摘要

迄今为止，人们主要认为少女怀孕是一个围产期和社会问题，而忽视了其生物学和进化方面的问题。在本分析中，我们讨论了一个假设，即少女怀孕可能代表了一种适应性最大化策略，换句话说，是对女性相对较短的生殖期的有效利用。然而，生长学、灵长类学、历史人口学和生活史研究的结果却与这一假设相矛盾。青少年早孕(16岁以下)似乎是最近出现的一种现象，这是由于性成熟程度在长期加速趋势中下降所引起的。

[Teenage pregnancies from the viewpoint of evolutionary biology].

Teenage pregnancies have been considered mainly as perinatological and social problem up to now, in contrast biological and evolutionary aspects were neglected. In the present analysis the hypothesis is discussed that teenage pregnancies may represent a fitness maximizing strategy, with other words an efficient use of the relatively short female reproductive span. Results from auxology, primatology, historical demography and life history research, however, are in contradiction to the hypothesis. Extremely early teenage pregnancies (below the 16th birthday) seem to be a recent phenomenon caused by the decline of sexual maturation in course of the well described secular acceleration trend.
