他们认为，如果这些沉默的基因以某种方式被重新激活，长期丢失的性状可能会重新出现。
If these silent genes are somehow switched back on, they argued, long-lost traits could reappear.
但是，如果沉默基因在600万到1000万年内退化，那么失去已久的性状如何在更长的时间内被重新激活呢？
But if silent genes degrade within 6 to 10 million years, how can long-lost traits be reactivated over longer timescales?
另一种更有趣的可能性是，使蜥蜴的脚趾成形的基因信息，以某种方式存活了几千万年甚至几亿年，而且被重新激活了。
Another more intriguing possibility is that the genetic information needed to make toes somehow survived for tens or perhaps hundreds of millions of years in the lizards and was reactivated.
