They can, however, tell their friends from their enemies.
Scientists have shown that this ability is present from the first few months oflife, suggesting it is something that we are all born with.
Researchers studied how two groups of babiesreactedtoagame in which

The helpful toy was preferred by all 12 of the six-month-olds and 14 of the 16ten-month-olds, the scientific journal Nature reported.
The researchers from Yale University said: This supports the view that ourability to evaluate people is a biological adaptation, universal and unlearned.
Researcher Kiley Hamlin said it was likely the phenomenon had its roots deep inevolution, with the ability to tell the …
