  • If a squirrel falls they’re probably not going to squish as hard as a monkey. Lots of scavengers also have forward facing eyes (ex racoons) and pandas notably have forward facing eyes and are herbivorous.

    I think the climbing and jumping theory is better than the predator theory on account that it explains why large aquatic animals aren’t selected for close frontal eyes.

    Plus many predators (cats notably) do climb and jump. Humans and monkeys also have werd postures that might lead to them falling over easier.

    In reality its probably never just one pressure that leads to these kind of evolutions.


  • Convergent evolution has more to do with environment and trophic structure than it has to do with lineage. Any animal that can produce a complex eye can have similar evolutionary pressure given similar environments unless there’s some other stronger pressure.

    Animals low to the ground or water often have slitted eyes (including goats who spend a of time with their heads down)

    From what I’ve seen Feyman was more than a little pedantic and he liked to emphasize that science doesn’t answer “why” it answers “how”. So if ICP asked that question Feyman would say “take an undergrad physics course because its not easy to explain in a soundbite”
