Caption: A muriqui monkey mother, infant and juvenile son are shown in their Brazilian forest habitat in 2011. According to new research by Karen B. Strier, a professor of anthropology at the University of Wisconsin–Madison, it is the monkey mothers who pull the strings in muriqui society to the reproductive advantage of their male offspring. The mere presence of mothers and other maternal kin helps male offspring connect with the right females at the right time.
