Explore the mysterious origins of the cells all multicellular organisms are made from - eukaryotic cells - with Professor Lindsay Turnbull from the University of Oxford Everyone sometimes thinks they're special, but have you ever learned the truth of how special the cells in your body are? In this video we discover the 'ancient ones', a group of cells called the archaea, and the special role they play in the evolution of eukaryotes. Eukaryotic cells are generally large and full of internal structures, called organelles, one of which, the famous mitochondria, isn't quite what it seems. Finally, we look how slime moulds can gang up when conditions are right, giving us a glimpse of how true multicellularity evolved.
