2015 | Jessica Lynch Alfaro, et.al – Biogeography of squirrel monkeys (genus Saimiri): South-central Amazon origin and rapid pan-Amazonian diversification of a lowland primate

ISG faculty, Dr. Jessica Lynch Alfaro, Dr. Michael E. Alfaro, et al, have published a paper titled “Biogeography of squirrel monkeys (genus Saimiri): South-central Amazon origin and rapid pan-Amazonian diversification of a lowland primate” in Molecular Phylogenetics and Evolution. Abstract: The squirrel monkey, Saimiri, is a pan-Amazonian Pleistocene radiation. We use statistical phylogeographic methods to create a mitochondrial DNA-based timetree for 118…

Endangered Monkeys in the Amazon Are More Diverse Than Previously Thought, UCLA Study Finds

Research by UCLA life scientists and 50 colleagues sheds new light on the biological differences among more than 150 species of monkeys in South America, many of which are endangered. Their findings could be particularly important in shaping efforts to conserve the biodiversity of primates in South America. The scientists have resolved a dispute over whether a small population of…

Mapping Human Disease: ‘Not All Pathogens Are Everywhere’

Researchers at North Carolina State University have for the first time mapped human disease-causing pathogens, dividing the world into a number of regions where similar diseases occur. The findings show that the world can be separated into seven regions for vectored human diseases – diseases that are spread by pests, like mosquito-borne malaria – and five regions for non-vectored diseases,…

How Evolutionary Principles Could Help Save Our World

The age of the Anthropocene–the scientific name given to our current geologic age–is dominated by human impacts on our environment. A warming climate. Increased resistance of pathogens and pests. A swelling population. Coping with these modern global challenges requires application of what one might call a more-ancient principle: evolution. That’s the recommendation of a diverse group of researchers, in a…

Human Altruism Traces Back To the Origins of Humanity

Humans are generally highly cooperative and often impressively altruistic, quicker than any other animal species to help out strangers in need. A new study suggests that our lineage got that way by adopting so-called cooperative breeding: the caring for infants not just by the mother, but also by other members of the family and sometimes even unrelated adults. In addition…
