More wild theorizing:-"If these polyamidines hitched a ride to the Earth in earlier epochs when the Earth was being bombarded by outer Solar System material, they would come into contact with water. However, these particular polymers will resist being broken down for some time. Instead, they replace their side chains with the carbohydrates characteristic of proteins. -In this way, they create partial proteins, and this might be a way that autogenesis based on proteins began on the early Earth. The inner planets also have the advantage of containing phosphorous, sulfur and iron which are unavailable in the outer planets, and these metals speed up catalysis. -Deacon is adamant that whole solar systems are needed to generate life, not just terrestrial planets with water. Life probably needs a solar system similar to our own to start, although autogenic processes could still occur in a system that only has gas giants." -
