What about those jumping genes?

I had an argument with crashfrog about jumping genes way back when (I can't find the thread.) It involved the discovery of tse-tse fly genes creeping around in the human genome. Well, this news from Nature is interesting and relevant to that issue. Here's a case of a fly getting its version of what happened to a human in the movie The Fly: Bacterial genome found within a fly's
DNA transfer from bacteria to animals is more common than thought.So maybe this supports the findings of insect genes in the human genome.The topical question for this proposed thead is: Do you think jumping genes could have played a significant role in the course of either biological or social evolution?”HM
