new study with a Canadian connection reveals that all human life on earth was obliterated two billion years ago.

Researchers came to this conclusion after testing barite, a mineral found in Belcher Islands, in the southeast part of Hudson Bay, which is part of Nunavut.

The rocks were helpful for researchers as they “lock in chemical signatures” needed to understand what the atmosphere was like when they first formed, co-lead author and Stanford University Ph.D. candidate Malcolm Hodgskiss told CNN.

Ultimately the study determined that there is such a thing as too much oxygen, by examining the circumstances surrounding the “Great Oxidation Event.”

Billions of years ago, long before dinosaurs, the only creatures that were able to survive on Earth were micro-organisms. When they photosynthesized, they changed the chemical composition of the air, leading to a surplus of oxygen that couldn’t be sustained.

The Earth’s atmosphere was ultimately sent askew, as the micro-organisms drained all the nutrients they needed in order to create oxygen. In turn, the biosphere – also known as life on Earth – experienced an “enormous drop,” and sci
