Do men have less
ribs than women?
Question: Because God created Eve out of Adam, do men have less ribs than women?
Answer: The verses related to your question regarding ribs and whether the creation of women caused men to have one less than normal are in the book of Genesis.
. . . and while he was sleeping, he took out one of the man’s ribs and closed up the flesh. 22 He formed a woman out of the rib and brought her to him. (Genesis 2:21 - 22)
The direct answer to your question is that men do not have less ribs due to the creation of Eve. In regard to Adam, although the Bible is not specific, either he lived the rest of his life missing one of them or God healed him immediately after his 'surgery.'
Several Bible commentaries offer some fascinating thoughts to consider regarding God's creation of Adam and Eve. The Jamieson, Fausset and Brown Commentary states that Eve (representing all women) was not made from Adam's head in order to surpass him, or made from his feet so that she could be trampled on, but from his side so that she could be near and dear to his heart. Adam Clarke's Commentary says that some piece of Adam was needed to be used for Eve's creation, and that it was likely the flesh from his sides that were used (see Genesis 2:23). The commentary goes on to state that God could have formed Eve from the ground just like he did Adam, but had he done so she might have appeared to have no natural relationship to him.
The celebrated first century historian Josephus also weighed in regarding God's creation of humans. He said that it was only after God observed Adam wondering at the animals that were made male and female, and noticing he had no such companion, that he decided to create for him a mate out of his ribs.
