TLDR
A better understanding of these patterns should provide valuable information on the evolution of genes located on the X chromosome and suggest solutions to more general problems in molecular evolution, such as detecting selection and estimating mutational effects on fitness.
Abstract
Although the X chromosome is usually similar to the autosomes in size and cytogenetic appearance, theoretical models predict that its hemizygosity in males may cause unusual patterns of evolution. The sequencing of several genomes has indeed revealed differences between the X chromosome and the autosomes in the rates of gene divergence, patterns of gene expression and rates of gene movement between chromosomes. A better understanding of these patterns should provide valuable information on the evolution of genes located on the X chromosome. It could also suggest solutions to more general problems in molecular evolution, such as detecting selection and estimating mutational effects on fitness.

Intralocus sexual conflict.

TL;DR: Outstanding questions about the causes and consequences of intralocus sexual conflict at the genomic level are highlighted, and a broader appraisal that also takes account of its potential to drive adaptive evolution and speciation is urged.

Insights into hominid evolution from the gorilla genome sequence

Aylwyn Scally, +74 more
- 08 Mar 2012 - 
TL;DR: A comparison of protein coding genes reveals approximately 500 genes showing accelerated evolution on each of the gorilla, human and chimpanzee lineages, and evidence for parallel acceleration, particularly of genes involved in hearing.

A Mathematical Theory of Natural and Artificial Selection, Part V: Selection and Mutation

TL;DR: This work shall first consider initial conditions, when only a few of the new type exist as the result of a single mutation; and then the course of events in a population where the new factor is present in such numbers as to be in no danger of extinction by mere bad luck.
