Um...nope I did not.
According to Darwin this is a rank impossibility - the law of evolution is change according to a mix of random mutations and changing circumstances.
Its perhaps more helpful at least in layman's terms if you think of the gene as a line of code...the switches (in combination with a bunch of other things) that are active today make up what you are today...a great deal if not almost all of that old code is still there...it (depending upon what switches were on and off at the time) made up what your ancestors were in the past. With each and every exchange of dna that produces a new offspring tiny little sometimes imperceptible changes do take place (in some cases a variety of factors can cause rampant changes or even a switch being disconnected or miss-connected etc) but the overall line of code (including the old code) for the most part remains.
I assume (correct if wrong) that you mean the 'hard-wired' idea that genes in our brain are exactly the same as then, and that they are so detailed that they can decide our behaviour now, ( oh I didn't say they alone decide...the decision making process of a mind is complex...not so complex we don't know how it works mind you, just complex...and we have found that one's brain chemistry and overall physiological programing play a much larger part in the process than most people are comfortable discussing because they get overwhelmed and tend to think that science is telling us we are just like any machine etc and that our programing and built in responses largely guide our choices and that free will ...may just be illusion after all... its real enough tough...at least from our own perspectives) with these 'switches'. No one have been able to prove that such 'switches' excist, (um actually they did some time ago now...prove they exist...though not at all in the way your portraying them) they are just an idea - in the face of the many seriously working biologist who tear their hair and point out that genes can not express such detailed behaviour.
