What is the Difference Between Ediacaran Extinction and Cambrian Explosion?
🆚 Go to Comparative Table 🆚The Ediacaran Extinction and Cambrian Explosion are two significant events in the history of life on Earth. The main differences between them are:
- Type of event: Ediacaran Extinction refers to the mass extinction of macroscopic animals that occurred at the end of the Ediacaran period. In contrast, the Cambrian Explosion is the sudden appearance of mineralized skeletons and complex trace fossils, marking a rapid diversification of life.
- Timing: The Ediacaran Extinction occurred 542 million years ago, while the Cambrian Explosion occurred 541 million years ago. Notably, the major event of the Cambrian Explosion is the sudden appearance of mineralized skeletons and complex trace fossils.
- Causes: The Ediacaran Extinction is believed to have been caused by environmental perturbations and perturbations across the Earth. By contrast, the Cambrian Explosion is thought to have been triggered by multiple factors, including changes in ocean chemistry, environmental conditions, and key genetic complexes.
- Impact on life: The Ediacaran Extinction led to the extinction of many macroscopic animals and organisms. The Cambrian Explosion, on the other hand, heralded the appearance of diverse macroscopic biomineralized fossils and complex trace fossils, marking a significant diversification of life on Earth.

Comparative Table: Ediacaran Extinction vs Cambrian Explosion
The Ediacaran Extinction and Cambrian Explosion are two significant events in the history of life on Earth. Here is a table comparing the key differences between these events:
Feature | Ediacaran Extinction | Cambrian Explosion |
---|---|---|
Timeframe | Occurred at the end of the Ediacaran period | Occurred after one million years of Ediacaran extinction, around 541 million years ago |
Cause | The exact cause is still unknown, but some evidence suggests that marine anoxia contributed to the decline and eventual extinction of early organisms | The event is believed to have been a rapid appearance of complex animals with mineralized skeletons and complex trace fossils |
Organisms | Ediacaran biota and calcifying macroscopic eukaryotic organisms | A wide variety of animals with diverse body plans |
Impact | Mass extinction | Major ecological transformation and new interactions between organisms |
Significance | One of the most important evolutionary events in the history of Earth | One of the most important evolutionary events in the history of Earth |
