The world’s remote algae fossils date back to billions of years as per the latest investigation by earth scientists at McGill University. Depended on this discovery, the researchers also reckoned that the foundation for photosynthesis in today’s plants existed 1.25 million years before.

This study appeared in journal Geology and could decipher a well-established enigma about the age of the fossilized algae that were primarily found in rocks of Arctic Canada in 1990. The microscopic organism is assumed to be the dilapidated unmediated predecessor of modern plants and animals, but its age was appallingly dated with approximations setting it somewhere between 720 million and 1.2 billion years.

The recent research also append to contemporary proof that interim of earth’s history usually mentioned to as a Boring Billion may not have been so boring, after all. From 1.8 to 0.8 billion years ago, archaea, bacteria and a sprinkle of intricate organisms that was defunct and pound about the planet’s oceans with meager or environmental alteration to show for it. In actuality that era may have prepared for the escalation for more intricate life forms that reached the finale 541 million years ago with the so-called Cambrian Explosion.

McGill PhD student Timothy Gibson, lead author of the new study said that the proof is started to structure that Earth’s biosphere and its environment in the later fraction of the ‘Boring Billion’ may literally have been more spirited than formerly contemplated.

To determine the fossil’s duration, the researcher flung a camp in a rocky domain of remote Baffin Island, where Bangiomorpha pubescens fossils have been discovered in defiance of the intermittent August blizzard and tent subsided winds, they accumulated specimens of black shale from rock layers that intermediated the rock unit involving fossils of the alga. Utilizing the Rhenium-Osmium (or Re-Os) dating technique petitioned progressively to sedimentary rocks in contemporary years, they decided that the rocks were 1.047 billion years old.
