Toba catastrophe theory

The toba catastrophe theory is about a very big volcano that erupted a really long time ago. It was so big that it could be heard from thousands of miles away and it made a lot of ash and smoke go up in the air, so much that it almost covered the sun completely. This caused the whole planet to become colder and made a lot of plants and animals die.

Some scientists think that this event caused the population of humans to decrease a lot. There were only a few groups of humans left after this happened. They had to learn how to survive in a new and very cold environment. This event might have influenced how cultures and languages have developed over time.

Overall, the toba catastrophe theory is about a really big eruption that changed the world a lot, especially for early humans.
