What is a body part in humans that regenerates if removed?
Why does it regenerate?
A salamander can regrow its tail if it is removed.
The sea star (also called the “star fish”) can regenerate its legs if removed.
You also have a body part that can regenerate!
If a surgeon removes one of your lower rib bones, it will regenerate itself.
One surgical procedure is called a “Split-rib cranioplasty”. Doctors have reconstructed the skulls of injured patients using donated rib bone. “All patients had complete regeneration of the donor rib”!

Another surgical procedure that uses the rib bones is called “thoracoplasty”. This surgery is useful in scoliosis patients that have defective ribs. “Amazingly, ribs grow back and, when they do, they will grow back straight.”
Why do salamanders regenerate?
Some salamander species use tail autotomy to escape predators. The tail will drop off and wriggle around for a little while, and the salamanders will either run away or stay still enough to not be noticed while the predator is distracted. Salamanders routinely regenerate complex tissues. Within only a few weeks of losing a piece of limb, a salamander perfectly reforms the missing structure.
This is a useful trait for the salamander.
Why did people evolve(?) or be designed(?) to regenerate ribs?
Long before modern medicine, internet and video, radio, and electronics… long before modern technology…
A text was written that explained how a regenerating rib could be useful.
(~ 1,450 BC)
Around 3,460 years ago these words were inscribed by a man named Moses, to describe how the first woman was created.
God caused the man to fall into a deep sleep; and while he was sleeping, he took one of the man’s ribs and then closed up the place with flesh. Then the LORD God made a woman from the rib he had taken out of the man, and he brought her to the man.
The man said,
“This is now bone of my bones
and flesh of my flesh;
she shall be called ‘woman,’
for she was taken out of man.”
That is why a man leaves his father and mother and is united to his wife, and they become one flesh.
Science today confirms that when a rib is removed from a human, it regrows. In fact, if a rib is removed, it will regrow completely in about 6 months. Men and women both have the same number of ribs. We each have 12 pairs of ribs.
If God designed our ribs to regrow, it helps explain why both men and women have the same number of ribs. If a rib was removed from the first man to make the first woman, the rib probably grew back, so he would be fully man again.
Why Do People Regenerate Ribs?
But why would humans have “evolved” or be “designed” to have regenerating ribs, but yet most of our other bones do not? It is specifically the rib bones, not arm bones or leg bones, that regenerate. Why? The best logical explanation is that the book of Genesis, written thousands of years ago, is an accurate record of how people were created: by God. And specifically, God took a rib from man to make the first woman. So that the first man would not be incomplete, his rib grew back.
If God made woman from man, why would God make her from a bone in man’s side?
Woman was not made from man’s head to rule over him.
Woman was not made from man’s feet to be trampled upon.
If God made woman from man’s side, maybe it was because man should keep her near his side to be his companion and near his heart to be loved.
