Research sheds light on developmental origin of early link between speech and cognition Human infants' responses to the vocalizations of non-human primates shed light on the developmental origin of a crucial link between human language and core cognitive capacities, a new study reports. Previous studies have shown that even in infants too young to speak, listening to human speech supports core cognitive processes, including the formation of object categories. Alissa Ferry, lead...

This is according to anthropological research on lemur infant care by Andrea Baden and colleagues...

Origins Of Menopause

In a study published in the Proceedings of the National Academy of Sciences, a team of scientists compared mortality and fertility data for seven species of wild primates to the data for a modern hunter-gatherer human population. The !Kung people of...

Monogamy Evolved As A Mating Strategy
2013-07-30 05:38:41

redOrbit Staff & Wire Reports - Your Universe Online The evolution of monogamy among male mammals appears to have been triggered by the threat of infants being killed by unrelated males, researchers reported on Monday in the journal PNAS. The study is the first to reveal this evolutionary pathway for the emergence of pair living, and contradicts the theory monogamy resulted from a need for extra parental care by the father. The researchers also found males were more likely to...

Orangutans Not The Swingers They Were Made Out To Be
2013-07-29 13:48:29

Lee Rannals for redOrbit.com - Your Universe Online Primatologists writing in the American Journal of Primatology found that great apes spend a large amount of time walking on the ground. Orangutans have been known as the king of swingers, but finding that the apes come down from the trees to forage or to travel could lead to implications for conservation efforts. Researchers traveled to the East Kalimantan region of Borneo to a place known as a hotspot for primates, including the...

Their hands are...
