Genome evolution

Definition

Genome evolution is the process by which a genome changes in structure over time, through mutation, horizontal gene transfer, and sexual reproduction. The study of genome evolution involves multiple fields including structural analysis of the genome, genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics.

    Polyploidy occurs frequently but is usually detrimental to survival; thus, few polyploids survive in the long term. Here, evidence linking the short-term evolutionary success of polyploids to environmental upheaval is reviewed and possible longer-term evolutionary benefits of polyploidy are discussed.

    Multicellular organisms rely on a complex interplay between diverse cell types, but how multicellularity evolved from unicellular ancestors has long been a debated research question. In this Review, the authors describe how comparative and functional genomics have provided valuable insights into the transition between unicellularity and multicellularity, including how various molecular networks have been adopted for multicellular life.
