Other claims from this paper (6)
- Observation Asexual organisms often occupy larger and more northern areas than sexual relatives.
- Mechanism Apomixis aided recolonization of the Alps after glacial retreat through establishment by single individuals.
- Observation Sexual hybrids or polyploids did not show geographical parthenogenesis relative to sexual diploid progenitors.
- Mechanism The authors suggest climatic oscillations triggered range shifts and crossing barrier breakdown.
- Mechanism Interspecific hybridization and polyploidy may have promoted recurrent origins of asexuality.
- Mechanism Interspecific hybridization and polyploidy may have reduced fitness of sexual progenitors.
