The Toba Catastrophe also coincides with the disappearance of the Skhul and Qafzeh hominins. [98] Evidence from pollen analysis has suggested prolonged deforestation in South Asia, and some researchers have suggested that the Toba eruption may have forced humans to adopt new adaptive strategies, which may have permitted them to replace ...
The Toba eruption (the Toba event) occurred at what is now Lake Toba about 73,700±300 years ago. [15] It was the last in a series of at least four caldera-forming eruptions at this location, with the earlier known caldera having formed around 1.2 million years ago. [16]
Eruptions the size of that at Lake Toba 74,000 years ago, at least 2,800 cubic kilometres (670 cu mi), or the Yellowstone eruption 620,000 years ago, around 1,000 cubic kilometres (240 cu mi), occur worldwide every 50,000 to 100,000 years.
Year Disaster event Notes; disaster type, people killed, region affected, etc. 75,000–70,000 BP: Prolonged volcanic winter: Long lasting volcanic winters following the Toba catastrophe have been hypothesised to have killed every human not living in Africa at the time.
Under the Mitochondrial Eve article, Eve is believed to have lived about 150,000 years ago. That would predate the Toba catastrophe event by another 75,000 years. Whereas, in the case of Y-chromosomal Adam it is stated, he probably lived between 60,000 and 90,000 years ago. This time frame agrees more with the time of the Toba catastrophe.
The controversial Toba catastrophe theory, presented in the late 1990s to early 2000s, suggested that a bottleneck of the human population occurred approximately 75,000 years ago, proposing that the human population was reduced to perhaps 10,000–30,000 individuals [14] when the Toba supervolcano in Indonesia erupted and triggered a major ...
