From Cells to Complexity: The Evolutionary Leap to Multicellularity explores one of the most pivotal transitions in the history of life on Earth—the emergence of multicellular organisms. For billions of years, life existed only as single-celled organisms until, around 800 million years ago, cells began to form stable groups. This video explains how specific traits—cell adhesion, intercellular communication, and cell specialization—evolved to enable complex organisms like plants, animals, and humans to form and  thrive. To bring this project to life, I used several creative tools: I created the narration and animated scenes using Fliki, designed scientific illustrations in BioRender, and used Canva for layout and scene transitions. The full script and structure were developed and refined using ChatGPT, which helped transform complex biological concepts into a clear and engaging story.
