USE YOUR THINKERS!
One of the most questionable claims is that which comes from the book of Genesis in the Holy Bible concerning the origin of the female gender. The Bible statement is straightforward, God put the man, Adam,in a deep sleep and removed one of his ribs. He used that rib to fashion the woman, Eve (Genesis 2:21 & 22).
Endless assumption have been made by reading in personal interpretations of the text such as men in general have less ribs.
Let's ignore the fact that a lost body part is not hereditary. A parent with a missing arm or leg will no more past on that feature to their offspring, than one with an absent rib. Medical advancement has proven that the rib regenerates. Interesting enough, it's only possible when the periosteum remains intact. This brings us to Genesis 2:21,
"closed up the flesh at that spot" (where the rib was). Periosteum is a tissue/membrane (flesh) that coats the exterior of the majority of bones. Osteogenic cells (osteoblasts) within, functions in the reproduction of bones.
