Mechanistics of the endosymbiotic theory I: Figures

In this post I collect images that show a mechanistic scenario for the inclusion of a free-living bacterium into another cell. It is not known what the host looked like, whether it was a primitive eukaryotic cell or another prokaryote. Consensus is the latter, although it doesn’t make a real difference for the scenenario. My personal opinion about the pictures of primitive cells caught in the act of swallowing another cell, is that it shows a lack of insight in the basics and complexity of evolutionary processes. Here as well, judge for yourselves.
