TL;DR: Water measurements of total energy expenditure in humans, chimpanzees, bonobos, gorillas and orangutans are used to test the hypothesis that the human lineage has experienced an acceleration in metabolic rate, providing energy for larger brains and faster reproduction without sacrificing maintenance and longevity.
Journal ArticleDOI
Chimpanzee females queue but males compete for social status.

TL;DR: A new likelihood-based Elo rating method is developed and applied to characterize long-term rank trajectories in wild eastern chimpanzees and finds remarkable sex differences in rank dynamics, indicating that females queue for social status while males actively challenge each other to rise in rank.
Journal ArticleDOI
Maturation is prolonged and variable in female chimpanzees.
TL;DR: Improved estimates of maturation milestones in a population of wild female chimpanzees are provided and the importance of maternal factors in development is indicated.
Journal ArticleDOI

TL;DR: It is shown that males have higher paternity success when their mother is living in the group at the time of the offspring's conception in bonobos but not in chimpanzees.
