Superdense Biology:  One of the more intriguing Endowments that

Advanced Idea Mechanics postulates as Adamic is Invulnerability. 

Science tells us that there is a lot of “space” between our molecules.  

Needless space.  Why?  Our belief is that Adam, losing his prior estate,

became corrupt and lost Dominion.  Dominion is one of those unusual

Endowments that assured that Adam could not be overcome or injured

by any earthly agency.  Thorns, rocks, etc.—nothing could hurt him. 

This would imply that Adam had to be tougher, harder, and more resilient

than all of the things around him.  Superdensity would be the characteristic

that would allow this dominion.  If he was Superdense, he would be

invulnerable—and he would have to be, because diamond is pretty hard

(and there were probably diamonds, even in those days!).  We are

probably 94% less dense than we used to be! [work in progress]
