I'd hardly describe it that way. It took untold trillions of predator/prey interactions over the hundreds of millions of years that single celled life existed for it to happen. That's more or less brute forcing the problem and it took geologic timescales to happen.
If you ask me to point at a hurdle stopping civilizations from developing that looks awfully reasonable.
If by "paragraphs" you mean two sentences, sure.
If you'd bothered to read past those two sentences you'd see that I was making an offhand comment before answering the question.
