The finding, published in the journal Current Biology, reinforces the idea that girls choose dolls as a result of stereotypical socialization, as well as certain "biological predilections", reports Europa Press.

"Before, we thought we would carry these maderillos females more frequently than males and would stop when they had their own babies. We now know that both are correct, "says Wrangham.
