How we came to be: Scientists get first look at the evolution of early complex animals - AP News

Scientists have gained new insights into how early complex animals evolved, marking a significant advance in understanding the origins of life's diversity. The research provides the first detailed look at the evolutionary processes that transformed simple organisms into the varied animal forms we see today. This discovery helps fill a critical gap in the fossil record and evolutionary timeline, offering clearer evidence of how multicellular life developed from its earliest stages. The findings draw on modern genetic analysis and fossil evidence to trace these evolutionary pathways. Understanding these mechanisms is fundamental to comprehending how Earth's biological complexity emerged over millions of years.
