Because when researchers looked at captive prairie dog populations, it suggests that these communications aren't actually genetically inherent. The ability to communicate like this is genetically inherent, but the knowledge of this communication is of a learned nature. They don't just simply know it. Captive bred individuals in zoos, for example, they fail to produce the complex and what they call the structurally nuanced alarm calls that you would observe in the wild. And when they were faced with stimuli, their vocalizations default to simple, repetitive patterns to lack any descriptive variation. So what that indicated to researchers is that the syntax of descriptive communication has to be learned intergenerationally intergenerationally... Oh my God. Intergenerationally from mature colony members. Let me drop it.
