What's the difference between permeation and pervasion?
Permeation
Definition:
(n.) The act of permeating, passing through, or spreading throughout, the pores or interstices of any substance.

Pervasion
Definition:
(n.) The act of pervading, passing, or spreading through the whole extent of a thing.
Example Sentences:
(1) Dictated by underlying physicochemical constraints, deceived at times by the lulling tones of the siren entropy, and constantly vulnerable to the vagaries of other more pervasive forms of biological networking and information transfer encoded in the genes of virus and invading microorganisms, protein biorecognition in higher life forms, and particularly in mammals, represents the finely tuned molecular avenues for the genome to transfer its information to the next generation.
