Martin Daly and Margo Wilson stated in their 1999 book, 'The Truth about Cinderella: A Darwinian View of Parental Love': 'Evolutionary thinking led to the discovery of the most important risk factor for child homicide – the presence of a stepparent. Parental efforts and investments are valuable resources, and selection favors those parental psyches that allocate effort effectively to promote fitness. The adaptive problems that challenge parental decision-making include accurately identifying one's offspring, allocating resources among them with sensitivity to their needs and abilities, and converting parental investment into fitness increments.... Stepchildren were seldom or never so valuable to one's expected fitness as one's own offspring would be, and those parental psyches that were easily parasitized by just any appealing youngster must always have incurred a selective disadvantage.'
