The emergence of longevous populations.
Repository Usage Stats
The human lifespan has traversed a long evolutionary and historical path, from short-lived primate ancestors to contemporary Japan, Sweden, and other longevity frontrunners. Analyzing this trajectory is crucial for understanding biological and sociocultural processes that determine the span of life. Here we reveal a fundamental regularity. Two straight lines describe the joint rise of life expectancy and lifespan equality: one for primates and the second one over the full range of human experience from average lifespans as low as 2 y during mortality crises to more than 87 y for Japanese women today. Across the primate order and across human populations, the lives of females tend to be longer and less variable than the lives of males, suggesting deep evolutionary roots to the male disadvantage. Our findings cast fresh light on primate evolution and human history, opening directions for research on inequality, sociality, and aging.

Robert F. Durden Distinguished Professor of Biology
Research in the Alberts Lab investigates the evolution of social behavior, particularly in mammals, with a specific focus on the social behavior, demography, life history, and behavioral endocrinology of wild primates. Our main study system is the baboon population in Amboseli, Kenya, one of the longest-running studies of wild primates in the world, ongoing since 1971.
James B. Duke Distinguished Professor Emerita of Evolutionary Anthropology
I have recently retired and am not taking on new students although I am continuing some research projects. I am interested in understanding the evolution of sociality, social structure, and the patterns of competition, cooperation and social bonds in animal species, including humans. Most of my work has focused on social mammals: lions and chimpanzees. For the last twenty five years I have worked almost exclusively on the long term Gombe chimpanzee project. I have gathered the data
