Well, all that has CHANGED recently! What a surprise! They have found JUNK DNA plays a VERY important role after all!
What very important role would that be? For an example, tell us what function the GLO or urate oxidase pseudogenes have in apes and people.
I'm aware of the Hirotsune, et al., paper in
Nature in 2003 that was the first-ever documentation of a "use" for a pseudogene. Do you have more recent information that shows "a VERY important role" for any others?
