If the creator is a creative intelligence, then we should expect similarities and differences within each organism. There are no limitations to .What relationships between genomes of organisms would we *not* expect to see if they were created by a creator and not through an evolutionary process? And why, given some characteristics of that creator?
Where is this genetic information coming from to be passed on to future generations?Not intelligent at all. The more grandchildren you have the more copies of your genes (and the mutations they carry) are passed on to future generations.
After that beneficial mutations increase like compound interest. The more copies there are in the population today, the more copies there will be in future generations.
