The Bare Bone Facts
Wouldn’t bones made of hardened wood or even iron be better than what God has given us? Find out on today’s Creation Moments Minute.
Some materials, like cast iron and concrete, are very good at withstanding compression forces but very poor in handling stretching forces. Using one of these materials to build a structure that undergoes tensile or stretching forces could lead to disaster.
It’s a good thing, then, that normal bone is three times as strong as good solid wood and nearly as strong as iron! Tests have shown that the tensile strength of bone is 35,000 pounds per square inch, while iron is 40,000 pounds per square inch. But bone material is far better than iron because it is three times lighter and much more flexible.
No bones about it – the structure of your bones is too carefully engineered to have been an accidental product of mindless evolution.
