aDNA revealed a model of domestication where an ancient guanaco population no longer exists, the loss of the ancient vicuña genetic variation in the modern populations, and frequently interbreeding practices.
A new hominin species has been unearthed in the Dinaledi Chamber of the Rising Star cave system in the largest assemblage of a single species of hominins yet discovered in Africa.
A transmissible cancer that arose in a marine mussel spread from a single animal to become a global pathogen affecting two other mussel species in both Europe and South America.
The discovery of new skeletal remains of Homo naledi in the Lesedi Chamber, South Africa, adds more evidence to our understanding of the morphology and behavior of this recently discovered species.
Scale-up of piped water coverage in the local community strongly protects against S. haematobium re-infection intensity among primary school-going children following treatment with praziquantel.
Independent dating techniques have established that the H. naledi fossils are between 236 and 335 thousand years old, indicating that small-brained hominins with relatively primitive body shapes co-existed with our early ancestors in Africa.
Long-term immune outcomes vary with age, for both adults and children in HIV-infected populations, e.g. long-term scaled carrying capacity is lower in HIV-infected younger individuals compared to older individuals.
In years with colder ocean temperatures, fur seal pups receive more maternal care and have a better energy balance, clearing hookworm infection earlier, which increases their chances of survival.
