The Tobo Bottleneck
[related: Lesotho]
In the year 72,000 BC, the Tobo supervolcano erupted for 13 days, blotting out the sun for almost four years and reducing the worldwide human population to less than 1000 individuals. In the aftermath of the volcano, Homo sapiens demonstrated a torrid acceleration of cognitive and cultural complexity, as evidenced by a suite of technological and behavioral innovations - advancements indicative of a marked enhancement in symbolic thought, social organization, and adaptive strategies including but not limited to:
- Levallois Technique Refinement: The refinement of the Levallois flake production method, a sophisticated stone tool-making technique allowing for the efficient production of uniform products.
- Microlithic Technology: Microliths hafted onto wooden or bone handles, creating composite tools that enhanced hunting and processing efficiency.
- Pyromancy of Silcrete: Evidence from Pinnacle Point demonstrates the intentional use of heat treatment to improve the workability of silcrete, a fine-grained stone, representing one of the earliest known examples of pyrotechnology.
- Ochre Processing and Symbolic Use: The widespread use of ochre, a naturally occurring pigment, for symbolic purposes. In Blombos Cave, near modern day Lesotho[1], ochre pieces engraved with abstract patterns have been recovered, suggesting symbolic representation verging on proto-art.
- Personal Ornaments: The production of personal ornaments, such as shell beads, in connection with complex social behaviors. Often found in burial sites, these artifacts indicate a growing emphasis on symbolic communication and codified ritualism.
- Early Evidence of Burial Practices: Almost immediately following Tobo's eruption, burial practices became significantly more prevalent, implying the sudden development of concepts related to mortality, spirituality, reality, and the afterlife.
- ↑ The density of such objects have led to the Lesotho area becoming the assumed general locale of the surviving human populations
