Scientists from The Australian National University (ANU) have succeeded in discovering the Protosterol Biota, which is referred to as the ‘lost world’ of ancient organisms. These microscopic creatures were found in ancient rocks in Australia that are billions of years old. The discovery is expected to change human understanding of their earliest ancestors.
Biota Protosterol itself is a microscopic creature that is part of a family of organisms called eukaryotes. They have a complex cell structure with mitochondria as the powerhouse of the cell and nucleus as the control and information center. The Protosterol Biota is believed to be our earliest known ancestor. Modern forms of eukaryotes that inhabit Earth today include fungi, plants, animals and single-celled organisms such as amoebas.
According to researchers, the LECA (Last Eukaryotic Common Ancestor) lived more than 1.2 billion years ago. Humans and all other nucleated creatures can trace their lineage back to LECA.
Researchers explain that these ancient creatures were abundant in marine ecosystems around the world and probably formed ecosystems for most of Earth’s history. The Protosterol Biota is believed to have lived at least a billion years before animals or plants appeared. Scientists have long searched for fossil evidence of these early eukaryotes, but their physical remains are extremely scarce. The 1.6 billion year old rock in Australia’s Northern Territory contains ancient chemical structures that hint at the presence of the Protosterol Biota.
One of the biggest puzzles of early evolution that scientists are trying to answer is “why did our highly capable eukaryotic ancestors not dominate the primordial waters of the world? Where are they hiding?” Professor Jochen Brocks from ANU examines rocks that are 1.6 billion years old and discovers Protosterol Biota.
Protosterol biota multiplied from about 1.6 billion years ago to about 800 million years ago. The end of this period in Earth’s evolutionary timeline is known as the “Tonian Transformation”, when organisms evolved. However, exactly when the Protosterol Biota became extinct is unknown.
The researchers used fossilized fat molecules to conduct research and discovered the Protosterol Biota. Without these molecules, we would never know that the Protosterol Biota existed. This discovery suggests that Earth’s ancient oceans may not have been composed of bacteria alone.
In conclusion, this research provides valuable information for humans about the origins of their ancestors and how ancient creatures have formed the ecosystems of most of the Earth. This research also uncovers the biggest early evolutionary puzzle in humans and tries to answer the question of why our eukaryotic ancestors did not dominate the world’s ancient waters.
