Molecular evolution programs are heavy on bodies but skimpy on heritable information. 分子進化程序對物體而言很有分量，對遺傳信息而言分量不足。
The important thing, scientifically, is having a tool to trace molecular evolution, which Schweitzer said is the key to the tree of life. 就科學而言，重要的是擁有了一種追蹤分子演化的工具，史懷哲說，這是生命之樹的關鍵。
Comparisons of pseudogenes in related genomes can nonetheless reveal important information about the history of specific genes and the general workings of molecular evolution. 然而比較相近生物基因組的偽基因，卻可揭露特定基因和一般分子演化的重要資訊。
