Q&A Four Question One

Q: Is a human more relevant in a lifeboat scenario with Coco the gorilla? Are we so close we are equal even in this situation?

I'm honestly unsure about this one. A gorilla certainly has the right to life and to be left alone. A higher valuation could be based on the animal's higher cognitive capacities. If these capacities are equivalent to mentally stunted humans, then is their moral value equal to that of a human? And further, is a mentally stunted human less morally valuable than a fully developed adult human?
