1% was an estimate suggested in 1975 which “came from crude comparisons of very limited stretches of human and chimp DNA that had been pre-selected for similarity.” “The human genome has about 3,000 million ‘letters’. If the 1% figure were correct, this would amount to 30 million letters difference, which would take 10 Bible-sized books to print. This is 50 times as much DNA as the simplest bacterium.3 This is actually a huge difference that far exceeds the ability of even the most optimistic evolutionary scenarios to create, even given the claimed millions of years.4”

Here are some other points to show the large difference:
- The Chimp genome is 13% larger.
- 6.4% of our genes are not shared (there are 689 extra genes in humans)
- 35 million base pair changes necessary (but we only have a few hundred thousand generations to do all of that and get those changes to spread through all of the human population)
- There are tens of thousands of rearrangements needed to the order of DNA from chimps to humans.
