Résuméduprojet:
Heredity — the fact that offspring resemble their parents — is taken for granted, but heredity is a
derived trait and requires an evolutionary explanation. In its most basic manifestation, heredity is
nothing more than interactions between particles that ensure that information contained in one
particleisalwayspackagedwithinformationcontainedwithinaparticleofanotherofadifferent.Our
ideaisthatheredityemergedalongwiththefirstcollectives(ofparticles)andisadirectconsequence
of selection on collectives, which in turn depends on specific ecological conditions. We propose to
test this idea by real-time evolution experiments using bacteria maintained in thousands of tiny
droplets. We also propose to develop new mathematical models to guide our investigations. The
project is interdisciplinary and takes advantage of the unique opportunities provided by PSL for
