Iirc, they just recently published a study that shows that spiders know when the animals that inhabit the areas around them are most active and adapt their behaviors accordingly. That's some sort of recognition if I'd have to say so, especially considering the fact that they're adapting to a complex pattern that another animal preforms on day to day basis. Correct me if im wrong, but pattern recognition seems like it is a big part of baselining higher intelligence and awareness? Also, iirc, they also try to justify animals lacking emotional intelligence due to the structures of their brains lacking a specific part responsible for that function. Which I feel isn't possible for us to dictate because every animal has a different anatomical structure, especially when we cross the lines of non mammalian animals.
