A U-M-led study of interbreeding between two species of modern-day howler monkeys in Mexico is shedding light on why it's so difficult to confirm instances of hybridization among primates – including early humans – by relying on fossil remains. The study analyzed genetic and morphological data collected from monkeys over the past decade. Liliana Cortés-Ortiz, an evolutionary biologist and primatologist and an assistant research scientist in EEB and the Museum of Zoology, authored the paper along with Mary Kelaita, a postdoctoral fellow at the University of Texas at San Antonio’s Department of Anthropology.
Watch for an EEB research feature coming soon. The story is being covered broadly in the media, including the Spanish language news outlets.
