STATES CHRONICLE – The evolution of our planet was a mystery for us, for a long time. However, scientists never stopped looking for answers. Regarding this matter, a new discovery has been made! It seems like the first mass extinction on Earth was caused by biological engineers. Let’s find out more about them and how this extinction was possible.
When it comes to the term of mass extinction, people think of it as an apocalypse. But it doesn’t imply asteroids or erupting volcanoes in all occasions. Having that in mind, it seems like a new discovery was made regarding the first mass extinction on Earth. Simon Darroch, a professor which studies the environment and how it has evolved, discovered some fossils from more them 500 million years ago!
Those fossilized organisms existed in a world where the ecological transition was really fast and the animal life was more diversified than we can imagine, named the Cambrian explosion. When life first appeared on our planet, single-celled microbes dominated our planet for more than three billion years! They were called Ediacarans and “rulled” our planet for a long time, until the multicellular organisms appeared and took over the planet. The fossils that were discovered are a proof of an unusual ecosystem as the Cambrians were becoming more powerful in their evolution while the last Edicarians were trying to survive.
This first mass extinction on our planet was the end of the Edicarian-era. This event led to the Cambrian explosion, a new step that brought us closer to what we are today. So, basically, a group of evolved organisms managed to erase the first microbes that lived on our planet. The fossils that were found represent a clash between the two periods. They are one of the few proofs that the Edicararans and the Cambrians lived together for a while.
If humanity can learn something from the first mass extinction, is that the evolution of some organisms can make a huge difference. Nowadays, we are the most powerful change-makers our ecosystem can have. We can help the planet survive, but we also can be its strongest enemy. It is our choice if you want to build something to last for the future generations and for all the beings that live on Earth.
