Here’s a link to a PhysOrg.com article talking about ERV’s (“jumping genes” per Barbara McClintock) and the newly discoverd role they seem to have played in primate evolution. Here’s a quote from the link: “Now it appears that another level of evolution occurs that is not driven by point mutations. Instead, retroviruses insert DNA sequences and rearrange the genome, which leads to changes in gene regulation and expression.”
Excuse me if I’m wrong, but this, it seems to me, is the kind of thing that would be helpful to discuss here at UD.
