The phylogeny of general intelligence
« on: June 21, 2009, 11:51:00 AM »
A new study by Banerjee et al. (2009) shows that monkeys also vary in general intelligence: some monkeys are smarter than others. This findings supports the hypothesis that important aspects of human cognitive function most likely evolved from ancient neural substrates.

Might as well ask how ancient is evolution.
That which can be asserted without evidence can be dismissed without evidence.

As I've noted elsewhere, insects have brains and can be classically conditioned. This is a form of intelligence. I suspect thus there are then smart ants and no so smart ants. So these studies should be replicable even at that level.

firstly, evolution to human runs medusae - fishes - amphibia - reptilia - mammalia, insects are bay-line and have here nothing to the point
secondly, insects arose about 400 millions of years ago, and the nervous system possessed already primitive medusae from before 2 billions (in europe milliards) of years !
