A 1.75 billion year old code cracks the origin of life on Earth

A 1.75 billion year old code cracks the origin of life on Earth. There has been a small lesson about photosynthesis that researchers are studying from 1.75 billion years ago, which is part of their quest to understand the origins of life.

The earliest known evidence of photosynthesis has been identified in microfossils found in north Australia’s desert by a team of academics, according to a recent study published in Nature. According to Popular Mechanics, this discovery could lead to a greater understanding of the origins of life.

According to researchers, these microfossils are the remains of an organismal class called cyanobacteria. These organisms could have existed for as long as 3.5 billion years, although the earliest fossil evidence dates back to approximately 2 billion years ago. 

Since, at some point in their evolution, some of these species developed thylakoids, which are structures within cells where photosynthesis occurs, they may have contributed tremendous amounts of oxygen to the atmosphere during the Great Oxidation Event due to the fact that they developed thylakoids, which are structures in cells where photosynthesis is taking place.

It is through these new findings that we have discovered the earliest evidence of photosynthesis that has been found to date. They say that the earliest photosynthesising cells appeared about 1.75 billion years ago, which extends the fossil record by at least 1.2 billion years. This finding confirms that photosynthesis started about 1.75 billion years ago.

As the authors stated in the paper, “[this discovery] allows for a new redox proxy to prob early Earth ecosystems and enables the unambiguous identification of early oxygenic photosynthesisers.” In this paper, they also note that the ultrastructure of fossil cells plays an important role in determining their paleobiology and early evolution.
