More than 250 million years ago, something huge happened to the Earth: the Permo-Triassic Mass Extinction (PTME), which wiped out almost all of the planet's species. Now a group of scientists has uncovered important details about how the event's survivors adapted in a harsh, drought-stricken stretch of South Africa. The Conversation Africa's science and technology editor Natasha Joseph asked lead researcher Dr Jennifer Botha-Brink to explain what she and her colleagues have learnt -- and what this might teach us about species' adaptation to climate change.
