Abstract Amoeboid protists have always raised intriguing questions about sex in eukaryotes. Classical studies failed to detect meiotic process or sex in several groups. The advent of modern techniques allows for the study of eukaryotic sex at the level of genes known to be involved in the process. Recent phylogenetic studies have demonstrated probable evolutionary relationships among diverse amoebozoan groups, but the presumed asexual lineages do not form a clade in any modern phylogenies. Sex might have been lost several times among members of Amoebozoa, but which evolutionary pressures would drive sexual lineages to an asexual way of life? Would sex have been lost at all? (AU) | |
