I can only assume you linked to the wrong study because the one in your post only talks about pleiotropy and general on/off-switches and throws in its evolutionary benefits.
This will be the last time I post in response to the goals of evolution so I'm sorry of this is controversial but...
"Reverting back to original form"
That's just...not correct. Alas, if you want a debate on the mechanisms of biology then it's not for here. Again, I only mentioned it to strip down attraction to the basics. I'll gladly post in another thread if you want to make one.
