
• Other Features:
  • Small ears, short, thick legs, and a robust, stocky body.
  • Cave paintings suggest some individuals may have had a dark band across their midsection, though this is not universal.

Fossil Evidence and Artistic Depictions

The external appearance of the woolly rhinoceros is known from:

• Frozen mummified remains recovered from Siberia, providing detailed anatomical information.
• Cave paintings created by early humans, though some depictions remain uncertain in terms of species identification.

Extinction and Discovery of a Complete Specimen

• The woolly rhinoceros went extinct around the end of the Pleistocene, likely due to a combination of climate change and human hunting pressure.
• Until the 20th century, its physical form was known only from prehistoric cave drawings.
• In a remarkable discovery, a completely preserved specimen (missing only fur and hooves) was found in a tar pit in Starunia, Poland.
• This specimen, an adult female, is now housed at the Polish Academy of Sciences' Museum of Natural History in Kraków, offering an invaluable glimpse into the anatomy and preservation of this Ice Age giant.

The woolly rhinoceros remains one of the most iconic Ice Age mammals, demonstrating how megafaunal species adapted to glacial conditions before ultimately succumbing to environmental and ecological pressures.

The Historical Range and Decline of the European Bison (Wisent)

The lowland European bison (Bison bonasus), also known as the wisent, once roamed extensively across the lowlands of Europe, from the Massif Central in France to the Volga River and the Caucasus. It may have also inhabited parts of Asiatic Russia, though evidence of this remains inconclusive.

Range Decline and Human Impact

• The expansion of human populations led to widespread deforestation, reducing the wisent’s natural habitat.
• As forests were cleared for agriculture and settlements, the bison’s range gradually contracted.
• Hunting pressure further accelerated the species’ decline, as it was prized for meat, hides, and sport.

By the early 20th century, the European bison was on the brink of extinction, surviving only in protected reserves and conservation programs. Today, efforts to reintroduce and conserve the species have been successful in several parts of Europe, though its range remains far more restricted than in prehistoric times.

The assemblages of Northern Germany’s Hamburgian tradition, contemporaneous with, but typologically different from, the Upper Magdalenian of France and Spain, are characterized by heavy flake scrapers, end scrapers on blades, borers, and obliquely shouldered implements, called Hamburgian points.

Bone and antler tools, from about 15,000 BCE, include small projectile points, long slender points, knives, knife handles, and single-row barbed harpoons.

The Hamburgians, like the French Magdalenians, are almost entirely dependent on migratory reindeer.

The Hamburgian tradition displays little of the artistic engraving displayed in the assemblages of the French and Spanish Magdalenian cultures.

Prehistoric South American sites include Lapa Vermelha IV, also in Brazil, which yielded the thirteen thousand five hundred-year-old skull of a female nicknamed Luzia, who died in her early twenties.

It is the oldest human skeleton found in the Americas.

Although flint tools were found nearby, hers are the only human remains in Vermelha Cave.

Some archaeologists believe the young woman may have been part of the first wave of immigrants to South America.

Her facial features include a narrow, oval cranium, projecting face and pronounced chin, strikingly dissimilar to most native Americans and their indigenous Siberian forebears.

Anthropologists have variously described Luzia's features as resembling those of Negroids, Indigenous Australians, Melanesians and the Negritos of Southeast Asia.

Walter Neves, an anthropologist at the University of São Paulo, suggests that Luzia's features most strongly resemble those of Australian Aboriginal peoples.

Richard Neave of Manchester University, who undertook a facial reconstruction of Luzia, described it as Negroid.

However, cranio-facial variability could be a component of genetic drift in Native Americans.

A comparison in 2005 of the Lagoa Santa specimens, with modern Botocudos of the same region, also showed strong affinities.

Interestingly, two ancient human skulls from Brazil's indigenous Botocudo people, known for the large wooden disks they wore in their lips and ears, belonged to people who were genetically Polynesian, with no detectable Native American ancestry.

The genetic evidence indicates either that Rapa Nui people traveled to South America or that Native Americans journeyed to Easter Island.

The findings suggest these Polynesians reached South America and made their way to Brazil, either landing on the western coast of the continent and crossing the interior or voyaging around Tierra del Fuego and up the east coast.

Settlements at two sites in the Andes—Pachamachay, Peru, and ...

...Tibitó, Colombia—return radiocarbon dates indicating habitation thirteen thousand nine hundred and thirteen thousand six hundred years ago, respectively.

The Page-Ladson prehistory site (8JE591), a deep sinkhole in the bed of the karstic Aucilla River (between Jefferson and Taylor counties in the Big Bend region of Florida), has stratified deposits of late Pleistocene and early Holocene animal bones and human artifacts.

A group of eleven artifacts found there has an average age of 15,405 to 14,146 calendar years Before Present (12,425 ± 32 14C years BP).

The earliest dates for artifacts recovered from the site are between one thousand and fifteen hundred years before the advent of the Clovis culture.

The site is the first pre-Clovis site discovered in southeastern North America.

Page-Ladson is about sixty meters by forty-five meters wide and ten meters deep.

Its significance is that the dating of the artifacts places humans at the location more than one thousand five hundred years prior to earlier evidence and challenges theories that humans quickly decimated large game populations in the area once they arrived.

A dramatic and rapid rise in global sea-levels of around fourteen meters is linked by coral off the South Pacific island of Tahiti to the collapse of massive ice sheets fourteen thousand six hundred years ago.

An Aix-Marseille University-led team, including Oxford University scientists Alex Thomas and Gideon Henderson, confirmed that a dramatic and rapid rise in global sea-levels of around fourteen meters occurred at the same time as a period of rapid climate change known as the Bølling oscillation.

The Bølling oscillation, a warm interstadial period between the Oldest Dryas and Older Dryas stadials, at the end of the last glacial period, is used to describe a period of time in relation to Pollen zone Ib—in regions where the Older Dryas is not detected in climatological evidence, the Bølling-Allerød is considered a single interstadial period.

The beginning of the Bølling is also the high-resolution date for the sharp temperature rise marking the end of the Oldest Dryas at 14,670 BP and the beginning of the so-called Humid Period in North Africa.

The region that will later become the Sahara is wet and fertile, its aquifers full.

During the Bølling warming high latitudes of the Northern hemisphere warmed as much as 15 degrees Celsius in a few tens of decades.

The team has used dating evidence from Tahitian corals to constrain the sea level rise to within a period of three hundred and fifty years, although the actual rise may well have occurred much more quickly and would have been distributed unevenly around the world's shorelines.

A leading theory is that the ocean's circulation changed so that more heat was transported into Northern latitudes.

A considerable portion of the water causing the sea-level rise at this time must have come from melting of the ice sheets in Antarctica, which sent a 'pulse' of freshwater around the globe.

However, whether the freshwater pulse helped to warm the climate or was a result of an already warming world remains unclear.

The Domestication of Dogs: Early Human-Canine Cooperation

By 12,000 BCE, humans had likely successfully domesticated dogs, marking one of the earliest known interspecies partnerships. While the exact timeline and process of dog domestication remain debated, it is widely accepted that human interaction played a crucial role in shaping the modern dog (Canis lupus familiaris).

The Timeline of Dog Domestication

• Genetic evidence confirms that dogs genetically diverged from wolves at least 15,000 years ago, though some researchers suggest an even earlier domestication event.
• Mitochondrial DNA studies and archaeological findings place the earliest domesticated dogs within a timeframe of 17,000–14,000 years ago, around the Upper Paleolithic-Pleistocene/Holocene boundary.
• The exact date remains indeterminate, with contradictory evidence complicating the debate.

How Did Domestication Occur?

There are two major hypotheses regarding how dogs evolved from wolves:

1. Active Domestication by Humans

   • Early humans may have intentionally raised and bred certain wolves for hunting, guarding, or companionship, leading to gradual domestication.

2. Self-Domestication through Natural Selection

   • Some wolves may have gathered near human campsites to scavenge leftover food.
   • Over time, wolves that were less fearful and more tolerant of humans would have been more successful in obtaining food, favoring traits that led to domestication.

Scientific Evidence: Archaeology and Genetics

• Archaeological findings provide evidence of dog burials and human-dog associations dating back more than 15,000 years.
• Mitochondrial DNA studies support the idea that dog domestication began at multiple locations, possibly in Europe, Asia, or the Middle East.
• Despite ongoing research, the origin and exact timeline remain controversial, with findings pointing to multiple domestication events or hybridization with wild wolf populations.

Significance of Early Domestication

• The domestication of dogs represents one of the earliest examples of animal domestication, shaping human hunting, security, and companionship practices.
• This relationship likely played a role in human survival and social organization, as domesticated dogs aided in tracking prey, guarding settlements, and forming deep bonds with humans.

Though many aspects of dog domestication remain uncertain, what is clear is that humans and dogs have shared an extraordinary evolutionary journey, forming one of the most enduring and successful interspecies partnerships in history.
