Nuclear receptors are a very good model to investigate the dating and functional role of these duplications, since they are dispersed in the genome, allow robust phylogenetic reconstruction, and are functionnaly well characterized, with different adaptations for different para

One of two major routes of gene amplification, retroposition, originated from mechanisms that facilitated the transition to DNA as hereditary material. Even in modern genomes the process of retroposition leads to genetic novelties including the duplicati

Possible molecular evolutionary mechanisms that underlie this increase in complexity fall into a small number of categories, one of which is gene duplication and subsequent structural or regulator

The presence of several groups of paralogous chromosomal regions in the human genome is a reflection of this increase. The simplest explanation for the existence
