Experiments on some fairly primitive animals have shown that they can count 1,2,3 and manipulate other quantities by ratio .
See New Scientist 20 Jun 2009 p37 "Animals that count" .
I treated this in some detail in "Primitives_0" ( 8/06/2006) and "Primitives_1" ( 5/03/2007) . See http://andreswhy.blogspot.com
Experimentation on Monkeys , salamanders , fish , bees , horses has confirmed that the primitive counting center is very old . It can count to 3 , then a different comparison mechanism is used .See the articles .
Humans , of course , cannot be counted upon , especially males .
The only known macroscopic quantum objects .
