I would have guessed the other way round.
Why? What force is it that compels molecules to organize into animal-like systems rather than plant-like systems?
If they can readily convert energy into new cells and reproduce then what difference plant or animal?
I'm still wondering why chemicals suddenly "acquire" a motivation to replicate themselves.
Why on earth do chemicals "care" if they reproduce?
A hydrogen molecule can survive forever wondering about the universe "mating" with this atom or that molecule. Why is it that somehow when it connects up with a certain group of other atoms they suddenly decide to repoduce (which takes an awful lot of energy).
No, microbes ate one another (like animals) before photosynthesis came along (i.e., plants).
I would have guessed the other way round.
Evolution is a religion.
A whale farts, and it becomes evidence for the missing link.
