I set out to review the evolution of eukaryotic intracellular traffic, but along the way a new hypothesis came into focus: maybe the earliest membrane carriers were tubules, not coated vesicles!

New preprint: ecoevorxiv.org/repository/v...

Here’s the idea. 🧵
A schematic showing two models for the evolution of the eukaryotic cell plan starting from an archaeal ancestor. The "inside-out" and "outside-in" models both lead to an intermediate stage with internal and plasma membranes connected by tubules. The sequence continues through the formation of an endomembrane lumen, followed by the emergence of membrane contact sites and tubular carriers, and finally coated vesicles and stable compartments.
