The knee-jerk response to this account is to think " aha - maybe some of those novel har sequences are running some new human-specific brain module or widget ! Like my consciousness ! "
A researcher picks out a har ( e.g. har34 ) , figures out what gene it 's contiguous to , and then asks : where and when is that gene switched on / off during embryological development ?
一位研究员挑出一个har，指出它与什么基因相连，然后问：在胚胎发育期基因是何时何地被打开或关闭？
Just as in our hypothetical example , where a group of neurons failed to secrete a hormone and the second phalanx of neurons wandered off to find new targets , a mutant har is more likely to result in some human-specific pattern of regional brain differentiation .
