This an arbitary threshold that makes it trivially impossible for any species that can't master human languages (which is any known species except humans) to have rights. Consider what a bee on BN (Bhacker News) might say in an alternative reality >> We do give humans protections, and those protections are roughly proportionate to (our believes regarding) their cognitive abilities. If some human started waggle dancing about human rights, those would exist pretty much immediately. It is not fair for bees to judge you on how much you can waggle dance (their communication style) before giving you rights, the physiological requirement is irrelevant to your moral worth and impossible to achieve. Intelligence is similarly irrelevant to moral worth. It's just the ability to solve problems, spicier definitions include things like recursive modelling (an entity capable of self-reflection) and self-preservation. None of this has the slightest thing to do with morality or ethics, a trivial counter example that satisfy all would be nation-states, they solve problems, they are capable of self-modelling, they seeks self-preservation (to astonishing lengths).
