What exactly did snails adapt to overcome by merging the two sexes into one?Or were they always hermaphrodites?
Scientists believe that before the two-gender state that most animals, plants, and fungi now find themselves in, there was only one sex, and everybody could mate with everybody else.
If any organism is threatened by not finding a mate in time, could the trait of hermaphroditicism form
The switch between sexuality and parthenogenesis in such species may be triggered by .... a lack of males
