A new study published today in Proceedings of the Royal Society B investigates the genetic and geographical relationships between different forms of crimson rosellas and the possible ways that these forms may have arisen. Dr Gaynor Dolman of CSIRO's Australian National Wildlife Collection says there are three main color 'forms' of the crimson rosella – crimson, yellow and orange – which originated from the same ancestral population and are now distributed throughout south eastern Australia. "Many evolutionary biologists have argued that the different forms of crimson rosellas arose, or speciated, through 'ring speciation'," she says. Read More...
