Flawed Analysis Casts Doubt on Years of Evolution Research

Below is a press release about the Methods in Ecology and Evolution paper ‘‘Residual diversity estimates’ do not correct for sampling bias in palaeodiversity data‘ taken from the University of Bristol.

Years of research on the evolution of ancient life, including the dinosaurs, have been questioned after a fatal flaw in the way fossil data are analysed was exposed by scientists from the universities of Reading and Bristol.

Studies based on the apparently flawed method have suggested Earth’s biodiversity remained relatively stable – close to maximum carrying capacity – and hinted many signs of species becoming rapidly extinct are merely reflections on the poor quality of the fossil record at that time.

However, new research by scientists at the University of Reading suggests the history of the planet’s biodiversity may have been more dynamic than recently suggested, with bursts of new species appearing, along with crashes and more stable periods.
