The last cradle of life

The last cradle of life



Souce


What was the place on Earth where organic molecules and other elements that perhaps we still need to discover were united to give rise to life, what was that cradle of life like, on December 6, the University of Colorado Boulder published a work by geologist Brian Hinek.


This work reveals to us what may be one of the last cradles of life that still remain on Earth, it is located in Puna AtaCama in Argentina, it seems like a place on an extraterrestrial planet and the fact is that the Earth in its beginnings would have seemed like a planet to us. completely extraterrestrial because at that time, 3.5 billion years ago, it was something similar to the images shown, although with the difference that if we traveled in time we would need a mask to breathe, since at that time there was very little oxygen and a lot of CO2.




This lost lagoon is located 9 hours walk from the nearest village, at 3600 m altitude in one of the driest and most forgotten places on the planet where rain is a very strange phenomenon, the sun mercilessly hits any living being that tries to arrive at the place and yet there is life there, there are enormous constructions of stromatolites or complex microbial communities.


These communities form giant mounds of rock as they grow very slowly. These stromatolites can be found in other places on earth, but these ones in Argentina are enormous and look much more like those from billions of years ago that could reach up to 6 m high.

This place offers scientists a natural laboratory to understand how life emerged on Earth and perhaps also on other planets such as Mars, since the red planet had the same environmental conditions as Earth billions of years ago, if life emerged there would initially look like what we are seeing in this Lagoon in Argentina, but scientists have little time to gather data because apparently this cradle of life could be destroyed in a few years, since there is a company that has leased the area to extract lithium.


Researchers said they hope to protect some of these unique sites, these cradles of life, or at least detail what's there before it disappears forever.
