WHAT ARE YOU MADE OF?

Scientists in Cambridge have made an important discovery.  Not all genes are passed on from your ancestors.  145 of them come from somewhere else.  The said scientists are of the opinion that micro-organisms have somehow boarded the human genome.  Supposing, though, they are something else?   I gather the micro-organism explanation remains an hypothesis.  Supposing they are the genes of unutterably horrible tentacled beings from the bottom of the sea that have somehow intermingled with ours?  That would explain a great deal about the physical characteristics of my wife's aunt.  There are 145 of these genes that are non-ancestral.  It is possible they are still entering our genetic makeup.  Keep all your orifices well fortified!
