Abstract
Genome data have revealed great variation in the numbers of genes in different organisms, which indicates that there is a fundamental process of genome evolution: the origin of new genes. However, there has been little opportunity to explore how genes with new functions originate and evolve. The study of ancient genes has highlighted the antiquity and general importance of some mechanisms of gene origination, and recent observations of young genes at early stages in their evolution have unveiled unexpected molecular and evolutionary processes.

Sequence and comparative analysis of the chicken genome provide unique perspectives on vertebrate evolution

LaDeana W. Hillier, +174 more
- 09 Dec 2004 - 
TL;DR: A draft genome sequence of the red jungle fowl, Gallus gallus, provides a new perspective on vertebrate genome evolution, while also improving the annotation of mammalian genomes.

The evolution of gene duplications: classifying and distinguishing between models.

TL;DR: A comprehensive classification of the models that are relevant to all stages of the evolution of gene duplications is presented, each of which predicts a unique combination of evolutionary dynamics and functional properties.

DNA Transposons and the Evolution of Eukaryotic Genomes

TL;DR: This review focuses on DNA-mediated or class 2 transposons and emphasizes how this class of elements is distinguished from other types of mobile elements in terms of their structure, amplification dynamics, and genomic effect.
Journal ArticleDOI

The locus of evolution: evo devo and the genetics of adaptation

TL;DR: There is no theoretical or empirical basis for the evo devo contention that adaptations involving morphology evolve by genetic mechanisms different from those involving physiology and other traits, and substantial data on the genetic basis of adaptation from both genome-wide surveys and single-locus studies are examined.

The Neutral Theory of Molecular Evolution

Motoo Kimura
TL;DR: The neutral theory as discussed by the authors states that the great majority of evolutionary changes at the molecular level are caused not by Darwinian selection but by random drift of selectively neutral mutants, which has caused controversy ever since.
