Reconstruction of ancestral genomes uncovers unexpected genome dynamics in major evolutionary transitions


The history of life on Earth contains major evolutionary transitions, the emergence of new features that dramatically changed the biology of organisms and the planet. Understanding the genomic basis of these events, such as the origin of animals or plants, is one of the major challenges of modern evolutionary biology. Using extensive genome comparisons, we infer the gene complement of the genomes of the ancestors of major groups or organisms (animals, plants, etc.). These analyses uncover an unprecedented increase in the extent of genomic novelty during the origin of metazoans and embryophytes, and identify new core genes essential to their biology. We also show how gene loss has shaped the genomes of animals after their emergence. Together, these results shed new light on the role that the dynamic nature of genomes played during these transitions.
