Mountain gorillas, who live in close-knit social groups with siblings and non-siblings of both sexes throughout their lives, show distinct behavioral biases towards maternal versus paternal kin.

In mountain gorillas, as in certain human populations, relationships between group members can act as a social buffer, breaking the link between maternal loss, increased social adversity, and decreased fitness.

Newly recovered lumbar vertebrae belonging to Malapa Hominin 2, an adult female of the fossil hominin species Australopithecus sediba, demonstrate that this individual was adapted to upright posture and bipedal locomotion but also had adaptations for climbing in trees.

Among captive chimpanzees, higher agreeableness males and higher openness females survive longer.

The reconstitution of a functional envelope protein from an extinct hominid retrovirus reveals its receptor and an ancient host defense that may have led to the extinction of the virus.

Functional divergence of caspase 3 and 7 in vertebrate is mediated by key residue mutation.

Whole-genome in silico screening for stop codon contexts that produce elevated translational readthrough and peroxisome targeting reveals that in mammals, the amount of lactate dehydrogenase in the peroxisome is controlled by translational readthrough.
