Abstract：
The evolutionary history of modern birth mechanism is now a renewed interest in obstetrical papers. The purpose of this work is to review the literature in paleo-obstetrical field. Our analysis focuses on paleo-obstetrical hypothesis, from 1960 to the present day, based on the reconstruction of fossil pelvis. Indeed, these pelvic reconstructions usually provide an opportunity to make an obstetrical assumption in our ancestors. In this analysis, we show that modern birth mechanism takes place during the emergence of our genus 2 million years ago. References are made to human specificities related to obstetrical mechanism: exclusive bipedalism, increase of brain size at birth, metabolic cost of the pregnancy and deep trophoblastic implantation.
摘要：
现代出生机制的进化史现在对产科论文重新产生了兴趣。这项工作的目的是回顾古产科领域的文献。我们的分析重点是古产科假设，从1960年到现在,基于骨盆化石的重建。的确,这些骨盆重建通常为我们的祖先提供了一个产科假设的机会。在这个分析中,我们表明，现代出生机制发生在两百万年前我们属的出现期间。参考了与产科机制相关的人类特异性：排他性两足动物，出生时大脑大小的增加，妊娠和深层滋养细胞植入的代谢成本。
