Identifying the earliest animal on Earth has been a long-standing scientific question. Research on Dickinsonia costata, an organism that lived approximately 558 million years ago, has provided evidence relevant to this question. The earliest traces of animals […]
For approximately four billion years, life on Earth consisted of single-celled organisms. Around 575 million years ago, multicellular organisms appeared and began to diversify. The causes of this event, known as the Avalon explosion, remain uncertain. This […]
A microscopic fossil discovered in China was initially interpreted as a possible early relative of humans. The aquatic animal resembled a rounded sac covered by a thin outer layer. Understanding the evolutionary origins of humans remains a recurring scientific question. […]
British researchers reported fossil structures interpreted as microorganisms that may be 3.77–4.29 billion years old. If confirmed, they would represent the oldest known evidence of life on Earth, according to Agerpres. These microfossils were found in quartz-rich rocks at Nuvvuagittuq, north-east […]
