Climatic stability resulted in the evolution of more bird species

More species of birds have accumulated in genera inhabiting climatically stable areas. This is shown by a new study from Umea University.Bar-tailed Godwit [Credit: Umea University]"The explanation may be that a stable climate makes it more likely that diverging lineages persist without going extinct or merging until speciation is completed, and stability reduces the risk for extinction in response to climatic upheavals," says Roland...
