Many areas in animal behavior, including evolution of a) matings systems (e.g. monogamy, polygamy); b) sexual selection (differences between the sexes that make one sex better able to compete for the other sex - e.g., the peacock's tail); and c) differences in male-female sexual behavior, have been profoundly influenced by a paradigm known as "Bateman's Principle". In 1948, Bateman, working with fruitflies, concluded that males compete for females - some males gain many matings while others do not; most females do mate. Moreover, male fertility increased with the number of mates, but female fertility did not. These results were ascribed to the fact that males produce billions of sperm, while females have relatively few eggs. Consequently, males should indiscriminately try to mate with as many females as possible, but females should be discriminating, sexually passive, and mate only with one "best" male. Bateman predicted that females should favor monogamy, and males promiscuity. Because males compete for females, sexual selection should be more important in males. These ideas began to be questioned when modern data showed that, in some species, these predictions do not fit. Some males may carefully choose among females and even refuse to mate with "inferior" females. Presumably monogamous females may actively seek copulations with multiple males, and thereby increase their fertility.This symposium brings together experts to evaluate which aspects of Bateman's Principles are still valid, and how modern data on male-female sexual behavior and its effects on fertility may impact our understanding of Bateman's paradigm.

动物行为的许多领域，包括a）Matings系统的演变（例如一夫一妻制，一夫多妻制）； b）性选择（使一个性别更好地竞争另一种性别的性别之间的差异 - 例如孔雀的尾巴）； c）男女性行为的差异受到称为“贝特曼原则”的范式的深刻影响。 1948年，贝特曼（Bateman）与果蝇（Fruitflies）合作得出结论，男性竞争女性 - 有些男性获得了许多妆容，而另一些男性则没有。大多数女性都会伴侣。此外，男性生育能力随伴侣的数量增加，但女性生育力没有。这些结果归因于男性产生数十亿人的精子，而女性的卵相对较少。因此，男性应不加区别地尝试与尽可能多的女性交配，但是女性应歧视，性被动，并且仅与一个“最好的”男性相交。贝特曼（Bateman）预测，女性应该偏爱一夫一妻制和男性滥交。因为男性争夺女性，所以性选择在男性中应该更为重要。当现代数据表明在某些物种中，这些预测不合适时，这些想法开始受到质疑。有些雄性可能会小心地选择女性，甚至拒绝与“劣等”女性交配。据推测，一夫一妻制的女性可能会积极寻求多个雄性的交配，从而提高其生育能力。该研讨会汇集了专家，以评估贝特曼原理的哪些方面仍然有效，以及对男性性行为的现代数据如何及其对生育能力的现代数据如何影响我们对贝特曼对贝特曼的理解的影响。
