The article discusses why some organisms reproduce sexually even though it seems like a lot of work. The researchers found that switching between sexual and asexual reproduction can be the best strategy, but most organisms stick to just one. They think this might be because sexual conflict can make it hard for new strategies to take over. When organisms can choose when to reproduce sexually, it can cause problems between males and females, leading to strong pressure for both to get their way. The researchers suggest that new strategies are more likely to succeed when they can avoid mating, have negative effects on mating success, and can have lots of babies without mating.
