Modern Science Doesn’t Call the Appendix Purely Useless

In real-world biology, it wouldn’t have been a good idea for Echel to remove the unborn baby’s appendix just because he thought it was “useless.” Here’s why:

📌 Modern Science Doesn’t Call the Appendix Purely Useless

It used to be widely taught that the appendix was a vestigial organ with no real purpose — basically leftover anatomy with no function. But current research shows that isn’t the whole story.

🧠 What the Appendix Does (According to Biology)

1. Supports gut bacteria and microbiome balance

The appendix appears to act as a “safe house” for beneficial gut bacteria — a reservoir that can help repopulate the intestines with good microbes after illness or antibiotic use.

2. Plays a role in the immune system

It contains lymphoid tissue (immune cells) that assist in immune responses — especially in young people as their immune systems develop.

So while it isn’t essential for survival and humans can live without it (which is why people get appendectomies), it does serve useful roles in immune support and maintaining gut health.

🧒 For a Baby, Its Role Could Be Even More Significant

In infants and young children, the immune and microbiome functions of the appendix are particularly relevant. Removing it without cause (especially before birth) could in theory reduce that support — even if a person can survive without one later.

🧩 Why This Matters for The Story

So in the context of your narrative:

• Yes, Echel’s decision was reckless and poorly informed, because he acted without understanding the actual evolving science about the appendix.

• It makes sense that a higher being (God) would be protective, given that the appendix does have beneficial roles, even if humans historically misunderstood it.
