The study examines the impact of body build on differential fertility patterns in 93 !Kung San and 85 Kavango females from northern Namibia. In both groups shorter females had more offspring, but also more dead offspring, than taller females. The interaction between body weight and fertility was different in both groups and may be due to different nursing behaviour. There was a positive relationship between the typical pedomorphy and fertility in the !Kung San, and directional selection processes may be important.
该研究考察了体型对纳米比亚北部93名!昆桑女性和85名卡万戈女性生育模式差异的影响。在这两组中，较矮的女性比高个子女性生育的后代更多，但夭折的后代也更多。两组中体重与生育能力之间的相互作用有所不同，这可能是由于不同的哺乳行为所致。在!昆桑人中，典型的幼态持续与生育能力之间存在正相关关系，定向选择过程可能很重要。
