Sexual reproduction, which created a wider variety of organisms Cell colonies, with organized special jobs and the introduction of the first ever multicellular organisms
During the late Precambrian, three major adaptations were significant: sexual reproduction, which increased genetic diversity; cell specialization that improved colony efficiency; and the evolution of multicellularity, which allowed for more complex organisms. These adaptations contributed to a great evolutionary leap, leading to the Cambrian explosion. Together, they marked a turning point in the development of life on Earth.
