Neandertal relative bred with humans
Known only through DNA extracted from a scrap of bone, a Siberian hominid group suggests a much more complicated prehistory for Homo sapiens.
- Life
Genes separate Africa’s elephant herds
Genetic work reveals forest and savanna pachyderms as distinct species.

Gene genesis
About a quarter of present-day life's DNA blueprint had been sketched out by 2.8 billion years ago, a new analysis finds.
- Animals
Female chimps play with ‘dolls’
Youngsters mimic mothering by cradling sticks, reigniting debate over sex differences in toy choices.

Bugged forests bad for climate
Trees savaged by pine beetles are slow to recover their ecological function as greenhouse gas sponges.

Climate action could save polar bears
Cutting fossil fuel emissions soon would retain enough sea ice habitat for threatened species, scientists say.
