Researchers give us a peek into why our early ancestors had so many children.
Northwestern University researcher Lee T. Gettler suggests in a new anthropological model of human evolution that the fathers among our earliest human ancestors may have helped jumpstart human evolution by helping females out with their children.
Lee believes that the same paternal investment pattern resembles the kind of hands-on parenting many dads still display.
"Other men might have been highly involved with direct care, engaging in behaviors not unlike what involved fathers do today," Gettler, a doctoral candidate at Northwestern, told Discovery News.
The study was published in the February issue of the journal American Anthropologist.
According to the expert, dads in early human species would have aided in carrying children, as well as in their bathing, feeding, playing and teaching them the lessons of prehistoric life. (ANI)
