Washington, April 29 (IANS) Monkeys share a number of similarities with humans, including the capacity for memory. They can recall rudimentary shapes and reproduce them on a touch screen, a study shows.

Benjamin Basile, psychologist at the Emory University, US, said: “For the first time, monkeys can actually show us what they recollect, and their test results are directly comparable to human tests.”

“They might be able to recollect other types of information that would be useful to them in the wild,” added Basile, according to the journal Current Biology report.

Basile and his associate Robert Hampton trained a group of rhesus monkeys on a recall test to reproduce a simple figure on a touch screen from memory, according to an Emory statement.

Researchers said that the ability of rhesus monkeys to recall what they have seen suggests that it is not dependent on language and might have been present in a common ancestor 30 million years ago.
