"Humans got smart because brains were selected. That process is continuing faster than ever." Hard to see this, Maurice. I know that you believe that affluence is correlated with wealth, but you must also know that number of offspring is negatively correlated with wealth. QED.

<<Humans got smart because brains were selected. That process is continuing faster than ever>> MQ Think Again --------------- Ants found to teach each other way to food Scientists call results unique By Reuters \| January 12, 2006 LONDON -- British researchers said yesterday that they had uncovered the first proof of teaching in animals: ants showing each other the way to food. The ants studied by scientists from Bristol University used a technique known as tandem running -- one ant led another ant from the nest to food. It was a genuine case of teaching as ant leaders observed by Nigel Franks and Tom Richardson slowed down if the follower got too far behind. If the gap got smaller, they speeded up. Tandem leaders also paid a penalty, because they would have reached the food four times faster if they had gone alone. But teaching had its advantages -- the follower ant learned much more quickly where the food source was. Information flows through the ant colony when followers are promoted to leaders, and the teaching starts over again. ''Teaching isn't merely mimicry. It involves the teacher modifying its behavior in the presence of a naive observer at some initial cost to itself," said Franks, who reported the findings in the journal Nature. ''We think real teaching involves a lot of feedback. This is to our knowledge the first example of formal teaching in non-human animals," he said. ''What's nice about this demonstration is that the ant is an animal with a small brain. The human brain is a million times larger and yet the ant is very good at teaching and learning." © Copyright 2005 The New York Times Company
