Three questions unanswered by the theory of evolution are:
- How does evolution add information? Mutation explains how existing genetic information is changed, but it doesn't explain where new genetic information comes from.
- How can evolution be so quick? Millions of years can seem like a long time to the average person, but in terms of evolution, it's quite quick. Current evolutionary theory hasn't explained how a one-celled organism can evolve into an organism as complex as a human being in the time available in Earth's history.
- Where did the first living cell come from? In order for mutation and natural selection, processes essential to evolution, to operate, life must already exist. The current hypothesis is that life formed spontaneously from chemical reactions about 4 billion years ago, but is this really possible?
