Further evidence for common descent comes from genetic detritus such as pseudogenes, regions of DNA which are orthologous to a gene in a related organism, but are no longer active and appear to be undergoing a steady process of degeneration.
The claim that evolution results in moral progress is not part of modern evolutionary theory – that claim is associated with Social Darwinism, which held that the subjugation of the poor, and of minority groups, was favored by evolution.

 Pharyngula::Evolution of the X chromosome   (Site not responding. Last check: 2007-10-19)
The evolution of recombination suppressors is not at all difficult—a simple inversion on one chromosome can do it—so this is not a difficult thing for evolutionary processes to do.
Unlike the autosomes, the X chromosome is therefore resistant to these kinds of juggling of fragments, and so tends to preserve its original complement of genes.
There is evidence for this from both comparisons of distantly related species (Carvalho & Clark 2005) and closely related species (Bachtrog & Charlesworth 2002).
