Oh boy, I’m not a fan of TierZoo. The concept of ranking animals, especially in gaming terms, really rubs me the wrong way. Trying to conceptualize organisms, past and present, in such terms seems disingenuous, misleading, and perhaps supremacist (the conceit that some animals are inherently "better" than others).
Even relating animals so strongly with gaming can fall very quickly into the pit of desensitization and sensationalism. I’m just a person who enjoys casually learning about biology, so I'm also curious what professional biologists think about TierZoo and if they have similar criticisms of his work.
True, gaming can teach us a lot about the world around us, but taking it to such extremes like TierZoo does where the subject matter starts to get so oddly detached from reality is off putting. I think the problem with TierZoo is that there's a lack of nuance, depth, and frankly maturity. You can only take the gaming analogy so far before it starts becoming patently absurd and flawed. Edutainment can be fantastic, however when done like this I think it could do more harm than good in the long run.
