The origin of multicellularity refers to the evolutionary process through which organisms transitioned from unicellular forms to complex multicellular structures. This pivotal event in biological history led to the emergence of diverse life forms and ecosystems, allowing for specialization of cells and the development of more complex organisms. The study of Precambrian fossils provides critical insights into this transition, revealing the early evidence of multicellular life and its evolutionary significance.
