Ancient 500-million-year-old fossil fills life’s missing chapter

The Mystery of the Furongian Gap Approximately 500 million years ago, a significant event in the history of life on Earth occurred. This period, known as the Cambrian, is marked by an explosion of biodiversity in the fossil record. However, there is a notable gap in this record referred to as the “Furongian gap.” This missing chapter has puzzled scientists for years, as it appears between two periods of rapid evolutionary development.

Ancient 500-million-year-old fossil fills life’s missing chapter. The Mystery of the Furongian Gap Approximately 500 million years ago, a significant event in the history of life on Earth occurred. This period, known as the Cambrian, is marked by an explosion of biodiversity in the fossil record. However, there is a notable gap in this record referred to as the “Furongian gap.” This missing chapter has puzzled scientists for years, as it appears between two periods of rapid evolutionary development. The Furongian gap is intriguing because it suggests a potential biological crisis. Some researchers believe that environmental instability, changes in ocean chemistry, cooling climates, and a lack of oxygen in ancient seas may have contributed to this decline. However, a new study published in the journal BMC Biology offers a different perspec...
