Modular Assembly of Genes and the Evolution of New Functions
Abstract
Modular assembly of novel genes from existing genes has long been thought to be an important source of evolutionary novelty. Thanks to major advances in genomic studies it has now become clear that this mechanism contributed significantly to the evolution of novel biological functions in different evolutionary lineages. Analyses of completely sequenced bacterial, archaeal and eukaryotic genomes has revealed that modular assembly of novel constituents of various eukaryotic intracellular signalling pathways played a major role in the evolution of eukaryotes. Comparison of the genomes of single-celled eukaryotes, multicellular plants and animals has also shown that the evolution of multicellularity was accompanied by the assembly of numerous novel extracellular matrix proteins and extracellular signalling proteins that are absolutely essential for multicellularity. There is now strong evidence that exon-shuffling played a general role in the assembly of the modular proteins involved in extracellular communications of metazoa. Although some of these proteins seem to be shared by all major groups of metazoa, others are restricted to certain evolutionary lineages. The genomic features of the chordates appear to have favoured intronic recombination as evidenced by the fact that exon-shuffling continued to be a major source of evolutionary novelty during vertebrate evolution.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
