The evolution of the Y chromosomes of different taxa (humans, plants and Drosophila) is considered as well as the degeneration processes that affected the autosomal ancestor (proto-Y chromosome). The acquisition of testis-expressed genes and their amplifications on the Y chromosome are discussed. In spite of the differences and the specificity of evolutionary forces driving their diversification, the molecular studies of the Y chromosomal structures reveal some unexpected similarities in different evolutionary lineages.
