The team, based in Gabon, claims to have found proof of 2.1 billion years ago’s animal life’s environmental circumstances hidden deep beneath rocks.
However, they contend that the organisms were confined to an inland sea, did not proliferate worldwide, and finally became extinct.
Not all scientists agree with the concepts, which represent a significant shift from mainstream wisdom.
The majority of scientists agree that animals first appeared 635 million years ago.
The findings contribute to the continuing discussion about whether or not the as-yet-unexplained formations discovered in Franceville, Gabon are made of fossils.
The scientists investigated the granite surrounding the structures.
Cardiff University’s Professor Ernest Chi Fru collaborated with a global group of scientists.
According to his theory, these organisms would have resembled slime mold, a single-celled, brainless organism that spreads via spores, he told News.
However, University College London Professor Graham Shields, who was not engaged in the study, admits he had some doubts.
He stated that further proof was required. “I’m not against the idea that there were higher nutrients 2.1 billion years ago, but I’m not convinced that this could lead to diversification to form complex life,” he added.
