A human brain has 10,000,000,000 cells so a colony of 40,000 ants has collectively the same size brain as a human. If the human population is 6,760,000,000 (2009) and the ant population is 1 quadrillion 1,000,000,000,000,000 (1999). If my mathematics is correct the brain cell count of the ant population is nearly 4 times that of the human population. How’s that for some useless information?
