Abstract

Close
- Sex chromosomes are ubiquitous in birds but our understanding of how they originated and evolved has remained incomplete. Recent work by Tsuda et al. on tinamou and ratite birds suggests that, although all bird sex chromosomes evolved from the same pair of autosomes, the Z and W sex chromosomes have diverged from one another several times independently. This parallel evolution of the avian W presents a means for comparison in studies of sex chromosome evolution, which could help us understand more about the general forces that shape the development of all types of sex chromosome.
