句子结构
 

主语：only basic instincts

 

谓语部分：are carried in the genes of newborn baby,

 

伴随状语：other skills being learned from others in the community as the baby grows up

   其中——
　　【逻辑主语】other skills
　　【被动语态的现在分词短语】being learned from others in the community as the baby grows up（other skills being learned 指逐步被学习）
 
分词短语可以作时间、原因、条件、方式和伴随状语.如果分词的行为者不是句子的主语,这个分词就需要带有自己行为者作逻辑主语.这种逻辑主语是独立于句子主语的另一个主格形式,因此这种结构就称作独立主格结构.
 
other skills being learned … 正是这种结构,即“其他技能是被学习而来”.
 
作伴随状语的独立主格结构也可以改写如下：
 

用 and 连接：Only basic instincts are carried in the genes of newborn baby and other skills are learned from others in the community as the baby grows up.

用while 表示转折：Only basic instincts are carried in the genes of newborn baby,while other skills are learned from others in the community as the baby grows up

 
参考译文：唯一的本能是由新生儿的基因携带的,其他技能则是随着这个婴儿的成长通过身边的其他人习得而来的.
