“For instance, owl monkey males live longer than females and the males play a big role in infant care in that species,” he said, noting such males have two different sex chromosomes.

The study confirms what one of its authors, Eduardo Fernandez-Duque, an evolutionary anthropologist at the University of Pennsylvania who leads the Owl Monkey Project, had long suspected.

For 18 years, he and other Penn researchers have been observing the Azara’s owl monkey in the Chaco region of Argentina.

In the new study, published in the Proceedings of the Royal Society B, the researchers performed genetic analysis on 35 offspring born to 17 owl monkey pairs and confirmed that the parents were monogamous for the mating season.

In 2000, they reported that an owl monkey connected to the Internet had controlled an arm located 600 miles away.
