At some point here, you are going to cross a bridge and arriving on the other side make a few realizations; one of which is going to be the 'folly' of thinking that 'man' is composed of matter so radically different than that of animals and the other is that man was at some point bestowed with a spirit and a free will that sets him apart from other life on earth and in rendered him created in the image and likeness of the Almighty God...
Until then, we can expect to see more defense of that which defies logic and opposes *real* science; to those ends you will eventually be forced, just as those who thought the earth to be the center of the universe with the sun revolving around it, to 'invent' ever more bizarre beliefs, theories et al that aren't borne out in reality nor can stand the ultimate of all tests in this area: the continued unraveling and discoveries in and about the genetic code which is nature's "build print" or blue print if you will.
Funny stuff :-)
