For the wisdom of this world is foolishness with God...
1 Corinthians 3:19
"The evolutionists cited the persistence of the median artery in the forearm of some adult humans as evidence of visible evolution, but what are the facts? 
The median artery is temporarily found in the early human embryo where it supplies blood to the developing hand but usually degenerates long before birth. In the adult, blood is supplied to our hand by the radial and the ulnar arteries running in our forearm.
During the embryonic stage of our development, a third artery called the median artery (a branch from the ulnar artery) also supplies our hand.
The median artery usually regresses in the second month of fetal development but may persist after birth in about 8% of humans, where it is found in the forearm between the radial and ulnar arteries. The lack of the median artery is not known to result in any ill effects. In any event, the failure of the median artery to degenerate in a small percentage of humans tells us nothing about the evolution of the median artery."
