Nope. Evolution doesn’t have levels. That’s an outdated 19th century idea. A sponge is a vastly more hardy organism than humans in the face of global catastrophe. When earth nearly froze over in the Cryogenian, sponges were there and they survived fine. We are smarter, but we are more fragile. Our intelligence, endothermy, high nutrient requirements. All the things that have allowed us to make a civilization, brings with it a volatility.
Evolutionary planes is kind of an 1800s idea where guys were trying to place humans at the top. Evolution is just about whatever body plans are good enough to reproduce in the moment. There’s plenty of plants and animals which have evolved to be more simple (like many parasites). Plenty of species can also evolve themselves into a corner, where it’s what works good in the moment but they will die out when conditions change
