There is a great statistic called the encephalization quotient that is simply log brain mass divided by log body mass. There is a fairly strong correlation (https://universe-review.ca/I10-83-brainmass.jpg https://universe-review.ca/I10-83-brainmass.jpg), but you find that species which deviate from the best fit line (biggest residuals) tend to be the species we associate as intelligent or not intelligent. Humans have the largest magnitude residual.
- pennaMan 10y agoWhat species is the point right next to humans? It's not a primate, interestingly.
- LeifCarrotson 10y agoIt's probably a dolphin or porpoise. Not only do they have some of the highest EQ of non-primates, they're also the right weight range: https://en.wikipedia.org/wiki/List_of_cetacean_species#Family_Delphinidae:_oceanic_dolphins https://en.wikipedia.org/wiki/List_of_cetacean_species#Famil... You may think of bottlenose dolphins as representative of the whole family, but they actually are much larger than most of their brethren.
- neonnoodle 10y agoSome kind of cetacean.
