And the rib, which the LORD God had taken from man, made he a woman...
Genesis 2:22
"....why men don’t have one fewer rib than women if God made Eve from Adam’s side (or rib).
The way I answer this is: If a man had an accident and his leg was amputated as a result, and then he married and had children, would all his children have only one leg?
When God took part of Adam to make Eve, he didn’t change Adam’s genes.
Of course not! This is because the instructions for how we are constructed are contained in the DNA in the nucleus of our cells—in our genes.
When God took part of Adam to make Eve, he didn’t change Adam’s
genes. All the information in Adam’s genes was still there. And of all
the bones in the human body, the ribs are the only ones that can regenerate
(grow back) if the sheath of tissue (periosteum) is left when the bone
is removed. So Adam may not even have had one fewer rib than Eve for
very long." AIG
