At least, some of your genes come from viruses that slipped their DNA into the genes of our primate ancestors millions of years ago.

Some might say that that 'slipping in' was the work of the Annunaki.
Isn'nt that an intresting theory.

The DNA remnants of these ancient "retroviruses," distant relatives of today's HIV, account for an estimated 8 percent of the human genetic code and may have enabled master genes that account for some of the differences between us and our chimpanzee relatives.

Not all <A href="http://www.livescience.com/health/060529_mm_genes.html">genes</A> are created equal; the master genes can turn the others on and off, thus gaining control over genes related to cell division, DNA repair and programmed cell death. (This regulation of genes allows for tighter control of gene expression (i.e. which genes are turned on or off), which can account for the wide differences between humans and other apes, despite our very similar genetic codes.)
