We lovers of microbes delight in the complexity of multicellular bacteria such as the actinomycetes, the myxobacteria, and some cyanobacteria. But, how often do we stop and think about how eukaryotes became multicellular and how the likes of us came about? To remedy this state of affairs, we suggest a very fine review on the origin of multicellularity...

Organelles were endosymbionts that either made good or were enslaved, depending on your point of view. Either way, some of their genes now reside in the nuclear genome of their eukaryote host. We also know that there are some bacterial endosymbionts living today within multicellular eukaryotes. Can their genes also...
