Protea plants help unlock secrets of species 'hotspots'

Researchers have created a family tree of 2,000 protea plant species, revealing that two regions – South Western Australia and the Cape Floristic Region – are experiencing accelerated speciation rates. This surge is linked to climate change approximately 10-20 million years ago, which led to hotter, drier conditions and vegetation fires.
