>What would be weird and idiotic would be if a species of big cat that was particularly good at mimicking the sound of a human female in distress to lure human prey somehow springboarded from this strategy into a transformation into bipedal humanoids of equivalent sapience to humanity.
Evolutionary arms races are a real thing that result in extremely ridiculous adaptations due to one species constantly trying to outdo the other and vice versa. Mimics in particular can become borderline flawless if enough pressure is placed on them. (See pic related) A theoretical human predator wouldn't "springboard" straight from mimicking sounds to being a sapient humanoid, it'd start millions of years prior with a predator that mimics the calls of primates. Then as primates get smarter and form stronger social bonds, pressure is placed on the mimics to create more convincing acts if they want to stay fed. The predator may start walking upright a short time after human ancestors do, then start looking more human in response to apes shifting into human features. It's a snowball effect that only get more and more drastic as time goes on. Also, all of this is assuming a completely realistic world equivalent to our own, Frieren has fictional elements like magic that could also play a role in this transformation.
