Human have a sort of glue that fills gaps. When exposed to air,  these cells latch on and harden. They don’t know what the original blueprint entails because they’re just floating about in the bloodstream. When they get to a hole, they don’t know where the original plan was or what they should look like. 

It’s actually a human superpower. Other animals just die.
