The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Mutations in smooth muscle α-actin (ACTA2) lead to thoracic aortic aneurysms and dissections (2007, background): “Novel genes often arise from rearrangements, truncations and fusions of existing gene”
THE LOCUS OF EVOLUTION: EVO DEVO AND THE GENETICS OF ADAPTATION (2007, background): “In a review on the origin of new genes, Long et al. (2003) describes these and many other processes.”
The evolutionary origin of orphan genes (2011, background): “Orphan genes are thought to be particularly important for taxon-specific developmental adaptations and interactions with the environmen”
DNA transposons and the evolution of eukaryotic genomes. (2007, background): “One of the most direct contributions of TEs to host genome evolution is as a source of raw material that can be used for the assembly of new genes and functions (12, 16, 101, 102, 125, 186).”
The evolution of gene duplications: classifying and distinguishing between models (2010, background): “, or a retrotransposed copy may recruit regulatory elements in the new location or be integrated into an existing gene, which results in the formation of a chimeric gen”
Origins, evolution, and phenotypic impact of new genes. (2010, positive): “In agreement with this notion, a number of chimeric genes with important functions have been described (Long et al. 2003; Zhou and Wang 2008; Kaessmann et al. 2009).”
