Multiple Diverse Circoviruses Infect Farm Animals and Are Commonly Found in Human and Chimpanzee Feces
TLDR
It is shown that the genetic diversity of small circular DNA viral genomes in various mammals, including humans, is significantly larger than previously recognized, and frequent exposure through meat consumption and contact with animal or human feces provides ample opportunities for cyclovirus transmission.

Dominance, aggression and testosterone in wild chimpanzees: a test of the ‘challenge hypothesis’
The ‘challenge hypothesis’ posits that variation in male testosterone levels is more closely associated with aggression in reproductive contexts than it is with changes in reproductive physiology.Expand
Generation times in wild chimpanzees and gorillas suggest earlier divergence times in great ape and human evolution
TLDR
The human–chimpanzee split is dated to at least 7–8 million years and the population split between Neanderthals and modern humans to 400,000–800,000 y ago, which suggests that molecular divergence dates may not be in conflict with the attribution of 6- to 7-million-y-old fossils to the human lineage and 400,,000-Y-old bones to the Neanderthal lineage.

Origin of the human malaria parasite Plasmodium falciparum in gorillas
TLDR
Findings indicate that P. falciparum is of gorilla origin and not of chimpanzee, bonobo or ancient human origin. Expand
Dominance, cortisol and stress in wild chimpanzees (Pan troglodytes schweinfurthii)
TLDR
It is suggested that dominant chimpanzees experience significant metabolic costs that must be set against the presumed reproductive benefits of high rank, and metabolic stress may mediate the relationship between rank and cortisol in other social mammals. Expand
Recent developments in the study of wild chimpanzee behavior
TLDR
Results from field research conducted in the Kibale National Park, Uganda are focused on, giving special emphasis to five areas: social organization, genetics and behavior, hunting and meat-eating, inter-group relationships, and behavioral endocrinology. Expand
Origin of the human malaria parasite Plasmodium falciparum in gorillas.
TLDR
Findings indicate that P. falciparum is of gorilla origin and not of chimpanzee, bonobo or ancient human origin. Expand
The energetics of lactation and the return to fecundity in wild chimpanzees
TLDR
The metabolic load of lactation in chimpanzees is examined, suggesting that the slow reproductive pattern in wild chimpanzees results not only from the direct expense of milk production but also from the long period that mothers require to recover their physical condition in a food-limited environment. Expand
Comparative rates of violence in chimpanzees and humans
TLDR
Preliminary data support Boehm’s hypothesis that chimpanzees (Pan troglodytes) and humans have similar rates of death from intraspecific aggression, whereas chimpanzees have higher rates of non-lethal physical attack. Expand
