Why do humans exist? A major part of the answer: because Pikaia Gracilens survived the Burgess decimation.

Summary

This quote implies that one of the main reasons for human existence is the survival of Pikaia Gracilens during the Burgess decimation. The reference to Pikaia Gracilens, an ancient worm-like creature, suggests that its survival was a significant event in the evolutionary history of life on Earth. It highlights the idea that the chain of existence leading up to humans originated from the persistence of certain organisms in the face of cataclysmic events. Hence, the quote suggests that our existence can be attributed, at least partially, to the fortunate survival of certain species throughout Earth's history.
