Considering that we have a whole class of lifeforms that have nothing like a head with eyes and mouth or limbs, the idea that this would evolve independently more likely than something completely different, is also possibly unfounded.
- harperlee 5y agoHaving two eyes, as a simple example, is arguably the cheapest way to perceive 3d at things-may-want-to-eat-me distance: just two points that enable triangulation. Similar constraints reduce the configuration space a lot. It still remains huge, but I don’t think someone that believes about certain convergence to be necessarily naive.
- ClumsyPilot 5y agoHaving three eyes, as a simple example, is arguably the cheapest way to percieve 360-degree view of things-may-want-to-eat-me. Plenty of animals that have 2 eyes and no 3d vision, they try to get as close to 360 coverage as possible.
