Cambrian Explosion
Save
The Cambrian Explosion is a term used to describe the sudden appearance of a wide variety of complex life forms in the fossil record about 541 million years ago, during the Cambrian period of the Paleozoic era. This event marked a major turning point in the history of life on Earth, as it saw the emergence of most of the major animal groups that exist today.
What Caused the Cambrian Explosion?
The exact cause of the Cambrian Explosion is still debated among scientists, but there are a number of hypotheses that have been proposed. One popular hypothesis is that the rise of oxygen levels in the atmosphere and oceans during the late Precambrian period created a more favorable environment for complex life forms to evolve.
Another hypothesis is that the Cambrian Explosion was triggered by a series of environmental changes, such as the breakup of the supercontinent Rodinia and the formation of new ocean basins. These changes may have created new niches for organisms to evolve into, leading to the rapid diversification of life forms.

The Impact of the Cambrian Explosion
The Cambrian Explosion had a profound impact on the history of life on Earth. It marked the beginning of the Phanerozoic eon, which is characterized by the presence of abundant and diverse animal life. The Cambrian Explosion also led to the evolution of many of the major ecosystems that exist today.
Studying the Cambrian Explosion
Scientists study the Cambrian Explosion by examining fossils from the Cambrian period. These fossils provide a wealth of information about the morphology, behavior, and ecology of the animals that lived during this time. By studying these fossils, scientists can learn more about the causes and consequences of the Cambrian Explosion.
Careers in Cambrian Explosion Research
There are a number of different careers that involve studying the Cambrian Explosion. These include:
- Paleontologist: Paleontologists study fossils to learn about the history of life on Earth. They may specialize in studying the Cambrian period or the Cambrian Explosion.
- Geologist: Geologists study the Earth's history and structure. They may specialize in studying the Cambrian period or the environmental changes that occurred during this time.
- Biologist: Biologists study living organisms. They may specialize in studying the evolution of animals or the ecology of the Cambrian period.
