The data above, and the literature reviewed, demonstrate that in 4 significant morphological characteristics the neuro-skeletal topology of the human basicranial regions is unique, and does not resemble that of any extant non-human primate at any fetal or postnatal age. These characteristics are: 1. the shape of the cranial base; 2. the composition of the anterior and posterior portions of that base; 3. the extent, or degree, of basicranial flexion; and 4. the extent, or degree, of brain flexion. On these bases, the craniological implications of Bolk's fetalization hypothesis cannot be supported.
上述数据以及所综述的文献表明，在四个重要的形态学特征方面，人类颅底区域的神经骨骼拓扑结构是独特的，在任何胎儿期或出生后阶段都与现存的非人类灵长类动物不同。这些特征是：1. 颅底的形状；2. 该颅底前后部分的组成；3. 颅底弯曲的程度；4. 脑弯曲的程度。基于这些依据，博尔克胎儿化假说的颅骨学意义无法得到支持。
