As long as I’m on the subject of overwhelming points of similarity vs. underwhelming points of difference, a few points of similarity between man and chimp in no particular order, off the top of my head:
ten fingernails on ten fingers
two opposable thumbs
two wrists
two elbows
hair
skin
two eyes
two ears
nose
mouth
teeth
throat
ribs
two lungs
skull
brain
neck
two shoulders
two nipples
four chamber heart
liver
two kidneys
stomach
esophagus
pancreas
bile duct
small intestine
large intestine
private parts
hips
knees
ankles
red blood cells
white blood cells
bone marrow
yada yada yada
I could go on for pages and pages…
If man and chimp didn’t both descend from the same ancestor then surely the designer worked off the same template because there’s no denying the vast majority of parts and assembly are the same. What exactly is the practical difference between common descent and common design when the result is the same – so many undeniable points of similarity that there’s no question of a close relationship of some sort?
