DNA encoding can be altered under certain environmental conditions. This doesn't necessarily compromise the replication and propagation of the DNA.
In some cases though, it may.
Not all influences causing alteration to DNA, necessarily result in non-propagation.
These environmental changes may not be random, also.
Introducing non-randomness in this area results in a non-random process.

Not intentional, (unless human researchers haven't deliberately induced the changes).

Yep. I agree.
