Bees point to new evolutionary answers

(Flinders University) Evolutionary biology aims to explain how new species arise and evolve to occupy myriad niches -- but it is not a singular or simplistic story. Rare bees found in high mountain areas of Fiji provide evidence that they have evolved into many species, despite the fact they can't readily adapt to different habitats. These bees -- discovered by a team of Australian researchers -- serve as a major warning about the impact of ongoing human-induced climate change and loss of biodiv...
