How did eukaryotic cells evolve, and why was this advance so important in life history? What will be an ideal response?
Eukaryotic cells have a cell nucleus, more advanced internal structures, and mostly reproduce sexually.
By the Mesoproterozoic, or even as early as 1.4 billion years ago, two or more prokaryotic cells
entered into a symbiotic relationship and eventually could only exist as a whole. The evolution of
eukaryotic cells allowed the evolution of multicelled organisms
