What humans and primates both know when it comes to numbers

(University of Rochester) University of Rochester researchers have found that adults and children in the US, adults from a 'low numeracy' tribe in Bolivia and rhesus monkeys ALL possessed the ability to distinguish between large and small quantities of objects, regardless of the surface area they occupy. This ability is likely a shared evolutionary trait, according to a study published in Nature Communications. The nonverbal visual tests could be used in assessing early math education in young children.
