My question was more around question 4 in the OP rather than question 1. Is it true that human DNA can only encode "a few billion" bits, and is that enough to build a human, or are there information-creating processes needed to finish the "programming"? Our brains are trained by experience to build certain connections, so is the information to build the connections all that counts, or is the information in the connections themselves also important? I heard that as what you were saying, but I wanted to clarify the importance of that.
