Abstract
Rapid divergence of gene copies after duplication is thought to determine the fate of the copies and evolution of novel protein functions. However, data on howlong the gene copies continue to experience an elevated rate of evolution remain scarce. Standard theory of gene duplications based on some level of genetic redundancy of gene copies predicts that the period of accelerated evolutionmust end relatively quickly. Using a maximum-likelihood approach we estimate preduplication, initial postduplication, and recent postduplication rates of evolution that occurred in themammalian lineage.Wefind that both gene copies experience a similar in magnitude acceleration in their rate of evolution. The copy located in the original genomic position typically returns to the preduplication rates of evolution in a short period of time. The burst of faster evolution of the copy that is located in a new genomic position typically lasts longer. Furthermore, the fast-evolving copies on average continue to evolve faster than the preduplication rates far longer than predicted by standard theory of gene duplications.We hypothesize that the prolonged elevated rates of evolution are determined by functional properties that were acquired during, or soon after, the gene duplication event.
