Evolutionary adaptation without sex. On pages 335–345, Michael Seidl and Bart Thomma argue that sexual reproduction is not a prerequisite for evolutionary success. They postulate that presumed asexual organisms, such as certain fungi, have developed different means to compensate for the lack of sex. The mechanisms employed by these organisms include single nucleotide polymorphisms caused by replication errors, horizontal DNA transfer and transposable elements. Furthermore, genomic rearrangements resulting in translocation, duplication and deletion of genetic material can help these organisms adapt to changing environments.
