The likelihood that dioecy could evolve via androdioecy is examined. It is concluded that
female-sterility mutations are unlikely to be able to invade populations of self-compatible …

large and presumably costly opposite-sex structures that are sterile. This is termed 'cryptic …

Darwin's theory of natural selection successfully explains why organisms are designed to
meet environmental challenges, his simple proposal being that heritable traits that confer …
