Abstract
The prevalence of autopolyploids in angiosperms has long been a subject of debate. Meurountzing (1936) and Darlington (1937) conclude d that autopolyploids were common and important evolutionary entities. However, Clausen et al. (1945) and Stebbins (1947) subsequently considered them rare, in part because the
criteria upon which interpretations of autopolyploidy were rendered were not rigorous. This position was reiterated by Grant (1981) decades later, although evidence was mounting that autopolyploid taxa might be important in natural populations (Lewis, 1980). As cytological and genetic data have accumulated, it has become increasingly apparent that the latter view is likely to be correct (Soltis et al., 2004b, 2007, 2010). However, it still appears that the majority of polyploids are allopolyploids (Parisod et al., 2010; Soltis et al., 2010), even though Ramsey & Schemske (1998, p. 467) conclude that 'the rate of autopolyploid formation may often be higher than the rate of allopol yploid formation.' In this letter we survey the literature to assess whether allopolyploids are indeed the prevailing cytotype in nature. Using our new estimates for the incidence of autopolyploidy and allopolyploidy, we discuss some of the evolutionary dynamics that may be driving their frequencies in nature. Finally, we suggest avenues for future research on polyploidy that build on our results and other recent progress in the field.
