cant confirm it cuz i don't know, but sounds like your onto something, man.

Utter nonsense.
First of all, there are lots...and lots...and lots of genes in the human genome. Scientists have barely skimmed the surface where studying them is concerned, much less trying to trace their heritage in a scientifically viable manner.
Secondly (and perhaps most importantly), going along that line of thought, *all* human genes cannot be traced back to be acquired from predecessors on the genomic evolutionary tree. That's the very nature of evolution; new genes come about through mutation. All of our genes are the result of that - they were all, at one time or another, mutations of some sort.
The statement that a specific 200 of them has such a quality is therefore meaningless.

Genes can enter our DNA through viruses. for example, out k-nine teeth are thought to introduced by a virus.
I wonder if that is the cause of disruptive evolution?
