Humans, great apes, and elephants, species all well known for their high intelligence, are the only others known to have spindle cells. [21]: 242 Spindle neurons appear to play a central role in the development of intelligent behavior. Such a discovery may suggest a convergent evolution of these species. [22]
For example, dogs (a social species) have a higher EQ than cats (a mostly solitary species). Animals with very large flock size and/or complex social systems consistently score high EQ, with dolphins and orcas having the highest EQ of all cetaceans , [ 34 ] and humans with their extremely large societies and complex social life topping the list ...
[127] [128] These values are similar to the accepted variance in IQ explained by a similar single factor known as the general factor of intelligence in humans (40-50%). [129] However, results from a recent meta-analysis suggest that the average correlation between performance scores on various cognitive tasks is only 0.18. [ 130 ]

Scientists have recently discovered a new primate species in Myanmar’s central forest. However, the Popa langur, named after nearby Mount Popa, is tragically already on the verge of extinction.
