I know enough to know that there are so many undiscovered backup systems in dna.
I once ran a computersimulation to see if I could calculate how much % of junk-dna was possible, and I got rather low numbers, so I usually figure our own dna has low amount's of junk as well. The way the dna folds affect the Whole system, which hint at quantummechanical links, and some really pro people once built an ai by evolution and chips. At one stage of their experiment they lacked ressourcess, so they decided to remove all chips not in contact with any current/electricity to use in some of the other ai's. The result was that the ai's with removed chips suddenly got altered behaviour which hinted that the very presence of the microchips had influence on the whole system. I'm not a scientist on the area of epigenetics, but I do know some related stories like the sex of crocodiles is determined by the temperature in the egg-nest, I think it was korea that discovered humans have temperaturebased epigenetics as well, infants exposed to cold grow up to be coldresistant and the same goes with heat. The stresslevel in women alters the dna of their baby in several area's one is becomming overweight. As men grows older their sperm becomes more mutated. Stuff like that. I also knows a little about horisontal vs vertical evolution.
