Description

In the fifties, Oparin imagined liquidlike compartments called
coacervates, which could have played a central role in the origin of life [1].
Although the experimental verification of this idea remained scarce for many
years, the idea resurfaced recently in various systems of biological interest
in which liquid non-membrane compartments were found. An important aspect
not tested in the Oparin scenario is the role of the transient nature of
compartmentalization. Here, we discuss a general class of multilevel selection
with transient compartmentalization [2], and its robustness against noise
and mutations [3].
