the evolution of the Psittaciformes (parrots, parakeets) as derived from
the sequences of selected sex-chromosomal DNA sequence elements.
Our studies of the evolution of the spindlin
gene in birds has enabled us to generate a better understanding of the
evolutionary relationships between the different members of the Psittaciformes
(Parrots and parakeets). Such understanding is important in order to
obtain a better understanding of avian evolution in general, but may
also give important information about the interaction between avian
hosts (i.c. Psittaciformes) and their parasites (i.c. viruses). The
Psittaciformes are a unique avian family of which the nearest relatives
among the other birds are unknown. Molecular procedures have been widely
employed to find the interspecific relationships between animals, plants,
