Forging an evolutionary individual from separate replicators<\/strong><\/p>\n\n\n\n

Major evolutionary transitions occur when independently replicating particles unite into a higher-level individual. How selection comes to work on particle collectives and generates reliable heredity is unresolved. By packaging red and green plasmids in yeast cells we made plasmid communities units of selection: cell boundaries supplied discreteness, segregation generated variation, and cell division reproduced communities. Communities colouring cells yellow were preferentially propagated. Initially, yellow parents rarely produced yellow offspring, but continued selection aligned replicative fates of the two plasmids favouring recombinants that fused with the endogenous 2\u00b5 element. Chimera stability was secured by mutations in FLP1, which encodes a recombinase that otherwise resolves fused replicons. Reliable collective heredity, here a derived product of higher-level selection, marked completion of an evolutionary transition in individuality.<\/p>\n\n\n\n

About<\/strong> Paul B. Rainey:<\/strong> <\/p>\n\n\n\n

Paul was born in New Zealand and completed his bachelors, masters and PhD at the University of Canterbury. From 1989 until 2005 he was based in the UK where most of his time was as researcher and then professor at the University of Oxford. He began transitioning back to New Zealand in 2003, firstly as Chair of Ecology and Evolution at the University of Auckland, but then in 2007 moved to the New Zealand Institute for Advanced Study as one of its founding professors. Paul is currently Director of the Department of Microbial Population Biology at the Max Planck Institute for Evolutionary Biology in Pl\u00f6n (Germany) and Professor at ESPCI in Paris (France). He is a Fellow of the Royal Society of New Zealand, Member of EMBO and Member of the European Academy of Microbiology.<\/p>\n\n\n\n
