Teno's Questions: Digestion


Which came first, the digestive system, the food to be digested, the knowledge of the need for food, the ability to find food, to know what food is, what to consume and how to consume it, the digestive juices, or the body's ability to resist being destroyed by the same acids that digest food?

This one is simple ignorance of biology. "Simple" organisms can absorb molecules that provide energy directy. This sounds like Teno is imagining a modern mamal without a digestive system needing to evolve one. This would be a strawman.
