• Margulis hypothesised the popular classical theory for eukaryotic beginnings.
• Later, as an undergraduate, David Baum proposed the inside-out theory. This is where some eoctye, or archaea, lauched protruding blebs at epibiotic protobacteira. This is how the primitive cell would have harnessed another cell's prokaryotic metabolism for its own benefit, evolving into mitochondria, and in doing so, the inversion of cell membrane into two leaflets via engulfment generates the primitive nucleus -- two layers is still seen.
