Some 74,000 years ago, the Indian subcontinent was covered by ash. How? Mount Toba eruption in Sumatra. Apparently, Indians survived the massive explosion by the virtue of handmade tools. A new study has suggested how the tools helped them face the explosion and thrive for the next 50,000 years. Additionally, the hot magma is believed to have altered the topographical features by melting the rocky surfaces.
The explosion is a remarkable volcanic event since the last 2 million years. Chunks of ash and debris shrouded acres of earth causing temperatures to go topsy-turvy. Our ancestors were almost on the verge of extinction, so powerful was the force of Toba cataclysm. Human population witnessed a tremendous reduction in size as Toba exploded possibly leading to an ice age.
Homo sapiens are found to have developed social and economic strategies that enabled them to live and reproduce. Traces of the volcano are found in soil around Indian Ocean. The ash also provided ample evidence of the artefacts left by early humans—mostly includes tools, bones and other evidence of human occupation. Nonetheless, the entirety of survival story at the face of tremendous drop in temperature remains a mystery to be solved. The existence of humans in Asia earlier than calculated is also a novel discovery.
Effect of Toba Explosion of Global Climate
For decades, the explosion blocked out sunlight and heat, inducing a bone freezing temperature. Besides, acid rain showered as a by-product. In Greenland and Antarctica, samples of ash and acid of Toba is also found. Such was the mighty force of the phenomenon. The research study also proves that humans interbred with hominis species like Neanderthals, now archaic and extinct. Contradiction has surfaced as Chad Yost, a geoscientist at Arizona State University, Tempe, opines “The impact of the Toba eruption on climate has been overestimated.”
