Tool behaviour of long-tailed macaques leaves archaeological signatures that differ between populations despite similar ecological conditions, highlighting the potential for diversity in material culture.
Environmental transmission is atypical of symbionts that have undergone genome degradation, yet genetically reduced deep-sea anglerfish symbionts likely persist in the deep sea biome in search of a new host.

Despite risks of infection and reduced fitness, tooth fracture frequency in gray wolves increases rapidly when prey are scarce because they must consume carcasses more completely.
After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.
