人类与其他灵长类动物的不同之处在于其显著延长的生长期。出生后大脑发育的胎儿模式的持续性是人类发育的另一个重要特征（1）。在这里，我们提出了一个180万年前的Mojokerto儿童（Perning 1，爪哇），唯一保存完好的直立人婴儿头骨，通过计算机断层扫描分析的结果。与大量现存人类和黑猩猩的比较表明，该个体死亡时约为1岁（0-1.5岁），其颅内容量为平均成年黑猩猩的72-84%。直立人这种相对大脑生长模式与现存猿类相似，但与现存人类不同。这意味着，在认知能力的发展存在重大差异之间的H。直立人和解剖学上的现代人。
Humans differ from other primates in their significantly lengthened growth period. The persistence of a fetal pattern of brain growth after birth is another important feature of human development(1). Here we present the results of an analysis of the 1.8-million-year-old Mojokerto child (Perning 1, Java), the only well preserved skull of a Homo erectus infant, by computed tomography. Comparison with a large series of extant humans and chimpanzees indicates that this individual was about 1 yr (0-1.5 yr) old at death and had an endocranial capacity at 72-84% of an average adult H. erectus. This pattern of relative brain growth resembles that of living apes, but differs from that seen in extant humans. It implies that major differences in the development of cognitive capabilities existed between H. erectus and anatomically modern humans.
