A simple experiment shows how simple organic molecules could be concentrated enough to form lipid bilayers similar to those that make the membranes surrounding our cells. This is a practical model of how protocells could have formed in the chemical march from non-life to life.
As Oldcola writes, it’s simple, elegant, and effective.
