A study published in the journal Nature has found that ancient human populations consumed milk during adulthood long before we were able to digest lactose beyond infancy. The genetic variant that allows us to do so was not increased in frequency by milk consumption, but by famine and infection, according to their hypothesis.

Climate change is causing a mass extinction of species, but for birds, this loss of biodiversity has wider implications. In research published in the journal Current Biology, researchers use statistical models to predict that this extinction will decrease morphological diversity among the remaining birds at a faster rate than species loss alone.
