It also clearly cites it at the bottom. Its not like this is plagiarism. Its clearly making the point that this is the new, awful truth of the world before us, and maybe we need a few avengers, like little Billy Ignore Instructions and his vindictive mom.

Thank you for the clarification! I was wondering if you meant literal shrinking, like telomeres, but over generations. I retract my former complaint!

To call the natural process of mutation, literally one of the requirements for any genetic evolutionary progress, “deteriorating” is, at best, short sighted. Most mutations do nothing, most of the ones that do something don’t occur in the one sperm that makes it into the ovum, and most of those that do something and make it into the ovum cause an early termination before birth. Some of those that get through all of these hurdles are the ones that cause random genetic variation and increased diversity, without which we actually DO get things like Hemophilia or other sex-linked issues going rampant in any given gene pool. Evolution takes a LONG time to work, but it requires wet and moldable clay to sculpt.
