The Middle of the Earth, one of the twelve divisions of the globe, encompasses Africa down to its subcontinent, the lands and seas of the Mediterranean Basin and the Red Sea, the Canary Islands, and the Cape Verde Islands.

The northwestern boundary extends from south-central Germany along the Swiss border, encompassing all Swiss cities except Basel. It then separates southern France from northern France, continues through Spain, and divides Portugal at Setúbal, marking a north-south division within both countries. The boundary then extends into the Atlantic Ocean, where it distinguishes Madeira (a Portuguese territory) from the Canary Islands (ruled by Spain).

The northeastern boundary separates Alpine Austria from the rest of the country, then moves through the Balkans, roughly following the borders between:

• Hungary and Slovenia,
• Serbia and Croatia,
• Bosnia and Herzegovina, Montenegro, and Kosovo,
• Bulgaria and North Macedonia,
• Turkey-in-Europe and Greece.

From there, the line continues through western Turkey and Cyprus, dividing Syria and most of Lebanon from Israel and most of Jordan, and marking the separation between western and eastern Arabia.

The southeastern boundary follows the historic division between North and South Yemen, then extends through eastern Africa, delineating Mozambique from Zambia.

The fossil was discovered by archeologist Italo Biddittu and was nicknamed "Ceprano Man" after a nearby town in the province of Frosinone, eighty-nine kilometers southeast of Rome, Italy.

The age of the fossil is estimated to be between three hundred and fifty thousand to five hundred thousand years old.

An adjacent site, Fontana Ranuccio, was dated to 487,000 +/- 6000 years and Muttoni, et al., suggest that Ceprano is most likely four hundred and fifty thousand years old.

The cranial features on the bone seem to be intermediate between those found on Homo erectus and those of later species such as Homo heidelbergensis, which dominated Europe long before Homo neanderthalensis.

There is yet not enough material to make a complete analysis of the individual.

The Moderns are taller, more slender, and less muscular than the Neanderthals, with whom they share—perhaps uneasily—the Earth.

Though their brains are smaller in overall size, they are heavier in the forebrain, a difference that may allow for more abstract thought and the development of complex speech.

Yet, the inner world of the Neanderthals remains a mystery—no one knows the depths of their thoughts or how they truly expressed them.

The fearsome cave bear (Ursus spelaeus) likely became extinct around 27,800 years ago, according to recent fossil reassessments.

Rather than a single cause, a combination of factors is believed to have led to its extinction. While overhunting by humans has largely been dismissed—since human populations at the time were too small to pose a significant threat—evidence suggests that cave bears and humans may have competed for shelter, particularly in caves.

Mitochondrial DNA research indicates that the cave bear's genetic decline began long before its extinction, ruling out climate change-induced habitat loss as the direct cause. However, a recent DNA study suggests that cave bear populations started declining around 50,000 years ago, coinciding with an increase in human populations.

Unlike its close relative, the brown bear, the cave bear was highly dependent on a vegetarian diet, making it less adaptable to environmental changes. Additionally, evidence suggests that cave bears exclusively used caves for hibernation, unlike brown bears, which could hibernate in thickets or other natural shelters. This specialized hibernation behavior likely contributed to high winter mortality when suitable caves were unavailable.

As human populations gradually expanded, both Neanderthals and anatomically modern humans increasingly occupied caves as living quarters, reducing the availability of essential hibernation sites for cave bears. Over time, this competition for shelter may have contributed to their gradual extinction.

Interestingly, cave bears are rarely depicted in prehistoric cave paintings, leading some researchers to speculate that human hunters may have avoided them, or that their habitat preferences simply did not overlap with early human settlements.

The invention of writing was not a single event, but rather a gradual evolution, preceded by the use of symbols, possibly originating for ritual or cultic purposes.

Researchers from the University of Victoria in Canada suggest that Neolithic cave painters employed symbolism as a form of early communication.

"...Von Petzinger and Nowell were surprised by the clear patterning of the symbols across space and time—some of which remained in use for over twenty thousand years.

Their research identifies twenty-six distinct signs, which may represent the earliest evidence of a graphic code used by humans shortly after their arrival in Europe from Africa—or possibly even earlier, suggesting they brought this practice with them.

If confirmed, these findings would support the growing body of evidence that the so-called "creative explosion"—once thought to have occurred later—actually began tens of thousands of years earlier than previously believed.

Cultural practices associated with modern humans—such as the careful burial of the dead, the creation of elaborate cave art, and the decoration of everyday objects—emerge during this period, reflecting an increasing sense of ritual, symbolism, and aesthetic expression.

The rapid expansion of anatomically modern humans out of Africa, beginning around 60,000 years ago, appears to coincide with the development of new stone tool-making techniques.

These innovations, which define the Upper Paleolithic period, distinguish the stone tool culture of Homo sapiens sapiens from the previously similar technologies of Neanderthals and other archaic human groups.

Key advancements include:

• The production of long, narrow flake tools, known as blades, which could be fashioned into a variety of specialized tools,
• The emergence of bone and ivory artifacts, and
• The eventual development of clothing, often sewn together and adorned with beads.

These technological advancements likely played a crucial role in the success and adaptability of early modern humans as they spread across new environments.

Around 55,000 years ago, global weather patterns begin to fluctuate dramatically, shifting from extreme cold to milder conditions and back within just a few decades.

By 50,000 years ago, the Wisconsin glaciation (known in Europe as the Würm glaciation) is well advanced. Expanding ice sheets in North America and Europe push climatic zones southward, transforming the temperate regions of Europe and North America into Arctic tundra-like landscapes. Meanwhile, rain bands typical of temperate zones shift south, reaching as far as northern Africa.

Neanderthals and Climate Adaptation

The Neanderthals, well adapted to cold climates with their barrel chests and stocky limbs, are better suited than Cro-Magnons to retain body heat. However, the rapid and unpredictable climate fluctuations cause ecological upheavals, replacing familiar plants and animals within a single lifetime—a shift to which Neanderthals struggle to adapt.

One major challenge is the replacement of forests by grasslands during the Mousterian Pluvial, an effect of the last Ice Age’s climatic shifts. This change disrupts the Neanderthals’ ambush-based hunting techniques, making it harder for them to secure food. As a result, large numbers of Neanderthals likely perish due to food scarcity and environmental stress, with the crisis peaking around 30,000 years ago.

Neanderthal Burial and Final Strongholds

Despite their decline, Neanderthals appear to be the first humans to intentionally bury their dead, often in simple graves. The last known traces of Mousterian culture, though lacking human remains, have been discovered at Gorham’s Cave on Gibraltar’s remote south-facing coast, dating between 30,000 and 24,500 years ago.

Possible Scenarios for Neanderthal Extinction

Several hypotheses attempt to explain the disappearance of the Neanderthals from the fossil record around 25,000 years ago:

1. Complete Extinction and Replacement: Neanderthals were a separate species from modern humans and became extinct due to climate change and/or competition with Homo sapiens, who expanded into their territories starting around 80,000 years ago. Anthropologist Jared Diamond suggests that violent conflict and displacement played a role in their demise.

2. Interbreeding and Absorption: Neanderthals were a contemporary subspecies that interbred with modern humans, gradually disappearing through genetic absorption.

3. Volcanic Catastrophe: A Campanian Ignimbrite super-eruption around 40,000 years ago, followed by a second eruption a few thousand years later, may have severely impacted Neanderthal populations. Evidence from Mezmaiskaya Cave in the Caucasus Mountains of southern Russia supports this theory, with mitochondrial DNA (mtDNA) analysis showing a distinct Neanderthal lineage separate from modern humans.

Energy Needs and Survival Challenges

Neanderthals had higher caloric requirements than any other known human species. They required 100 to 350 more calories per day than an anatomically modern human male (68.5 kg) or female (59.2 kg). This higher energy demand may have made them especially vulnerable when food sources became scarce, further contributing to their extinction.

Ultimately, by 25,000 years ago, Neanderthals disappear from the fossil record, leaving behind traces of their culture—but no direct descendants in the modern human genetic lineage.

As humans develop more advanced skills and techniques, evidence of early construction begins to emerge.

Fossil remains of Cro-Magnons, Neanderthals, and other Homo sapiens subspecies have been found alongside foundation stones and stone pavements arranged in the shape of houses, suggesting a shift toward settled lifestyles and increasing social stratification.

In addition to building on land, early humans also develop seafaring technology. The proto-Australians appear to be the first known people to cross open water to an unseen shore, ultimately peopling Australia—a remarkable achievement in early maritime exploration.

During this period, Neanderthals are gradually being displaced as modern humans expand into Europe.

The slow pace of human migration into Europe suggests that Homo sapiens and Neanderthals may have been in continuous competition for territory over an extended period.

Neanderthals, with their larger, more robust frames, were likely physically stronger than modern Homo sapiens. Having inhabited Europe for over 200,000 years, they were also better adapted to cold climates, giving them a potential survival advantage in harsh Ice Age conditions.
